IMP-00A

National Semiconductor

Monolithic MOS / LSI circuit utilizing standard P-channel, enhancement mode, silicon gate technology; it provides a 4-bit slice of the register and arithmetic portion of a general purpose controller / processor; RALU's may be stacked in parallel for longer word lengths (up to 32-bit); The RALU has been designed to be used with other members of National's IMP family (in particular the CROM) to form a complete processor; the RALU operates on +5V and -12V supplies with 4-phase, non overlapping clocks; applications: general purpose processor, machine tool controlers, small business machines, terminal controllers, test system and instrument control, traffic controller

IMP-16A/522J

National Semiconductor

Monolithic MOS / LSI circuit utilizing standard P-channel, enhancement mode, silicon gate technology; it provides read only microprogram storage and control logic and is designed for use with the register and arithmetic logic unit; the CROM provides storage for one-hundred microinstructions of 23 bits each; one CROM may be used with 1 to 8 RALU's to implement systems with 4 to 32-bit word lenghts; multiple CROMs may be used to provide expanded capability; CROMs are available with standard 8 and 16-bit instruction sets; the CROM operates on +5V and -12V supplies with 4-phase, non overlapping clocks; applications: custom instruction sets; custom application control programs; standard IMP instruction sets; control of 4 to 32-bit microprocessors when used with register and arithmetic logic unit
