...reported in 1994. The Intel P5 chip was found to have a floating point unit bug that made digital divide operation in algorithms flaw after the 4th decimal point. I will also be touching on the contributions of Professor Thomas R. Nicely and the time line on which he brought attention to the bug from the Intel P5. The Pentium FDIV bug The Pentium FDIV bug was first discovered by a professor named Thomas R. Nicely from Lynchburg College in Virginia. He discovered there were a few missing entries in the lookup table by the digital divide operation algorithm. Sadly Intel knew about the bug when they were testing the chip in June of 1994. Intel’s managers decided the error would not affect as many people as it would to issue a recall, and that they should not inform anyone outside the company. Later thet same month Dr. Nicely, a professor of mathematics noticed small differenced in two sets of numbers. Dr. Nicely spent months eliminating possible causes such ad PCI bus errors and compiler artifacts. October 19th after testing on several 486 and Pentium-based computers Dr. Nicely was certain that the error was caused by the Intel P5 processor. On the 24th of October he contacted Intel technical support and the support representative confirmed the error and said that it was not reported before. Then on October 30th after receiving no more information from Intel he sent an email message to a few people, announcing his discovery of a bug in the Intel P5 processor. From there...

...Ariel Torrente NT1110 Unit 5 Analysis 7/27/2013 Pentium Flaw The Pentium flaw also nicknamed the Pentium FDIV bug, was an identified error in the Intel P5 Pentium floating unit. The presence of the bug can be checked manually by performing the following application that uses native floating numbers, including Windows Calculator or Microsoft Excel in Windows 95/98 (Pentium FDIV bug). The Pentium flaw was discovered byProfessor Thomas R.Nicely at Lynchburg Collwge,Virginia USA (Emery, Vince). Dr.Thomas R Nicely is a mathematic professor, noticed a small difference in two sets of numbers, he always double-checks his work by computing everything twice, two different ways (Emery, Vince). Dr.Nicely spent months successively eliminating possible causes such as PCI bus errors and compiler artifacts (Emery, Vince). Intel wanted to keep to keep the Pentium flaw a secret, after Intel testers discovered a division error in the Pentium chip (Emery, Vince). Intel managers decided that the error wouldn’t affect many people, therefore no one outside of the company was not informed (Emery, Vince). The pandemonium over Intel’s Pentium chip cost the company millions of dollars and could have been prevented and became an uproar on the internet (Emery, Vince). This was Intel’s first mistake and the company was given a reputation that made Intel not a trustworthy company and not disclosing that information made them seem to be hiding a sinister secret (Emery, Vince). After several tests on...

...1994, Intel discovered the floating-point unit flaw in the Pentium microprocessor. Professor Thomas Nicely, a professor of mathematics at the Lynchburg College, had written code to enumerate primes, twin primes, prime triplets, and prime quadruplets. Professor Thomas Nicely noticed some inconsistencies in the calculations on June 13th , 1994 shortly after adding a Pentium system to his group of computers, but was unable to eliminate other possible factors (such as programming errors, motherboard chipsets, etc.) until October 19, 1994. On October 24th, 1994 he reported the flaw he encountered to Intel. According to Professor Thomas Nicely, the person that he contacted at Intel later admitted to Intel being aware of the flaw since May 1994. The flaw was discovered by Intel during testing of the FPU for its new P6 core, which was first used in the Pentium Pro. Professor Thomas Nicely sent an email describing the flaw that he had discovered in the Pentium floating point unit (FPU) to various contacts, requesting reports of testing for the flaw on the 486-DX4s, Pentium and the Pentium clones. The flaw in the Pentium FPU (floating-point unit) was quickly verified by other people around the Internet, and became known as the Pentium FDIV bug (FDIV is the x86 assembly language instruction for floating point division). An example of the flaw was found where the division result returned by the Pentium microprocessor was off by about 61 parts per million. On November 7, 1994 the story first...

The flaw was discovered by Intel during testing of the FPU for its new P6 core, which was first used in the Pentium Pro. An example of the flaw was found where the division result returned by the Pentium microprocessor was off by about 61 parts per million. In November, 1994 the story first broke in an article published in Electronic Engineering Times. In the story, Intel says it has corrected the glitch in subsequent runs of the chip, and Intel dismisses the importance of the flaw saying, "This doesn't even qualify as errata." The story was later picked up by other national and international media. On November 30, 1994 Intel released an in-house study of the flaw, "Statistical Analysis of Floating Point Flaw in the Pentium Processor" H.P. Sharangpani and M.L. Barton, Intel Corporation. The study on the processor minimized the potential impact of the flaw on the majority of the users. December 12, 1994 IBM decides to do their own study on the Pentium microprocessor chip challenging Intel's analysis. They concluded that the FPU flaw will seriously impact the work of a vast majority of users both within and outside the scientific community. The earlier denial about the chip was poor handling by Intel and cost them their customer’s faith...

