用DSP Builder设计基于PLD的数字信号处理器

Designing a Digital Signal Processor with DSP Builder based on PLD

不断发展的 DSP技术迅速地拓宽扩展到了各应用领域 ,但传统的 DSP处理器由于以顺序方式工作而数据处理速度较低 ,且在功能重构及应用目标的修改方面缺乏灵活性。本文介绍一种崭新的基于 Matlab与 Quartus II的 DSP处理器的设计软件 DSP Builder,详细介绍了其设计流程与优点 ,并以 DDS直接数字合成器的实现为例说明用该软件来设计 DSP处理器的方法以及与 Matlab、Quartus

The developing DSP technique spreads to more and more fields rapidly, but traditional DSP processor either runs slowly because of it executing in sequence, or has shortcoming in function reconstuction and application-modifying. This article introduces a new software of building a Digital Signal Processor which is based on Matlab and QuartusII named DSP Builder. And it also details the flow of design and its advantages. To explain its usage for instance we also introduce the implementing of a DDS and the relationship between Matlab & QuartusⅡ.
