摘要：

In This paper, we present a multi-core mapping implementation of 3780-point FFT as an application in DTMB system. By using SIMD commands and optimizing of specific modules, complication is decreased. Through the proper task arrangement we avoid the synchronizations and conflicts. A multi-core mapping based on multi-core processor can reach a high throughput up to 32.64 M Sample/s while the platform is running in 750MHz. The throughput of output is even higher than the VLSI result. The energy efficiency is given which is close to the VLSI result
