摘要
得益于强大并行处理能力,TMS320C6678在信号处理中应用十分广泛,特别是雷达信号处理领域。信号处理中经常需要对复数求模,而传统的求模方法在TMS320C6678上效率极低,严重影响了其处理效率。本文针对TMS320C6678进行了复数求模算法的优化研究,并给出了四种复数求模算法的效率和精度的对比。
TMS320C6678 is widely used in digital signal processing algorithms due to its powerful parallel processing capability, especially in radar digital signal processing field. The complex number modulus is often needed to be calculated in digital signal processing, however very low efficiency of the traditional algorithm for complex modulus calculation on TMS320C6678 affects its processing efficiency seriously. Based on TMS320C6678, optimization of complex modulus algorithm is studied; comparison results of four algorithms in efficiency and accuracy are provided.
