Abstract
A microprocessor having M parallel pipelines and N arithmetic logic units, where N is less than M. A single instruction fetch stage fetches multi-stage instructions, and a single instruction decoder provides a parallel set of three instructions to the three pipelines. The two ALUs are dynamically connected to two of the pipelines having instructions requiring an ALU, while the third pipeline executes an instruction in parallel that does not require an ALU. The third pipeline may have a move unit connected to it.
