    摘要: An apparatus, a method and a computer program are provided to reduce leakage current in a processor. Traditionally, extra logic is employed to reduce leakage currents. However, reducing leakage current without sacrificing fine grain operations and speed can be difficult. Achieving such a goal can be accomplished by incorporating a multiplexer (mux) into the scan-in path of scan registers so that units or sub-units of the processor can be powered down individually. Additionally, the muxes are not incorporated into time paths, so speed can be preserved.

    摘要: An apparatus, a method and a computer program product are provided for conserving energy during functional mode of a processor by disabling the scan chain. By inserting logic gating into the scan chain it is possible to disable the scan chain during the processor's functional mode. During functional mode the scan out port of the latch bit in a scan chain toggles, which leads to unnecessary energy consumption. By gating scan control signals and the scan out port of a latch bit, the scan chain segment between latch bits can be disconnected. Therefore, the scan control signals can disable the scan chain during functional mode.

    摘要: Systems and methods for decreasing the sensitivity of a sense amplifier to variations in the threshold voltages of the data line pull-down transistors by pre-charging the intermediate nodes of the sense amplifier to the voltages on the opposing bit lines when the sense amplifier is not enabled. In one embodiment, the intermediate nodes are coupled to the input bit lines through transistors that are switched on when the sense amplifier is not enabled and switched off when the sense amplifier is enabled. In one embodiment, the intermediate nodes are pre-charged to a predetermined voltage before being pre-charged to the voltages on the bit lines. In one embodiment, the bodies of the data line pull-down transistors may also be body-tied to the opposing intermediate nodes to increase current flow through these transistors, particularly on the side of the sense amplifier that will be pulled low when the sense amplifier is enabled.

    摘要: A method, an apparatus, and a computer program are provided to reduce the number of required latches in a deep pipeline wordline (WL) decoder. Traditionally, a signal local clock buffer (LCB) has been responsible for providing a driving signal to a WL driver. However, with this configuration, a large number of latches are utilized. To reduce this latch usage, a number of LCBs are employed, such that one latch can enable an increased number of WLs. Hence, the overall area occupied by latches is reduced and power consumption is reduced.

    摘要: A method, an apparatus, and a computer program are provided for predicting power consumption for chip. The model for predicting power consumptions is modified so at to provide a high degree of accuracy with a minimal amount of computing time. Traditionally, when modeling a chip, a vast amount of time and computer resources were required to predict power consumption. Techniques required less time and less computer power, but the accuracy also decreased. However, by breaking down a chip into macros and developing energy rules for each macro, simple techniques can be employed to accurately predict power consumption under real world conditions with a minimal amount of time and computing power.
