Abstract
Hardware/software codesign approaches consist generally in HW/SW partitioning and scheduling, constrained code generation, hardware and interface synthesis. This paper presents the codesign of an industrial experiment in acoustic echo cancellation (GMDFα algorithm) and emphasizes the partitioning and communication synthesis steps. This experiment points out interesting problems such as data and programs distribution between system memories and modeling communications in the partitioning process
