Pentium

The Pentium processor was invented by the Intel Corporation in 1993 and it is a widely used in personal computer. This processor is also called Pentium 1, P5 otherwise Intel 80586, because it was the 5th generation of Intel microprocessors. The Pentium 1 is the first microprocessor in the Pentium series. The features of this Pentium1 processor mainly include; 32-bit processing, 16 KB – 32KB L1 cache, FSB (Fast serial bus) up to 66 MHz and base CLK speed ranges from 66HZ to 300MHZ. There are different Pentium microprocessors available in addition to the Pentium I like Pentium II, III, IV, M, and dual core. This article discusses an overview of a Pentium processor definition – working with applicatiThe original Pentium is an extremely modest design by today's standards, and when it was introduced in 1993 it wasn't exactly a blockbuster by the standards of its RISC contemporaries, either. While its superscalar design (Intel's first) certainly improved on the performance of its predecessor, the 486, the main thing that the Pentium had going for it was x86 compatibility. In fact, Intel's decision to make enormous sacrifices of performance, power consumption, and cost for the sake of maintaining the Pentium's backwards compatibility with legacy x86 code was probably the most strategically-important decision that the company has ever made.The choice to continue along the x86 path inflicted some serious short- and medium-term pain on Intel, and a certain amount of long-term pain on the industry as a whole (how much pain depends on who you talk to), but as we'll see the negative impact of this critical move has gradually lessened over time.The Pentium's two-issue superscalar architecture was fairly straightforward. It had two five-stage integer pipelines, which Intel designated U and V, and one six-stage floating-point pipeline. The chip's front-end could do dynamic branch prediction, but as we'll learn in a moment most of its front-end resources were spent on maintaining backwards compatibility with the x86 architecture.ons.
