technology and computers, you come to expect flaws and glitches seeing that these 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

They are as follows: Serial Ports, Parallel Ports, and Game Ports. Serial Ports are male and may contain 9 or 25 pins. The serial port transfers data 1 bit at a time. Parallel ports are female connectors with a total of 25 pins and can transfer data 8 bits at a time. Game ports are female connectors also and contain two rows of pins that

products with numbers to actual names. That is of course not to say that the naming process had anything to do with the fault, it’s simply a handy landmark in remembering the occurrence of the so-called Pentium flaw. The “Pentium flaw” is an inherent calculation flaw that as built into one of the first Pentium microprocessors. It could be described as a very rare division miscalculation that caused an error in output approximately 61 times per billion calculations. It was brought into the mainstream by

NT1110T The Pentium Flaw The Pentium microprocessor flaw is a division error with floating point numbers; it was first discovered by Intel testers in June of 1994. Intel managers said the problem was so small it would not affect very many people, so they carried on with production and told no one outside of the company. They were right that it only affected a few customers, however not disclosing this made Intel look untrustworthy. Within that same month Dr.Nicely tested 486 Pentium machines two

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

The flaw was discovered in June of 1994. The people who discovered it didn’t think it would affect very many people so they didn’t tell anyone and kept it a secret. Then on October 19 the flaw was discovered by Dr. Nicely, not affiliated with Intel. He found that the flaw was coming from the Pentium processor. After contacting Intel they did nothing about it so he began to spread the word. The nature of the flaw was in the floating-point math subsection of the Pentium microprocessor. Under certain

The Flaw in the Intel Pentium Chip I In late 1994, the media began to report that there was a flaw in the new Pentium microprocessor produced by Intel. A flaw in the Pentium was especially significant since at that time it was the microprocessor used in 80% of the personal computers produced worldwide. Apparently, flaws in a complicated integrated circuit such as the Pentium are not uncommon. Most of these flaws cannot be detected by the user and do not affect the operation of the computer

Valeras-NT1110 Friday, April 18, 2014 Unit 5 Analysis 1: Pentium Flaw Pentium purpose and functions was that it was a microprocessor in the CPU and the chip included a floating point unit FPU also known as a math coprocessor. Unlike the old Intel CPUs that did arithmetic using integers, this was a program that used floating point number. The Pentium chips have the instructions built into the chip which was in the FPUs. It made the Pentium must faster for intense numerical calculations. It’s was

Case Analysis: The Intel Pentium Chip Controversy (A) Immediate Issue: As Andrew Grove, during my meeting of December 17,1994 with my internal team, Should I approve replacing the defective Intel chips of all concerned users with no-question asked? Also, should we also pay for the labor and other incidental costs? How should we integrate our decision into our financial books? Basic Issues: • Negative Publicity: Since Oct 30th, we have encountered a self-propelled negative publicity campaign

Pentium Microprocessor Flaw The Pentium Microprocessor Flaw was in the floating point math section. The most famous example is the case 4195835/3145727. The division results were off by approximately sixty-one parts per million. The way this issue was discovered was by a math professor at Lynchburg college by the name of, Thomas Nicely, this college was located in Virginia. He discovered this flaw in summer/fall of 1994. While he was computing the sum of the reciprocals of a large collection of
