“…Speech coding algorithms are usually computationally intensive and need a significant amount of signal processing power. Conventionally, either specialpurpose DSP processors with codec-customized architectures have been designed to perform the speech signal processing tasks [22] or general-purpose DSP processors with highly optimized codec software [23]- [26] have been suggested. This work chooses the second solution by experiencing the effects of computational power growth through the multiprocessor DSP platform.…”

In this paper, we propose a multiprocessor DSP simulation toolkit suitable for performance evaluation of dataparallel applications like voice processing. The proposed toolkit uses the benefits of multi-level parallelism and clustering. Different DSP clusters are considered for the multiprocessor DSP simulation engine in which the DSP processors are grouped to cooperate. Satisfying the communication requirements, two global and local communication engines (GCE and LCE) implement the real behavior of intra-and inter-cluster communications. Using efficient abstraction levels for interconnections reduces the simulation time significantly. Abstract communication modeling, cycle-accurate behavior, and multi-level controlling are the most important features of the proposed simulation platform. Performance of the simulator is verified by standard single-and multi-channel voice processing applications such as ITU-T G.729a speech codec.

“…Such calculation is usually as follows: Calculate the value of a number of results, each of whose result value is composed by numerous cumulative sums, select a minimum value from these results for the next calculation [5]. The optimization can be used on such calculations.…”
