The first such family is the Am2900 series of integrated circuits (ICs) created in 1975 designed in bit-slice topology so they could be used as modular components each representing a different aspect of a computer control unit (CCU).
The AMD Am29xxx series of chips are high performance processors and system building-block devices.
The Am29000 was a Berkeley RISC, register window design similar to the Sun SPARC.
The Am29200 family are processors intended for the high-end microcontroller market.
The Am29800 family are bus interface chips and bit-slice support devices notable for in-circuit testing capability.
