Introduced the (SPECtral Analysis) SAR imaging algorithm based on the two TMS320C6678 project. In this paper, the principle 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 implementation results. 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.
