The implementation is carried out on a fixed-point digital signal processor (DSP). The fixed-point BFP FFT results are contrasted with the results of a floating-point FFT of the same size implemented with MATLAB. For applications where the FFT is a core component of the overall algorithm, ...
the exact upper bound and lower bound of mean square error are obtained for the two FFT algorithms of fixed point and block floating point. 得到了准确的定点和块浮点两种FFT算法的均方误差上下限。 www.juyy.net 2. Present a improved block floating point algorithm which solves the overflow in lon...
FFT (Fast Fourier Transform, [2]) block is of key importance while designing the ASIC for a DSL modem. The reason is that it takes a lot of area and power on the chip. The hardware implementation of the algorithm can be done in either fixed or floating point. For the floating point ...
I am working on an embedded project with Altera DE2-115, and I would like to ask if the Nios II/e processor can process the output from the FFT IP block in floating-point format? Please note that the process for the exported FFT coeff will be on software with C. Thank you...
Burrus has presented a block processing approach for recursive digital filters based on the FFT [3]. However, this approach is efficient only for filter orders of 10 or more and for block lengths of 100 or more. Another approach is the block processing or state-decimation technique [27, 29...
PURPOSE: A method and a device for scaling the CBFP(Convergent Block Floating-Point) for a pipelined FFT(Fast Fourier Transform) processor are provided to reduce a chip area and the power consumption, to minimize the increase of the output latency by the CBFP scaling, and to increase the ...
