Processor and Secondary Cache
The PowerMate Pro150 uses a 150-MHz Pentium processor with internal speed of 150
MHz and external speed of 60 MHz:
Each processor has 16 KB of write-back primary cache and a math coprocessor. The 16 KB
primary cache provides 8 KB for instructions and 8 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 256 KB of secondary write-back cache incorporated into the processor.
The processor is compatible with 8-, 16-, and 32-bit software written for the Intel386™,
Intel486™, and Pentium processors. The Pentium processor is mounted into a socket-8
zero insertion force (ZIF) socket. The socket provides an upgrade path to the next
generation processor.
