Description:Intel 80188 microprocessor is an enhanced version
of Intel 8088 processor. Like the 8088, the 80188
has 16-bit internal architecture and 8-bit
external data bus. The 80188 integrates many
system components into one chip, implements 7 new
instructions and adds new operand types to three
existing 8088 instructions. With the exception of
integrated components, the 80188 microprocessor
is not very different from the 8088, and, because
of this, it may be considered as an embedded
version of the 8088. The Intel 80188 didn't even
have its own version of co-processor and worked
with Intel 8087. Not much used in computers, the
Intel 80188 was successful in embedded processor
market. In fact, the processor was so successful,
that many different versions of the processor
were introduced by Intel and other second-source
companies since 1982 - These have just recently
(2001) stopped being made, though there are still
some being used in an ASIC implementation
