Intel engineers discovered a flaw in the floating-point math subsection of the 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. Intel corrected the error in a future chip revision, but nonetheless declined to disclose it. Dr. Thomas Nicely, Professor of Mathematics at Lynchburg College

in a 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

INTEL CASE - Explain Intel's strategies and their evolution in time. - Analyze critically Intel's strategies. Bob, Gordon and Andrew established in California in 1968 a world famous company: Intel. At the beginning, this company produced semiconductor memory chips; however, as we will explain during this paper Intel’s production shifted into other fields. The main strategy Intel had was innovation the design of the product and being the first ones to achieve the market with the newest

the calculation was 4,195,579” (Crothers, 1994). Intel originally denied that there was even a flaw. Only after it become clear to the public that there was actually a flaw, did they acknowledge there was a flaw but it was a small and insignificant. They would only replace it if the user could prove that they needed an unflawed processor. This caused IBM to immediately stop all sales of their computers that featured the Pentium chip, forcing Intel to agree to replace all flawed microprocessors with

tracked the error himself on the Pentium itself. After not getting a straight forward response to his initial queries to Intel and after checking his facts multiple times, he nicely posted a general notice on the internet asking others to see if they came up with the same results as he did. After that post he got a couple magazine interviews and shortly after even CNN interviewed him. Intel publicly announced that, “an error is only likely to occur [about] once in nine billion random floating point divides

The Pentium Flaw Unit 5 Analasyis 1 The Pentium flaw is that on certain input data, the floating point divide instructions on the Pentium processor produce inaccurate results. Intel quoted an error rate of about 1 in 8.77*10^9 random divisions. The exact frequency depends on the type and precision of the operands; single-precision reciprocals, for example, are always returned correctly. (Nicely, 2011) This was first reported by Professor Thomas Nicely in October of 1994 by computing the

devices are manmade. One of the biggest computer flaws in computer history was the “Pentium Microprocessor flaw”; this was a bug in the Intel P5 Pentium floating point that caused the processor to return incorrect results for many calculations used in math and science. This bug was blamed on the fact that there were a few missing entries in the lookup table used by Intel. This flaw was exposed by Professor Thomas R. Nicely, who was a professor at Lynchburg College in Virginia. Nicely discovered this

Computer Structure and Logic Unit 5 Analysis THE FLAW IN THE INTEL PROCESSOR CHIP Since computer evolution, various computer companies have made their marks on the shores of revolutionizing computer as we know it. Hence, Intel, one of the world’s computer company giants, is not an exception to the zeal of making computers more efficient as the world evolves with time. However in 1994, Intel was hit by a major setback related to a flaw in its P5 Pentium Floating Point Unit
