Abstract:
A processor 4 is provided with reset circuitry 48 which generates a reset signal to reset a plurality of state parameters. Partial reset circuitry 50 is additionally provided to reset a proper subset of this plurality of state parameters. The reset circuitry triggers a redirection of program flow. The partial reset circuitry permits a continuation of program flow. The partial reset circuitry may be used to place processors into a known state with a low latency before switching from a split mode of operation into a locked mode of operation.