...Term Paper: History of Intel and its microprocessors The microprocessor is a chip made of silicon that holds a central processing unit. Both the term’s central processing unit or CPU and microprocessor can be used and mean the same thing. The human brain has been compared to a microprocessor. Microprocessors are ultra fast calculators and what makes a microprocessor appear intelligent is the speed at which it can process data. The electronics industry names, microprocessors first by makers name and then model family name or number. A recent example, are the Intel Core i7 and AMD FX 8 Core Black Edition. Microprocessors provides scientist, engineers, architects, graphic designers, researchers, and other professionals with the processing power users to perform all the many functions needed to do their jobs and make new discoveries and explore what before could not have been even imagined. The history of microprocessors will be covered; this includes the history of Intel Corporation, important highlights in the development of the microprocessor. All digital computers use electronic switches. These switches represent binary digits or bits. The first computers used vacuum tubes as switches to represent on-or-off binary data, but vacuum tubes had many problems. Without the invention of the transistor, microprocessors and the modern computer would not be possible. Bell Laboratory engineers John Bardeen and Walter Brattain invented the transistor in 1947 (transistor). Transistors...

...In June, 1994 the media came out with a story that one of Intel’s Pentium microprocessors had a floating point unit flaw (FPU). This flaw had to do with a math calculation that gave out wrong number after you put in an equation. The story about this flaw came to light after Professor by the name of Thomas Nicely, who was a mathematics professor at Lynchburg collage. Nicely was trying to compute the sum of a reciprocal of a large group of prime numbers on his Pentium based computer. When he checked the results they were different by a large amount from the theoretical values. By running the same test program on a different computer with a 486CPU, he came up with the right numbers this lead him to be able to track down the error to the Pentium itself. After finding the problem Nicely send out an email to Intel describing the problem that he had come across in his test. The email stated that there was a flaw in the Pentium floating point unit (FPU). With no response back from Intel Nicely posted a general notice on the internet asking people to confirm his findings. When the media got wind of this story Nicely did some magazine and T.V interviews about what his test resolute showed him. The flaw in the Pentium flaw was not an isolated incident the flaw was quickly verified by other people around the world in the scientific community, which became referred to as the Pentium FDIV bug. When the story first broke Intel’s initial response was to deny that there was a kind of a problem...

...know that even our machines have flaws in them. That brings me to the idea of Pentium flaw. In my essay I will let you know what the Pentium flaw was and how it is effecting us till this day. In June 1994, while Intel was working on the microprocessor, and they found out there was unit flaw in the Pentium processor. Later on that month, when they were adding the Pentium system to the group of computers, they were unable to determine the other factors as in program errors and motherboard chipsets until October 19 of that year. Three days later he told Intel about the flaw. But Intel was aware of the flaw since May of that year, Professor Thomas Nicely was the one who admitted that they knew about the flaw. It was discovered by Intel during testing of the FPU for its new P6 core, which was first used in the Pentium Pro. 3. On November 7, of that year, the story made a published article in the Electronic Engineering times. The story pretty much said that the glitch was corrected inside of the chip. Steve Smith also said it didn’t even qualify as an error. December 20 of that year, with the people waiting for a response on this, Intel calls in a total recall, which means every microprocessor of Pentium that was flawed was destroyed and replaced.. On January 17, 1995, Intel announces a pre-tax charge of 475 million dollars against their earnings, ostensibly the total cost associated with replacement of...

...hurry. Such was the case with INTEL in 1994. Dr. Thomas R. Nicely, a professor of mathematics at Lynchburg collage in Lynchburg VA was the first person to find the flaw outside of INTEL. Dr. Nicely found this flaw in the floating point unit (numeric co-processor). While performing complicate math equations he found that after the eight digit the numbers are incorrect. At first INTEL tried to keep this a secret until Dr. Nicely sent an email to INTEL on October 30th 1994. He explain how he tested many CPU’s and got the same result. Since INTEL did not inform the general public of this flaw until Dr. Nicely made his email public. I believe INTEL should have let the public know of this flaw as soon as they found it so that the people using them could adjust their mathematical data. Since social media made it easy for everyone to share the information it spread very quickly. Once it spread INTEL’s stock closed at $59.50, down $3.25 for the week. I don’t think INTEL handled it correctly, they should of let the public know as soon as they found out about it. Then INTEL should have issued replacements. INTEL finally did apologize by saying it will replace all flawed Pentiums upon request. It set aside a reserve of $420 million to cover costs. INTEL hires hundreds of customer service employees to deal with customer requests. They also dedicated four fulltime employees to read Internet newsgroups and respond immediately to any postings about Intel or its products. If the same...

