Cache Configuration
The G486-EVA system board can be configured to two
different cache sizes: 128KB and 256KB. 128KB of
cache memory is the default size. Either four or eight
32K x 8 (20ns) SRAM chips are used for cache depend-
ing on the size of cache desired. Regardless of the
amount of cache memory installed, one 32K x 8 (20ns)
SRAM is needed for tag RAM to store the cacheable
addresses. The locations of the SRAM sockets on the
system board is shown on the next page.
