摘要
数字信号处理器(DSP)在高速运算上有着不可比拟的优势,但数字信号处理的数据量庞大,需要一种非常方便、快捷的接口实现与计算机的数据传输。在CT图像重建系统设计中,提出一种基于DSP和USB的高速数据传输方案,该方案采用CYPRESS的CY7C68001作为USB收发控制芯片,并使用TI的高性能DSP芯片TMS320C6416作为微处理器控制芯片,利用两者的速度优势,通过C语言编写通信程序,实现了DSP与PC机之间的高速数据传输,从而使得大量图像数据能够快速、实时的存储、处理。
DSP′s high speed operation function makes it have the unique advantage on the processing of the digital signals.Usually the data of the digital signals are so huge that convenient interface of high speed is needed to connect with PC.In the design of CT image reconstruction system,a precept of high speed data transmission system based on DSP and USB is proposed.Selecting CYPRESS′CY7C68001 for USB receiver/transfer control chip and TI′TMS320C6416 for micoprocessor control chip and writing the communication program in C language,it can achieve high speed data transfer between DSP and PC by their speed. Therefore,it can realize high speed,real- time storage and process for mass image data.
