AMD Am2900 is a family of 4-bit bipolar logic devices which function together as a bit-slice processor. The Am2901 and Am2903 arithmetic-logic units are the core of the series, with other tasks being handled by about 50 different Am29XX devices. The Am2900 family was used in the design of various DEC and Data General minicomputers, and is widely regarded as the most successful bit-slice architecture.
