COMMUNICATIONS SYSTEM AND METHOD WITH NON-BLOCKING SHARED INTERFACE

摘要

A communication system (100). One embodiment includes at least two functional blocks (102, 104), wherein a first functional block (102) communicates with a second functional block (104) by establishing a connection. A connection is a logical state in which data may pass between the first functional block (102) and the second functiohnal block (104). One embodiment includes a bus (112) coupled to each of the functional blocks (102, 104) and configured to carry a plurality of signals. The plurality of signals includes a thread identifier that indicates a transaction stream the data transfer is part of and a busy signal identified by the thread identifier. The busy signal is issued by the target functional block when resources will be unavailable to perform a transfer.
