提供了一种低成本的数字图像处理解决方案。研究了以DSP为核心的高性能压缩和处理系统。系统使用CCD获取原始数字图像数据，采用快速算法实现了核心的二维DCT变换，经过编码后，在一个16位定点DSP上实现了快速图像压缩。实验证明，该系统性能良好。
关 键 词 静态图像; 快速离散余弦变换; JPEG标准; DSP实现
With the development of Internet and consumer electronics, multimedia technology, including audio, video, static image and etc, has been widely used in various kinds of applications. Digital images, which were once a dream for most people, become a degage and simple procedure ascribing to the appearance of digital camera. For the reason that Digital Signal Processor (DSP) is the core of digital camera in general, the research of implementation of real time image procession on DSP is important. The goal of this thesis is to establish a high performance image processing encoding system on DSP.
