Implementation of SPECAN Imaging Processing Algorithm Based on TMS320C6678DSP Multicore Programming

介绍了SPECAN(SPECtral analysis)SAR成像算法基于2片TMS320C6678的工程实现。文中对SPECAN SAR成像算法原理做了简单介绍,对算法工程化实现进行重点描述,着重对实现过程中DSP多核间同步、2片DSP间的同步、多核多通道EDMA传输以及大数据量存取及解决措施进行了介绍,并给出了工程实现结果。与其他几种成像算法工程化比较,通过结论可知对于成像精度要求不高,但要求快速实时处理时,SPECAN算法为最理想的工程化实现成像算法。

Introduced the （SPECtral Analysis） SAR imaging algorithm based on the two TMS320C6678 project. In this paper, the princi- ple of （Analysis SAR） SPECtral imaging algorithm is briefly introduced, focus on the description of the algorithm of implementation of the project, focusing on the implementation process of DSP multi-core synchronization, synchronization between 2 pieces of DSP, multi core and multi channel EDMA transmission and a large amount of data access and the solving measures are introduced, and gives the implemen- tation resuhs. Compared with other imaging algorithms, it can be concluded that the SPECAN algorithm is the most ideal project to realize the imaging algorithm in the fast and real time processing.
