METHOD AND APPARATUS FOR DYNAMIC POWER SAVING WITH FLEXIBLE GATING IN A CROSS-BAR ARCHITECTURE

摘要

Various aspects of dynamic power reduction in a bus communication architecture are described herein as embodied in an XBAR architecture that provides flexible gating of multiple paths and repeater circuitry to allow any of a number of selected clients to communicate with any of the other interconnected clients while reducing dynamic power consumption by disabling unused repeater circuitry in the bus communication architecture.

主权项

1. A bus system, comprising:
a plurality of clients coupled by at least one communication path, wherein a first client is configured to be coupled to a subset of clients in the plurality of clients by a first communication path; at least one switched repeater located at a position along a length of the first communication path and configured to divide the first communication path into multiple portions; and control logic configured to disable the at least one switched repeater associated with any unused portion of the multiple portions of the first communication path.
