New approach of fast matrix access for real-time SAR system

Based on the analyzing read-and-write features for synthetic aperture radar real-time processing and synchronous dynamic random access memory, an optimized fast matrix access algorithm is presented. The new method has been implemented on TS201 processing platform, which is used to process radar signal. Based on the analysis of experiment, it can be known that this new algorithm can achieve a constant speed and high efficiency for matrix access without altering bus data rate. The efficiency of real-time SAR system can be increased because of using the new approach of matrix access.
