VARIABLE LATENCY INSTRUCTIONS

This abstract first appeared for US patent application 20240411559 titled 'VARIABLE LATENCY INSTRUCTIONS

Original Abstract Submitted

techniques related to executing instructions by a processor comprising receiving a first instruction for execution, determining a first latency value based on an expected amount of time needed for the first instruction to be executed, storing the first latency value in a writeback queue, beginning execution of the first instruction on the instruction execution pipeline, adjusting the latency value based on an amount of time passed since beginning execution of the first instruction, outputting a first result of the first instruction based on the latency value, receiving a second instruction, determining that the second instruction is a variable latency instruction, storing a ready value indicating that a second result of the second instruction is not ready in the writeback queue, beginning execution of the second instruction on the instruction execution pipeline, updating the ready value to indicate that the second result is ready, and outputting the second result.
