HARDWARE CONTROL OF INSTRUCTION OPERANDS IN A PROCESSOR

摘要

An apparatus generally having a first circuit, a second circuit and a third circuit is disclosed. The first circuit may have a counter and may be configured to adjust at least one control signal in response to a current value of the counter. The first circuit may be implemented only in hardware. The counter generally counts a number of loops in which a plurality of instructions are executed. The second circuit may be configured to set the counter to an initial value. The third circuit may be configured to execute the instructions using a plurality of data items as a plurality of operands such that at least two of the instructions use different ones of the operands. The data items may be routed to the third circuit in response to the control signal. The apparatus generally forms a processor.
