    Abstract: In one form, a clock doubler includes a switched inverter, an exclusive logic circuit, and a control signal generation circuit. The switched inverter has first and second control inputs for respectively receiving first and second control signals, a signal input for receiving a clock input signal, and an output. The exclusive logic circuit has a first input for receiving the clock input signal, a second input coupled to the output of the switched inverter, and an output for providing a clock output signal. A control signal generation circuit provides the first and second control signals in response to the clock output signal. The clock doubler may be used in a clock distribution circuit for an integrated circuit that also includes a phase locked loop for providing the input clock signals, and a plurality of clock sub-domains each having one of the clock doublers.

    Abstract: The low end operating voltage of an integrated circuit is adjusted. Oscillations are counted at a ring oscillator on the integrated circuit over a designated period of clock cycles. Based on the number of oscillations, a prediction model associated with a first set of device degradation data and a second set of static random-access memory (SRAM) low end operating voltage data is used to select a low end operating voltage limit for a processor on the integrated circuit. The low end operating voltage of the processor is set based on the selected low end operating voltage limit. These steps are repeated multiple times during operation of the processor. A method of testing integrated circuits to provide the data employed to produce the prediction model is also provided.

    Abstract: A processing system includes a compute die and a stacked memory stacked with the compute die. The stacked memory includes a first memory die and a second memory die stacked on top of the first memory die. A parallel access using a single memory address is directed towards different memory banks of the first memory die and the second memory die. The single memory address of the parallel access is swizzled to access the first memory die and the second memory die at different physical locations.

    Abstract: Some embodiments of a processing device include one or more power supply monitors to provide one or more counts representative of one or more operating frequencies of one or more circuit blocks based on a voltage supplied to the circuit block(s). Some embodiments of the processing device also include a system management unit to determine an initial voltage supplied to the circuit block(s) based on a target count and to reduce the voltage supplied to the circuit block(s) from the initial voltage in response to the count(s) generated by the power supply monitor(s) exceeding the target count.
