Abstract

See full text

A single-chip microprocessor device of the MOS/LSI type contains an ALU, several interal busses, a number of address/data registers, and an instruction register with associated control decode or microcontrol generator circuitry. The device communicates with external memory and peripherals by a bidirectional multiplexed address/data bus and a number of control lines. The ALU, registers and busses along with the control ROM are constructed in an interrelated layout whereby minimum space is needed on the chip. Like bits in all registers and the ALU are aligned and in a regular pattern. The busses are metal lines overlying each of the strips of ALU/register bits. Controls are polysilicon lines perpendicular to the busses and aligned with columns of the control ROM. The control ROM is an array of rows and columns of potential MOS transistors, compressed by eliminating column lines which contain no transistors. The number of bits per column is a minimum to enchance compressability producing a wide configuration (long row lines) which allows the columns for control signals to align with the part of the ALU/register strip where the signal is to be used.
