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

“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

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

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

Explain each of the Generation of Processor. P1 (086) Processor - Intel introduced the 8086 back in June 1978. The 8086 was one of the first 16-bit processor chips on the market; at the time, virtually all other processors were 8-bit designs. The 8086 had 16-bit internal registers and could run a new class of software using 16- bit instructions. [pic][pic] P2 (286) Processor - In 1982, Intel introduced the Intel 80286 processor, normally abbreviated as 286. The first CPU behind the

day as new technologies are being invented. The future of microprocessors is bright. To know how microprocessors started lets go back to the first microprocessor invented, the 4004 by Intel. 4004 was the first integrated microprocessor. As like all the inventions it has improved by a lot since its invention. “Intel 4004 introduced in 1971. The 4004 was not very powerful -- all it could do was add and subtract, and it could only do that 4 bits at a time. But it was amazing that everything was on

This activity provides insight into the mind of two iconic leadership figures, Michael Dell, founder and CEO of Dell, Inc., and Andy Grove, cofounder and former CEO of Intel, Inc. Michael Dell is considered a modern maverick of leadership. From the inception of his company he focused on providing his customers’ products based on their specific needs and requirements at the lowest price possible. He was not a big fan
