    摘要： A method of power management of a system of connected components includes initializing a token allocation map across the connected components, wherein each component is assigned a power budget as determined by a number of allocated tokens in the token allocation map, monitoring utilization sensor inputs and command state vector inputs, determining, at first periodic time intervals, a current performance level, a current power consumption level and an assigned power budget for the system based on the utilization sensor inputs and the command state vector inputs, and determining, at second periodic time intervals, a token re-allocation map based on the current performance level, the current power consumption level and the assigned power budget for the system, according to a re-assigned power budget of at least one of the connected components, while enforcing a power consumption limit based on a total number of allocated tokens in the system.

    摘要： An integrated circuit including a pipeline and a method of operating the pipeline. Each stage of the pipeline is triggered by one or more triggering events and are individually, and selectively, stalled by a stall signal. For each stage a stall signal, delayed with respect to the stall signal of a downstream stage, is generated and used to select whether the pipeline stage in question is triggered. A data valid signal propagating with valid data adds further selection, such that only stages with valid data are stalled.

    摘要： A synchronous pipeline segment and an integrated circuit (IC) including the segment. The segment includes an input stage, an output stage and at least one intermediate stage. A place holder latch associated with each stage indicates whether valid stage data is in the stage. A local clock buffer provides a local clock gating a corresponding stage. The input and output stages are normally opaque and intermediate stages are normally transparent. Data items pass locally asynchronously between the input and output stages and are separated by opaque gated intermediate stages.

    摘要： A system for topology selection to minimize leakage power during synthesis, wherein the system is configured to receive a circuit model that has one or more circuit gates. The system is further configured to receive a library having one or more logic gates, wherein each logic gate has a topology and the leakage sensitivities for each of the topologies is calculated. The system is then configured to synthesize a new circuit model by selecting one or more of the topologies based on its leakage sensitivities, wherein the new circuit model has reduced current leakage.
