Abstract
A computer instruction execution unit includes different execution paths for different categories of instructions. Different execution paths share circuitry. The slower execution paths are pipelined. In some embodiments, all execution paths are pipelined. Fast instructions are executed by a fast execution path. Slower instructions are executed by a slower execution path. Faster instructions immediately following the slower instruction are also executed by the slower execution path not to block the shared circuitry. Consequently, the throughput is increased and the average instruction execution latency is reduced. When a sufficient number of clock cycles occur with no instructions started, subsequent fast instructions are executed by the fast execution path.
