摘要
Abstract
With the development of SAR imaging towards high resolution and wide swath,ωK algorithm is applied more and more widely.Stolt interpolation is the core of ωK algorithm,which requires the large amount of computations and high calculation precision.The traditional DSP is difficult to meet the demand. Multi-core and multi-DSP parallel processing is an important development trend.This paper introduces a kind of 4 pieces of TMS320C6678 general signal processing platform,which has built-in 8 cores,strong fixed-point and floating-point processing ability.As a case study of stolt interpolation,the multi-core and multi-DSP parallel implementation is discussed.Using the DMA CHAIN technology to implement the data access reduces the data access time effectively and improves the real-time performance of the system.关键词
