80188EB 16-bit microprocessor

The 80188EB is a powerful 16-bit microprocessor core, executes instruction
list compatible with 80188EB microprocessor. The 80188EB core has a broad
set of integrated peripherals, which helps reduce system development time and
cost and is compatible with wide range of compilers and debuggers. The
design along with multiple peripherals can be fit into single FPGA.
