ADSP21062实现的通用信号处理板

Geneal DSP Board using ADSP21062

我们采用ＡＤＳＰ２１０６２开发了一种通用数字信号处理板，它具有简洁的输入、输出接口，并且可通过ＩＳＡ总线与微机通讯。该信号处理板具有典型的输入、运算、输出三级结构，各级均可由软件控制，并可插接一个ＳＨＡＲＣＰＡＣ标准模块，可按运算量需求选择参与运算的ＡＤＳＰ芯片个数，最高处理能力达１３２０Ｍｆｌｏｐｓ／ｓ。由于具有很强的灵活性，该板能够适于许多需要高速ＤＳＰ处理的应用场合。

We developed a general DSP board using ADSP21062. It has simple and clear interface and can communicate with PC through ISA bus. The DSP board has a typical three-stage architecture, which include input calculation and output, any stage can be controlled by software. We can use SHARCPAC (a standard DSP module) and select the number ADSP chips that take part in the calculation according to the calculating requirement then we can improve the board processing speed to 1320 Mflops/second. Because the board is very flexible, it can be used and has been used in many DSP applications.
