摘要： Reducing power consumption in latches and similar electronic devices. In one aspect, an apparatus for configuring power consumption of sequential logic includes a sequential logic device including a first latch, a second latch, and first and second enable inputs. The first enable input enables and disables the first and second latches, and the second enable input enables and disables the second latch and does not affect the first latch. The first enable input has an earlier required signal arrival time than the second enable input to be effective for a particular clock cycle. A circuit configures the sequential logic device at operating time to consume less power during a lower frequency of operation of the sequential logic device, and to consume more power during a higher frequency of operation.

摘要： The present invention provides a method and system for fixed length bursts of data on a bus within a data processing system. The method and system in accordance with the present invention provides a burst transfer protocol which includes the providing of length information of a fixed length burst of data on a signal from at least one master device to at least one slave device when the at least one master device requests the fixed length burst of data. It also includes the asserting of a burst termination signal by the at least one slave device one cycle prior to a last cycle in the fixed length burst, and the asserting of a burst complete signal during the last cycle in the fixed length burst for a write burst, or one cycle prior to the last cycle in the fixed length burst for a read burst, based on the value of the signal. This burst transfer protocol enables burst transfers of a maximum length to be performed across a local bus between a master and a slave without dead cycle penalties after the transfer. This improves the efficiency and performance of data throughput across the local bus without the need to increase the frequency. The present invention requires no new signals and is optional so a master and slave who use the protocol of the present invention is compatible with masters and slaves who do not.
