Multipass communication systems for tiled processor architectures

Multipass communication systems utilize multiple sets of parallel baseband receiver functions to balance communication data rates and available computation capabilities. This is achieved by spatially pipelining baseband functions across parallel resources to perform multiple processing passes on the same set of received values, thus allowing the system to simultaneously convey multiple sequences of data using a single wireless link. The use of multiple passes mitigates the effects of data rate on receiver processing bottlenecks, making the use of general-purpose processing elements for high data rate communication functions viable. The flexibility of general-purpose processing, in turn, allows the receiver composition to trade-off resource usage and required processing rate. For instance, a communication system could be distributed across 2 passes using 2x the overall area, but reducing the data rate for each pass and the resultant overall required processing rate, and hence clock speed, by 1/2. Lowering the clock speed can also be leveraged to reduce power through voltage scaling and/or the use of higher Vt devices. The characteristics of general-purpose parallel processors for communications processing are explored, as well as the applicability of specific parallel designs to communications processing.
