Processor
The PowerMate series of computers use the following Pentium processors:
PowerMate P2166M — 166-MHz MMX processor with internal speed of
166 MHz and external speed of 66 MHz.
PowerMate P2200M — 200-MHz MMX processor with internal speed of
200 MHz and external speed of 66 MHz.
Each processor has 32 KB of write-back primary cache and a math coprocessor. The 32 KB
primary cache provides 16 KB for instructions and 16 KB for data.
The processor is an advanced pipelined 32-bit addressing, 64-bit data processor designed to
optimize multitasking operating systems. The 64-bit registers and data paths support 64-bit
addresses and data types.
To use the Pentium processor’s power, the system features an optimized 64-bit memory
interface and complementary asynchronous pipelined 256-KB secondary cache.
The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386™,
Intel486™, and Pentium processors.
To accommodate future technologies and work requirements, the Pentium processor comes
in a 320-pin zero insertion force (ZIF) socket. The socket provides an upgrade path to the
next generation processor.
Secondary Cache
The system board contains 256 KB of pipeline-burst, external to the processor. Cache
allows data to be sent or received from cache with one wait state burst. Cache memory
improves read performance by holding copies of code and data that are frequently requested
from the system memory by the processor. Cache memory is not considered part of the
expansion memory.
