**82497/492 Cache Controller / Cache RAM (for P54 Pentium) <Nov94
***Notes:...
***Info:
The 82497 Cache Controller and multiple 82492 Cache SRAMs combine with
the Pentium processor (735\90, 810\100) 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 82497 cache controller implements the MESI write-back protocol for
full multiprocessing support. Dual ported buffers and registers allow
the 82497 to concurrently handle CPU bus, memory bus, and internal
cache operation for maximum performance.
The 82492 is a customized high-performance SRAM that supports 32-,
64-, 128-bit wide memory bus widths, 16-, 32-, and 64-byte line sizes,
and optional sectoring. The data path between the CPU bus and memory
bus is separated by the 82492, allowing the CPU bus to handshake
synchronously, asynchronously, or with a strobed protocol, and
allowing concurrent CPU bus and memory bus operations.
