The Pentium bug was a bug in the Intel P5 Pentium floating point unit. Because of the bug, the processor would send the wrong results for many calculations used in math and science. Intel blamed the problem on a few missing entries in the lookup table used by the company. The error was discovered by Professor Thomas R. Nicely at Lynchburg College on October 24, 1994. The error was rarely encountered by users; however both the flaw and Intel's initial handling of the matter were heavily criticized

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

Unit 5 Analysis1: Pentium Flaw In June 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

discovered and 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

“Pentium microprocessor flaw” There was a Pentium microprocessor flaw identified as the FDIV bug. The bug is a flaw in the point unit. The bug causes the processor to return incorrect results (errors) for many calculations in math and science. Intel claims that it was a problem on a few missing entries in the lookup table used by the company. The flaw was hardly faced by users. It was discovered by Professor Thomas Nicely, a professor of mathematics at Lynchburg College. He noticed the bug when

infrastructure is to implement organization and to help produce and store pertnant information. I noticed that the owners have a dial-up connection which means that most if not all of the club’s business is done on a network. Lisa and Ruben use a Pentium 4 Processor with Windows XP Professional as there software and I would definitley recommend an upgrade since there has not been an upgrade for at least three years. This will allow for better storage and memory of there financial and business-related

Paul Gogue Unit 2 Hyper-Threading NT1110 Introduction: Hyper-threading or HT technology is used by some Intel microprocessor's which allows a single microprocessor to act like two seperate processors to the operating system and the application programs that use it. Hyper-threading enables the "core" processor to execute two concurrent threads of instruction sent by the OS. This simultaneous multi-thread implementation (SMT) is used to improve the parellization of computation, which means
