Improving "performance vs silicon size" tradeoffs using coprocessors: A case study: G.721 on OAK and Pine DSP Cores

Abstract : The increase in performance and internal memory of current DSP cores allows most applications to have software only implementations. However, recent applications in telecommunications (e.g. MPEG-4) require more and more computational power. A solution to this problem is to implement a subset of the algorithm in hardware. In this paper we present a software only and a mixed hardware/software solution for the G.721 [1] Adaptative Differential Pulse Code Modulation (AD-PCM) on VLSI Technology VVF3000 and VVF3500 DSP cores which stand for DSP Group PineDSPCore and OakDSPCore™ [2]. We will show the benefits of a coprocessor based solution and describe our methodology to extract hardware blocks from a software implementation.
