What was offered by Intel in 1997 to their users to solve the problem found in the processor?
Intel offered to replace processors to users who could prove that they were affected. However, although most independent estimates found that the bug would have a very limited impact on most users, it caused significant negative press for the company.
What causes the Intel Pentium processor to divide some floating points incorrectly?
The Pentium FDIV bug is a hardware bug affecting the floating-point unit (FPU) of the early Intel Pentium processors. Because of the bug, the processor would return incorrect binary floating point results when dividing certain pairs of high-precision numbers. The bug was discovered in 1994 by Thomas R.
What was Intel’s original proposal on the flawed chips?
Intel’s plan was to release the chip and just fix the flaw on the future processors. This action would make Intel a great deal of profit, no one would find out, and once the processors sold out, the fixed ones would be released and everything would be normal.
Why was the Intel Pentium floating-point bug such a big issue?
The processor floating-point divide problem was caused by a subtle but specific circuit-design error; the flaw was easily corrected with changes to masks in the next regular production revision of the chip, in 1994.
When did Intel stop making Pentium processors?
2006
With the 2006 introduction of the Intel Core brand as the company’s new flagship line of processors, the Pentium series was to be discontinued.
How many Pentium processors are there?
“P54CS” (0.35 μm)

What happened to Pentium processors?
In 2006, the name briefly disappeared from Intel’s technology roadmaps, only to re-emerge in 2007. In 1998, Intel introduced the Celeron brand for low-priced microprocessors. With the 2006 introduction of the Intel Core brand as the company’s new flagship line of processors, the Pentium series was to be discontinued.
Are Pentium processors good?
Newer Pentium models, such as those launched in 2017 onwards, are becoming more common on laptops costing between £250 and £300. These chips are power-efficient, meaning they’re great when you want a laptop with a long battery life. They’re perfectly usable for web browsing and basic office work.
Who invented Pentium microprocessor?
Vinod Dham
In many ways, Vinod Dham, 60, redefined the way people looked at semiconductors that powered computers by leading a group of engineers at Intel in 1993 to develop the Pentium — Intel’s first microprocessor with a name.
What are the features of Pentium microprocessor?
Features of Pentium Processor are as follows:
- 64 bit data bus.
- 8 bytes of data information can be transferred to and from memory in a single bus cycle.
- Supports burst read and burst write back cycles.
- Supports pipelining.
- Instruction cache.
- 8 KB of dedicated instruction cache.
What is the Pentium microprocessor flaw?
In Intel: Pentium microprocessor …mistake was the so-called “Pentium flaw,” in which an obscure segment among the Pentium CPU’s 3.1 million transistors performed division incorrectly. Company engineers discovered the problem after the product’s release in 1993 but decided to keep quiet and fix the problem in updates to the chip.
What is the Intel FPU flaw and how was it discovered?
The flaw was discovered by Intel during testing of the FPU for its new P6 core, which was first used in the Pentium Pro.
What happened to the Intel Pentium microprocessor?
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.
How do you assign a Pentium flaw assignment?
Pentium Flaw Assignment Requirements 1. Search the Internet for information about the Pentium microprocessor flaw, using keywords such as “Pentium microprocessor flaw. ” 2. Determine the nature of the Pentium flaw, how it was discovered, when it was discovered, and Intel’s response to the flaw.
