A codesign experiment in acoustic echo cancellation: GMDF/spl alpha/

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 (GMDF/spl alpha/ 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.
