In 1981 AMD announced the AM29116 microprogrammed 16-bit processor.  It was made on a 2 micron process and contained 2500 effective gates (~14,000 transistors, 50mm2 die area).  Max speed was 10 MHz.

The Am29116 is technically a bit-slice processor, like AMD’s wildly successful 2901 processor but adds a bit more functionality including instruction for bit manipulation, CRC generation, as well as a barrel shifter and an on chip scratch pad RAM (32x16bit).  It has an accumulator, ALU, status register, and instruction latching/decoding for the 167 instructions.  What the 29116 lacks is a PC (Program Counter).  Program sequencing is handed by external logic, either custom, or using AMD 29112 microprogram sequencers.  It is the job of the sequencer to feed instructions to the 291116, handled jumps, calls, returns, and memory accesses.  This puts the 29116 somewhere between the basic 2901 and a full featured processor like the Z8000.

The AM29116DC was available on the commercial market in 1982. This example in our collection is a special cased presentation version of the microprocessor which is marked 'AM29116DC The World's Fastest Micro Processor © 1981 AMD'.
