Processor

The PowerMate Ve series of computers use the following Pentium processors:
n
PowerMate Ve75 — 75-MHz processor with internal speed of 75 MHz and
external speed of 50 MHz.
n
PowerMate Ve100 — 100-MHz processor with internal speed of 100 MHz and
external speed of 66 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.
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.
