Microprocessor with strip layout of busses, ALU and registers |
摘要 |
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. A 16-bit device is shown as an example. The ALU and registers are laid out on the chip in a regular pattern with like bits in all registers and ALU aligned, and the busses are parallel metal strips overlying each of the strips of ALU/register bits. Controls are polysilicon lines perpendicular to the busses. A very dense layout results, saving space on the chip.
