Abstract

See full text

A computer implemented method, bus switching system, and computer usable program code are provided for saving bus switching power and reducing noise. A request for data is received from a requester by a first cache. A determination is made as to whether the data is stored on the first cache. Responsive to determining that the data is stored on the first cache, a bus in a plurality of buses is identified on which to return the data forming an identified bus. The data is sent to the requester on the identified bus. A logical state is initiated on the remaining plurality of buses stemming from the first cache in order to save bus switching power and reducing noise.
