Computer Support For Pentium Based Computer

Pentium P5, the fifth generation of Intel chips was derived from the 80486 processor. This feature x86 superscalar architecture reduces the latency of address calculation, the processing unit faster floating, two pipelines full, 64-bit data bus, separate code and data caches. The latest Pentium with MMX technology was the mid-1990s, the integrated processor called a Pentium MMX. MMX, and large caches were implemented Pentium MMX. Pentium-rivals are AMD K5, Cyrix 6x86, Motorola 68060, PowerPC 601, Winchip C6, Rise MP6, NexGen Nx586, etc. Since the market share of this revolutionary processor more than 80%, network support for them is also widespread.

Characteristics of the Pentium P5

Compared to the 486-processors, the performance has improved significantly the Pentium. The execution speed of Pentium is almost twice the execution speed of 486 processors. It can be run more than 100 million instructions per second. With 75MHz clock, so the execution speed to over 125 million instructions per second. With the improvement as long as the PC need high quality support for Pentium P5 to solve problems.

Bus 64 data bits

The width of the Pentium data bus is 64 bits, double the 80 486 data bus. This feature doubles the bandwidth for reading and writing to memory. To store the code in the cache memory is also faster. Sometimes the data in tightly closed when two data paths are short, the computer will start to not work properly. To diagnose network problems such support could be very useful.

Superscalar architecture

Superscalar technology has been implemented in a Pentium processor for the first time in the history of microprocessor technology. This is the first superscalar processor. Superscalar technology uses two data paths or run pipes up to 2 instructions per clock cycle 1. The main line is designed for any kind of instructions, while the secondary pipeline may seek only simple instructions. To get the maximum benefit from double the pipeline, the optimized code to implement instructions to both pipelines are executed simultaneously. Technical support can be very useful in optimizing code.

Faster memory bus

Pentium processors in the system of control over the bus speed of 60MHz to 66MHz run, while 80 486 processors are used to drive the bus at 33MHz. So the performance is greatly enhanced in the Pentium. Pipelined burst cache is another feature that enables faster memory access.

Integrated Power Management

User management system is implemented in Pentium, regulate the operation of power management. This mode is optional in the 80486 processor.

Floating Point Unit

The floating point unit of the Pentium is much faster compared to the 80486th Some commands, such floating FMUL are 15 times faster. FXCH ST (x) a declaration could be parallel to one arithmetic or Load / Store instruction to execute FPU.

Code and data cache

Split Level 1 cache is used in Pentium. Memory is the data cache and 8KB cache code assigned to each. Separation of code and data cache reduces read and write conflicts. Since both are associative caches of the two channels, the access time and cost of implementation is reduced.

Microcode

The two pipelines can be used simultaneously with the Pentium microcode to allow the automatic repetition of instructions that perform iteration in each clock cycle. 80486 processor in an iteration in the three cycles is performed.

Hardware-based multiplier

the execution time of instructions MUL and IMUL is significantly reduced.

Network support for Pentium

some errors were discovered after Pentium was introduced in the market. Some floating-point divisions gave incorrect results. Some malicious programs could lead the system to crash, without special privileges. Some versions of Pentium-based computers with a high heat. To solve all the problems, computer support could be very effective. Many vendors support network are made solutions to Pentium PC.
