Abstract
A multi-function ALU (arithmetic/logic unit) for use in digital data processing facilitates the execution of instructions in parallel, thereby enhancing processor performance. The proposed apparatus reduces the instruction execution latency that results from data dependency hazards in a pipelined machine. This latency reduction is accomplished by collapsing the interlocks due to these hazards. The proposed apparatus achieves performance improvement while maintaining compatibility with previous implementations designed using an identical architecture.
