Cache overview

• A special feature of the &80480 mainboards is a built-in direct mapped cache controller with write-back operation and support for 64KB to 1024K5 Cache memory With 16 bytes cache line size.
• The cache capabilities of the 80486 mainboards significantly improve the performance of your software applications.
• Cache works by copying your most recently accessed data and placing it in an area of high speed memory called SRAM.
• Cache SRAM is positioned between the main memory DRAM and then from SRAM to the CPU. 1The CPU then accesses data in and out of the SRAM at a very high speed, allowing your applications to un much faster.
• The cache capabilities of the 80486 mainboards significantly improve the performance of your software applications.
• Cache works by copying your most recently accessed data and placing it in an area of high speed memory called SRAM.
• Cache SRAM is positioned between main memory DRAM and then from SRAM to the CPU. The CPU then accesses data in and out of the SRAM at a very high spced, allowing your applications to run much faster.
• Since most program executions are sequential and repetitive. the likelihood is great that the CPU will find data already stored in cache. If the data is already in cache, a cache hit results. If the CPU must go to main memory DRAM or your floppy disk to access the data, then a cache miss occurs.
• The 80486 mainboard’s built-in cache controller offers several teatures that enhance system performance during cache hit and cache miss cycles. A Page DRAM memory enhances performance during read miss cycles.

Hardware Configuration

Before you install the 80486 mainboard into the system chassis, you may find it convenient to first configure the mainboard’s hardware. This chapter describes how to set the mainboard jumpers for cache memory and display type, and how to install a math coprocessor and memory modules.

Power Precautions

• Before you begin configuration, make sure you are working with an unplugged mainboard. Many components are powered by low-voltage current, but there still may be a dangerous electric current coming from the leads and power supply. You should take the following precautions:
• Turn off the mainboard, and unplug the power cord before you begin.
• Unplug all cables that connect the mainboard to any external devices.

Jumper Settings

• You configure hardware options by setting jumper switches on the mainboard. Jumper switches are rows of small pins on the mainboard that you can set by using a Jumper cap.

Set a jumper switch as follows:

• Short a jumper switch by placing the plastic jumper cap over two pins of the jumper.

• Open a jumper switch by removing the jumper cap
  Note : When you open ajumper, attach the plastic jumper

• Cap to one of the pins so you won’t lose it.

Symbols:

For setting Multi-pin jJumpers, the symbols below are used:

• 1-2 means to Short with a jumper cap in pin 1 and pin 2
• 2-3 means to Short with a jumper cap in pin 2 and pin 3
