摘要:
An arithmetic logic and shifting device is disclosed and includes an arithmetic logic unit that has a first input to receive a first operand from a first register port, a second input to receive a second operand from a second register port, and an output to selectively provide a memory address to a memory unit in a first mode of operation and to selectively provide an arithmetic output in a second mode of operation. Further, the arithmetic logic and shifting device includes a programmable shifter device that has a first input to receive data from the memory unit, a second input to receive the arithmetic output, a third input to receive an operation code of a computer execution instruction, and a shifted output to provide shifted data.
