Motorola 56000
The Motorola DSP56000 (also known as 56K) is a family of digital signal processor (DSP) chips produced by Motorola Semiconductor (later Freescale Semiconductor and then NXP) starting in 1986 with later models still being produced in the 2020s. The 56k series was intended mainly for signal processing in embedded systems, but was also used in a number of early computers, including the NeXT, Atari Falcon030 and SGI Indigo workstations, all using the 56001. Upgraded 56k versions are still used today in audio equipment, radar systems, communications devices (like mobile phones) and various other embedded DSP applications. The 56000 was also used as the basis for the updated 96000, which was not commercially successful.
