主　　题：Fast Fourier transform (FFT) Multi-core Parallel computing SIMD 

摘      要：The fast Fourier transform (FFT) is a fundamental kernel of many computation-intensive scientific *** paper deals with an implementation of the FFT on the accelerator system,a heterogeneous multi-core architecture to accelerate computation-intensive parallel computing in scientific and engineering *** Engineering and Scientific Computation Accelerator (ESCA) consists of a control unit and a single instruction multiple data (SIMD) processing element (PE) array,in which PEs communicate with each other via a hierarchical two-level network-on-chip (NoC) with high bandwidth and low *** exploit the architecture features of ESCA to implement a parallel FFT algorithm *** results show that both the proposed parallel FFT algorithm and the ESCA architecture are *** 16-bit fixed-point parallel FFT performance of ESCA is compared with a published work to prove the superiority of the mapping algorithm and the hardware *** floating-point parallel FFT performances of ESCA are evaluated and compared with those of the IBM Cell processor and GPU to demonstrate the computing power of the ESCA system for high performance applications.
