6-5 Technical Information
I Overview
The PEM-2530 incorporates the Intel 80386 microprocessor as the
basis of its 32-bit architecture. The 25MHz speed of the microproces-
sor, coupled with the performance benefits of the 32-bii architecture,
provide exceptional performance well beyond the reach of most per-
sonal computer products currently using 16bit architectures. A feature
of primary importance is the PEM-2530’s compatibility with existing
software and hardware products designed for the 8088 and 80286
members of the Intel microprocessor family.
The PEM-2530 mainboard uses a 25MHz 32-bit DRAM subsystem and
a 32-bit memory expansion bus for maximum bandwidth in the memory
subsystem. This architecture is critical to the PEM-2530’s perfor-
mance, given the high bandwidth requirements and 32-bit optimum of
the instruction prefetch of the 60366. The 8MHz, 8 and 16-bit expan-
sion buses provide full compatibility with industry-standard hardware
expansion products designed for 8MHz 80286-based personal com-
puters.
