The acoustic echo cancellation with large adaptive filters isa computationally intensive problem and needs real time costeffective solution. To deal with these challenges, designers haveincreasingly turned to mixed Hardware/Software (HW/SW) implementationof echo canceller algorithms. This paper presents a co-designmethodology and environment for both hardware and software modules.We describe how High Level Synthesis (HLS) tools like GAUT and SYNDEXcan be efficiently used for rapid prototyping of heterogeneousarchitecture based on DSP TMS320C40 and ASIC. The HW/SW interfacesynthesis task is especially discussed since it constitutes a keyissue of the whole design. As an illustration, we present a mixedimplementation of the GMDF alpha algorithm, an adaptive filter wellsuited to acoustic echo cancellation, on both ASIC and TMS320C40DSP.
