ABSTRACT:
A clocked instruction flow is managed subject to issue and fetch constraints through a plurality of instruction latches which receive instructions from selected memory locations. By checking the number of instructions fetched and issued, the fetch program counter is adjusted responsive to the status of selected state variables indicating instructions issued and fetched. The instruction latches are fully scheduled from cycle to cycle with instructions, by fetching instructions in accordance with a fetch program counter.
