For the portability and real-time requirements of embedded signal processing software in avia-tion and communication fields,this paper proposes an algorithm accelerated optimization method for vector signal image processing library(VSIPL)middleware based on NEON under the ARM platform.The VSI-PL middleware can solve the problem of reusability of signal processing software in different platforms,by analyzing the data characteristics of VSIPL,NEON technology is applied in the acceleration design of VSI-PL to realize parallel data processing to improve the computing efficiency.Finally,performance compari-son tests are conducted on typical vector algorithms in VSIPL before and after optimization,and the im-pact of different factors on the acceleration effect is analyzed.The test results verify the feasibility of the acceleration method.Therefore,the proposed VSIPL accelerated design method based on NEON can effec-tively improve the performance of signal processing software,which has certain guiding significance and engineering application value.
