| Abstract: | In many embedded signal processing fields, the PowerPC with AltiVec technology has become the chief signal processing device replaced the traditional DSP. In order to assess the vector computing performance and signal processing capabilities of the AltiVec processing unit, select MPC8641D processor as hardware test platform, use VSI / Pro Core vector library and ixlibsav vector library to program. The test result is applied the complex multiplication and FFT typically algorithms computing time. Through the analysis of test results, the PowerPC with AltiVec technology has powerful vector computing performance, can meet the demand for high-performance processors in the embedded digital signal processing technology. |
