The National IMP-4 (originally National GPC/P) was a family of multi-chip 4-bit bit-slice microprocessor developed by National Semiconductor and introduced in 1973. Units could be combined to implement systems with 4 to 32-bit words. The IMP-8 and IMP-16 families were made using the IMP-4 logic. The IMP-4 had 2 chips: a control unit and an ALU, some systems used the RALU with custom control circuitry. The RALU was the first bit-slice microprocessor - predating both the 3000 and the am2900.
2nd sources
Rockwel was the only 2nd source for the IMP-4 series. Some USSR clones are known to exist.
