摘要
ＡＤＳＰ－２１０６Ｘ是当前性能最高的浮点ＤＳＰ处理器之一，利用它可方便地构成多处理器并行数字信号处理器，统一的地址空间允许处理器间直接存取每一片ＡＤＳＰ－２１０６Ｘ的片内ＳＲＡＭ，片内分布总线总裁逻辑允许直接把六片ＡＤＳＰ－２１０６Ｘ和一个主机组成一个多机并行系统。本文讨论了基于ＡＤＳＰ－２１０６Ｘ的数字信号处理器的设计方法并给出了它在“移位付立叶变换”算法中的应用。
ADSP 2106X is one of the most excellent perfomance DSP chips. It offers powerful features tailored to multiple processor parallel digital signal processing systems. The unified address space allows direct interprocessor accesses of each ADSP 2106X′s internal memory. Distributed bus arbitration logic is included on chip for simple, glueless connection of systems containing up to six ADSP 2106Xs and a host processor. In this paper, the design method of DSP systems based on ADSP2106X have been discussed. The application of DSP in Shifted Discrete Fourier Transform algorithm is also gived.
