摘要
针对离散多项式变换(DPT)在实时信号处理中的广泛应用,其运算速度受到DSP器件性能限制的实际情况,研究了DPT算法,提出其具有扩维并行性,并进行了算法的并行性能分析,在基于紧耦合多处理机上实现了扩维DPT算法。实验表明,所开发的并行DPT算法运行结果与理论分析吻合,算法速度和精度均得到保证。
With respect to Discrete Polynomial Transform (DPT) widely used in real-time signal processing with limitation in operation speed of DSP, the paper makes a study on DPT parallel and its parallel performance. Based on multiprocessor platform-TMS320C80 programming structure, the paper studys the realization of DPT. Several experiments demonstrated the effectiveness of the proposed algorithm.
