**82498/493 Cache Controller / Cache RAM (for P54 Pentium) <Nov94
***Notes:...
***Info:
The 82498 Cache Controller and multiple 82493 Cache SRAMs combine with
the Pentium processor (735/90, 815/100) and future Pentium Processors
to form a CPU Cache chip set designed for high performance servers and
function-rich desktops. The high-speed interconnect between the CPU
and cache components has been optimized to provide zero-wait state
operation. This CPU Cache chip set is fully compatible with existing
software, and has new data integrity features for mission critical
applications.
The 82498 Cache Controller implements the MESI write-back protocol for
full multiprocessing support. Dual ported buffers and registers allow
the 82498 to concurrently handle CPU bus, memory bus, and internal
cache operation for maximum performance.
The 82493 is a customized high-performance SRAM that supports 64-, and
128-bit wide memory bus widths, 32-, and 64-byte line sizes, and
optional sectoring. The data path between the CPU bus and memory bus
is separated by the 82493, allowing the CPU bus to handshake
synchronously, asynchronously, or with a strobed protocol, and
allowing concurrent CPU bus and memory bus operations.
