Parallel DSP for real-time control

The nature of several algorithms from the active vibration control domain is discussed and the issues of algorithm parallelisation and mapping are introduced. The algorithms have been implemented on the network of C40s and the real-time performance evaluated. In all the cases, a single C40 has shown enough processing power for the real-time implementation of the algorithms. Multiprocessor implementation did not offer very impressive performances as compared to ideal speedup, due to communication overhead, run-time memory management and some other unpredictable features of the architecture. However, the obtained real time performances of the uni-processor and the multi-processor architectures are quite reasonable
