The fast Fourier transform (FFT)is a computationally intensive digital signal processing(DSP)function widely used in applications such as imaging ,software-defined radio, wireless communication, instrumentation and machine inspection. Historically, this has been a relatively difficult function to implement optimally in hardware leading many software designers to use digital signal processors in soft...
A configurable floating-point coprocessor by a FPGA is designed to enhance the computational capability of the digital platform based on the fixed-point DSP, with which the platform will be competent to implement intensively computational tasks. Detailed design procedures of the coprocessor are presented. A new division algorithm is proposed by combining the lookup-table algorithm and multiplicative...
