    摘要: A system and method can mitigate voltage fluctuations. According to one embodiment, a delay system provides a delayed version of a first reference signal as a function of a supply voltage. A comparator provides a control signal for controlling a protection device based on the delayed version of the first reference signal and a second reference signal. The amount of delay provided by the delay system defines a threshold based on which the comparator provides the control signal.

    摘要: A thermal sensing system may comprise a plurality of remote sensors distributed across an integrated circuit (IC). Each of the plurality of remote sensors provides an analog signal that varies as a function of temperature of a respective region of the IC where each respective remote sensor is located. A central system, forming part of the IC, samples the analog signals from the plurality of remote sensors and converts the sampled analog signals to corresponding digital values.

    摘要: A computer processor integrated circuit has multiple functional units, where each unit is coupled to a register file for reading and writing operands. An instruction fetch unit receives instructions from a memory system and dispatches commands to the functional units. The processor has a resource status flags register wherein particular units may be marked enabled or disabled. The instruction fetch and decode unit checks the resource status flags register prior to dispatching commands and dispatches commands only to those functional units marked enabled. The instruction fetch and decode unit is capable of dispatching commands to available units, and of stalling and dispatching remaining commands in a following cycle if insufficient resources are available to simultaneously dispatch all commands necessary to execute an instruction or group of instructions.
