The National IMP-16 is a family of multi-chip 16-bit bit-slice microprocessor developed by National semiconductor and introduced in 1973. The chips were made using PMOS technology. Like the IMP-8, the IMP-16 was designed using 4 IMP-4 4-bit bit-slice logic units and a single control unit. The IMP-16 was later superseded by the PACE and later by the INS8900.
