Abstract
A method for non-periodic limits mitigation is described. The method includes monitoring operation of each processor thread during thread pipeline execution. The method also includes detecting a limits management condition based on each of the processor threads during the thread pipeline execution. The method further includes controlling application of a limits mitigation operation to perform non-periodic application of the limits mitigation operation to the thread pipeline execution.
Claims17
A method for non-periodic limits mitigation, the method comprising:
- monitoring operation of each processor thread during thread pipeline execution;
- detecting a limits management condition based on each of the processor threads during the thread pipeline execution;
- and
- controlling application of a limits mitigation operation to perform non-periodic application of the limits mitigation operation to the thread pipeline execution,
- wherein controlling application of the limits mitigation operation comprises accessing configuration register values to configure a dither control circuit, and
- wherein the dither control circuit comprises a modulation block and a random number generator block selected according to the configuration register values.
A non-periodic limits mitigation system, comprising:
- a multi-threaded processor comprising a dither control circuit to control application of a limits mitigation operation to perform non-periodic application of the limits mitigation operation to a thread pipeline execution when a limits management condition is detected based on the thread pipeline execution of the multi-threaded processor,
- wherein the dither control circuit comprises a modulation block and a random number generator block selected according to configuration register values.
