This part exists now, in internal engineering samples.  The 25 MHz part 
executes at 12.5 Mips and there will soon be a 33 MHz. part.  It features
2K of on-chip instruction and data caches, and a seven stage pipeline
with branch prediction.

The V80 is a successor to the V60 and V70, and is essentially a faster
part with this same architecture.  Like these earlier parts, it supports
demand paged virtual memory through an internal MMU, internal floating
point, support for fault tolerance, and a V30 (i.e., 8086) emulation mode.

These 32-bit V-series processors have some popularity in Japan, but
like these earlier parts, the V80 may not be aggressively promoted 
for the U.S. market (this is my own perception, not a policy statement 
by NEC).  In any event, we have at present very little literature available
for the device.  It is mentioned in our data book, but little detail is
provided.  There was an article about the V80 in the February 13, 1989
issue of EE Times.
