MICROPROCESSOR — The VMIVME-7588 brings Intel® Pentium processor power to VMEbus, offering processor speeds from 133 to 233 MHz. The Pentium processor has 32-bit addressing and a 64-bit data bus. Its superscalar architecture includes two pipelined integer units and a pipelined floating-point unit, allowing two instructions to be executed per clock cycle. A dynamic branch prediction unit and separate instruction and data caches also increase the Pentium processor’s performance.

EXTERNAL (L2) CACHE MEMORY — The VMIVME-7588 complements the Pentium processor with 512 Kbyte of external cache memory. Near-zero wait state operation of the Pentium processor is ensured by the use of synchronous burst static RAM with the Intel Triton II chipset. 

DRAM MEMORY — The VMIVME-7588 accepts two 72-pin SIMM DRAM modules with or without parity for a maximum memory capacity of 256 Mbyte. The on-board DRAM is dual ported to the VMEbus.