...Pentium Flaw From time to time we see stories on the news or on television that have to do with large international companies making mistakes that have effects that shake them to the very foundation on which they were constructed upon. This happened to Intel when they decided to release a microprocessor that they knew had a defect, but went ahead and released it anyway. In June 1944, Intel engineers discovered the flaw in the floating-point math subsection of the new Pentium microprocessor. “Under certain data dependent conditions, low order bits of the result of floating-point division operations would be incorrect, an error that can quickly compound in floating-point operations to much larger errors in subsequent calculations.” (Engineer, 2008) There was a sequence of numbers a user could enter in the OS calculator that showed the error. This rounding error didn’t occur every time, just once every “27,000 years,” or so they thought. In reality, for most typical users, this rounding error would be noticed, on average, every 24 days. After the release, in October of 1994, Dr. Thomas Nicely, a professor of mathematics at Lynchburg College, discovered the bug. Upon the finding of this error, professor Nicely contacted Intel about the issue he discovered in the new microprocessor. After weeks of hearing nothing in return, professor Nicely posted a message on InternetWord. Intel’s reaction to this news was that it was a minor issue and nothing to concern the public with. After...

...Hits Advertorial | By Mark Brooks Dear Opportunistic Investor, I want you to go back in time with me for a minute. I'm going to tell you a story about one of the best performing companies and stocks of the last 50 years, and why we may be on the cusp of history repeating itself.. Just think back to the spring of 1977... Computers were rapidly becoming smaller; a machine that once barely squeezed into a warehouse could now fit onto a desk! And the undisputed king of the mountain was IBM. But your best investment at the time was a company that didn't even sell computers. You know this company as Intel. And of course you also know that Intel supplied one tiny little component for computers -- a component so sophisticated and so essential to manufacturers like IBM (along with Compaq, Hewlett-Packard, Dell, etc.) that every $5,000 invested in Intel stock back then has grown into more than $1 million today. Well, regardless of what all the soundbite jockeys are spouting off lately, there's no doubt who today's computer king is. With the iPod, the iPhone, and the iPad, Apple has taken computers off our desks and put them in the palm of our hand. And just like IBM, they've put themselves in position to dominate this industry for decades. So the obvious question is: “Which Apple-supplier is poised to potentially become the Intel of this generation? Most people don't know this, but The Motley Fool's headquarters is located directly across the street from the U.S. Patent Office...

The media facts were concerned with the entertainment and not the facts; it seemed like each news station was investigating the truth of story, but promoting Zimmerman as a prejudice blood thirsty killer. The Media used bias to depict each individual Travyon and Zimmerman, depending on the news station the media can make anyone seem like the villain in child’s story, the question to ask one’s self is this fair? There have been so many inaccurate information in the new media who can keep track of the assumption and misleading information; some of the information cannot place the role of Zimmerman in the event of the shooting. I believing reading between the lines in any media story or reading a book is essential, if the person and media don’t gather enough Intel it the new article or information is invalid cannot live up as facts, but most individuals don’t read between the media words of facts, not everything is the truth, the truth is whatever sound reasonable in the sake of inaccuracies errors, or bias statement in the media. Long story short, the media will entertain, post valid Intel from time to time, but not all the Intel from the media is true and it’s up to individual to read between the lines and look up the facts for yourself to pass any type of real judgment upon a person, don’t let the media do that for you.

...Case Analysis of Intel Corporation – Leveraging Capabilities for Strategic Renewal Dorothy Thornton Concordia University Portland Technology is a constantly shifting market and Intel is an organization which has adapted their corporate culture and vision to meet the demands of these changes. In the 1980’s Intel’s vision was a performance driven organization focused on new product development with action orientation from the front lines (Bartlett & Nanda, 1994). According to John P Kotter (1995), “A vision says something that clarifies the direction in which an organization needs to move” (p. 63). Intel frequently moved in different organizational directions in the 1980’s to meet the needs of the company. The emerging primary challenge for Intel in the 1990’s was deciding where to make a technological investment in the company. Intel had been successful in the past due to their ability to leapfrog with technology. Intel needed to identify and allocate resources to the products that would allow Intel to remain at the heart of the computer industry. Although Intel had was profitable making microprocessors, they were also investing in other new technology such as the flash chips which had the promise to replace discs and disc drives. Intel needed to determine what technology to invest in to stay ahead of its competitors. This idea is supported in That Used to Be Us which explains American success by staying ahead of the technology curve. Intel’s organizational...

...million. When Intel discovered the flaw, their solution was to keep the information within the company. They did not want to disclose any of the information to the public, because of the negative publicity it would bring to the company. The flaw did not affect all microprocessors, only a very small number of customers. I feel that Intel should have openly acknowledged the problem despite the small number of customers affected. Intel determined if customers were affected by the flaw when they called in to report a problem. They did this by inputting a certain code into their system. Once they identified the problem, Intel would then implement a solution. However, if feel if Intel had openly accepted and informed the clients about the issue, it would have most likely saved them money. Their reputation between the company and their existing clients would have also been protected. Intel’s decision and way of handling the flaw caused a lot of their customers to be very unhappy. If this type of flaw was to be found in a new CPU today, the company would surely fail. With a problem in the floating-point math subsection with an error of approximately sixty-one parts per million, this would cause too many problems for the clients today. Especially considering that Intel declined the opportunity to inform their customers and supply a solution when first reported. I feel that if this were to happen today, many customers would choose a different company, and Intel would have a...
