Abstract
A digital operation unit includes a dual-port arithmetic logic unit (ALU) receiving data from a data bus and a plurality of registers selectively storing ALU computations. The digital operation unit also including a first set of switches connected between the ALU the registers, a second set of switches connected between the registers and one of the dual ALU input ports, and a third set of switches connected in parallel with the second between the registers and the data bus.
Claims6
A digital operation unit comprising:
- an arithmetic logic unit (ALU) receiving data from a data bus via first and second ALU input ports, and generating results of arithmetic and logical operations of the data;
- a plurality of registers storing the results;
- a plurality of first switches connected between the ALU and the plurality of registers, and controlling transmission of data between the ALU and the plurality of registers;
- a plurality of second switches connected between the plurality of registers and the first ALU input port, and controlling transmission of data between the plurality of registers and the first ALU input port;
- and,
- a plurality of third switches connected in parallel with the plurality of second switches between the plurality of registers and the data bus, and controlling transmission of data between the plurality of registers and the data bus.
