Protocol selection and interface generation for HW-SW codesign

摘要

The aim of this paper is to present a communication synthesisnapproach stated as an allocation problem. In the proposed approach,ncommunication synthesis allows to transform a system composed ofnprocesses that communicate via high-level primitives through abstractnchannels into a set of processes executed by interconnected processorsnthat communicate via signals and share communication control. Thenproposed communication synthesis approach deals with both protocolnselection and interface generation and is based on binding/allocation ofncommunication units. This approach allows a wide design spacenexploration through automatic selection of communication protocols. Wenpresent a new algorithm that performs binding/allocation ofncommunication units. This algorithm makes use of a cost function tonevaluate different allocation alternatives. We illustrate through annexample the usefulness of the algorithm for allocating automaticallyndifferent protocols within the same application system
