D.2.1 CPU32+ Core
The CPU32+ core is a CPU32 that has been modified to connect directly to the 32-bit IMB
and apply the larger bus width. Although the original CPU32 core had a 32-bit internal data
path and 32-bit arithmetic hardware, its interface to the IMB was 16 bits. The CPU32+ core
can operate on 32-bit external operands with one bus cycle. This allows the CPU32+ core
to fetch a long-word instruction in one bus cycle and to fetch two word-length instructions in
one bus cycle, filling the internal instruction queue more quickly. The CPU32+ core can also
read and write 32-bits of data in one bus cycle.
Although the CPU32+ instruction timings are improved, its instruction set is identical to that
of the CPU32. It will also execute the entire M68000 instruction set. It contains the same
background debug mode (BDM) features as the CPU32. No new compilers, assemblers, or
other software support tools need be implemented for the CPU32+; standard CPU32 tools
can be used.
The CPU32+ delivers approximately 4.5 MIPS at 25 MHz, based on the standard (accepted)
assumption that a 10-MHz M68000 delivers 1 VAX MIPS. If an application requires more
