| 摘 要： | 合成孔径雷达(SAR)是全天候全天时的主动微波成像雷达,因此在军事和民用方面得到了广泛的应用。合成孔径雷达成像的显著特点是数据吞吐量大,实时性强,然而单片的高性能DSP无法满足SAR成像的需求,故采用多片DSP技术。在多片DSP并行处理技术中,它们之间如何进行通信是一个关键技术。本文以ADSP2106x为例,研究了DSP间的通信以及DSP与PC机间的通信。串行通信、DMA通信和VC++的MSComm控件通信都是很好的通信方式,但DMA更适合大量的数据通信。

| Abstract: | Synthetic Aperture Radar (SAR) is an active microwave imaging radar that can image at all-weather and all-time, so it has been widely applied in military and civilian fields. The remarkable characteristics of synthetic aperture radar are lots of data throughput and real-time strength. However, single DSP of high performance can not satisfy the requirement of SAR imaging, so multi DSP technology is used in it. How to communicate is a key technology in multi-DSP parallel processing Technology. With ADSP2106x as an example, the communications were researched between DSP and PC. Serial communication, DMA communication and MSComm control communication of VC++ are all good communication methods, but DMA method is more fit for a mass of data communication. |
