    GENERAL FEATURES __________________________________ PROCESSOR The 80486 microprocessor is the state-of-art microprocessor which merges many innovative features on a single chip for advanced applications and operating systems. Fabricating with the l um process, this CPU consists of more than one million transistors. With such high density, this CPU incorporates as many as new features make...
  • Page 14 GENERAL FEATURES __________________________________ The internal cache memory is a 8K bytes, 16 bytes line size, four-way set associative configuration. The hit rate of this configuration in a multitasking and multi-processor environment is much higher than 32K bytes two-way set associative external cache. Bus snooping feature keeps the cache memory consistent with the main memory.
  • Page 15 GENERAL FEATURES __________________________________ By eliminating the access to external bus, operations with the internal cache can be completed in a single cycle. 80386 at least needs two cycles for an operation. To further increase the rate of data transfer inside the CPU, the internal bus of the cache memory is increased to 128 bits, which is four times of the external bus.
  • Page 16 GENERAL FEATURES __________________________________ Internal memory management unit provides a flexible addressing scheme for the next generation operation system. Multitasking, concurrent operation and manipulating huge data base can be accomplished with excellent performance. Paging mechanism is employed allow powerful operating system implement virtual memory.

  • Page 17: External Cache

    GENERAL FEATURES __________________________________ EXTERNAL CACHE Although 80486 comes with 8 KB internal cache memory, there are many applications, such as those found in multi-user, multitasking, or multi bus master environments, the internal cache memory were found insufficient and cause system bottleneck. Thus, an external cache memory using an interleaved write back cache designed in the DRAGON EISA board to support...

Alternately, a cache memory reduces the CPU's utilisation onto the DRAM. The CPU is only put into wait state when it has to utilize the DRAM to exchange information between the cache and DRAM while other bus master is using it.
  • Page 19 GENERAL FEATURES __________________________________ only perform to the fast cache memory and only a fraction of dirty write data get to put back to DRAM. The low DRAM utilisation means the availability of DRAM to other bus master has been improved. In an EISA system, where more than one bus master device are often installed, the write-back cache design can improve the overall system performance.

  • Page 21 GENERAL FEATURES __________________________________ The DRAM refresh logic is redesigned to improve the overall system performance and power consumption. In the original PC/AT design, the DRAM refresh operation will suspend the CPU operation because it has to access the DRAM. In high speed system like DRAGON EISA board, the CPU indeed can process a large amount of data during the DRAM refresh period.

    Appendix B EISA Configuration Utility _______________________________ EISA SYSTEM CONFIGURATION One of advantage of EISA over ISA is its ability of automatem system configuration to resolve conflict of resources (such as I/O ports, memory, interrupt lines, DMA channels) among system board and add on cards. This means an EISA system can be designed with no DIP switch and jumpers.
