    摘要: Described herein are apparatus, method, and system for reducing clock-to-output delay of a sequential logic unit in a processor. The apparatus comprises a sequential unit including: a data path, to receive an input signal, including logic gates to operate on a first power supply level, the data path to generate an output signal; and a clock path including logic gates to operate on a second power supply level, the logic gates of the clock path to sample the input signal using a sampling signal to generate the output signal, wherein the second power supply level is higher than the first power supply level. The apparatus improves (i.e. reduces) setup time of the sequential unit and allows the processor to operate at minimum operating voltage (Vmin) without degrading performance of the sequential unit.

    摘要: Disclosed herein are semiconductor device arrays, such as, Field Programmable Gate Arrays (FPGAs) and Complex Programmable Logic Arrays (CPLAs) that use high-density Spin Transfer Torque (STT)-based memory elements. STT-based memory elements can either be stand-alone FPGAs/CPLAs, or can be embedded in microprocessors and/or digital signal processing (DSP) system-on-chip (SoC) to provide design flexibility for implementing low power, scalable, secure and reconfigurable hardware architecture. Because the configuration is stored on the FPGA/CPLA die itself, the need for loading the configuration from external storage every time is eliminated when the device is powered on. In addition to instant startup, eliminating configuration I/O traffic results in power savings and possible pin count reduction. Security is greatly improved by eliminating the need to store configuration data in an external memory.

    摘要: A system may include detection of a direction of transistor body current flow, and control of a regulator transistor to regulate a transistor body voltage based on the detected direction. In some aspects, a first regulator transistor is controlled if the direction of current flow is into a transistor body and a second regulator transistor is controlled if the direction of current flow is out of the transistor body.

    摘要: A bias generator unit is provided that includes a central bias generator to provide a bias voltage, a local bias generator to receive the bias voltage and a reference voltage and to provide a forward body bias signal or a reverse body bias signal. The bias generator may include a charge pump to output (or provide) a reference voltage to a reference generator, which in turn provides reference signals to the central bias generator. As a result, the local bias generator may control the body bias signal provided by the local bias generator.
