近年来，随着DSP的快速发展，被广泛的应用于图像处理及目标定位[11][13][21]上，极大地提高图像处理的实时性。DSP主要用来实现扩展算法和数字信号处理的功能，其最典型的用途是实现数字图像处理算法。DSP芯片内采用大容量的SRAM作为系统的高速缓存，高达64位的数据总线带宽。在片外采用了目前流行的SDRAM、DDR2等高速大容量存储器的无缝连接，同时还支持SRAM、FIFO等各种类型的存储器，大大提高了图像的存储容量及速度。-In recent years, with the rapid development of DSP, has been widely used in image processing and target location [11] [13] [21], and greatly improve the image processing in real time. Mainly used to implement DSP algorithms and digital signal processing expansion of the function, the most typical use digital image processing algorithms. DSP chip with large-capacity SRAM cache as a system, up to 64-bit data bus bandwidth. Chip used in the popular SDRAM, DDR2 memory and other high-speed large-capacity seamless connection, and also supports SRAM, FIFO, and other types of memory, greatly improving the image storage capacity and speed.
