摘要

提出了在并行TI tms320c40平台上实现整数小波变换的方法。设计空间探索不是由算法优化驱动的，而是由数据传输和存储估计驱动的。本文的研究重点在于详细的记忆组织探索。讨论了一些实现方法。基于所选平台的内存约束，选择了经典的行-列方法。通过有效地利用TMS320C40的dma功能，我们实现了近乎实时的实现。

Implementation of an integer wavelet transform on a parallel TI TMS320C40 platform

We present the implementation of an integer wavelet transform on a parallel TI TMS320C40-platform. The design space exploration is not driven by arithmetic optimizations, but rather by data transfer and storage estimates. The main focus of this paper lies on the detailed memory organization exploration. A number of implementation approaches is discussed. Based on the memory constraints imposed by the selected platform, the classical row-column approach was selected. By efficiently exploiting the DMA-facilities of the TMS320C40, we have realized a near real-time implementation.
