Parallel Processing - the picoChip way!

摘要

This paper describes a new approach to parallel processing within the well targetted application domain of wireless communications systems, using the picoArray. The picoArray is a tiled-processor architecture, containing 430 heterogeneous processors, connected through a novel, compile-time scheduled interconnect, We show how the features of the picoArray allow deterministic processing to be achieved, and how the tool chain allows programming to be performed effectively in a combination of high level assembly language and C. By handling a wide variety of types of processing within the picoArray a single design flow can be used to produce complex communications systems. The effectiveness of this approach is demonstrated through the use of the picoArray to build a working 3G base-station.
