Fast Fourier transform(FFT) accelerator and Coordinate rotation digital computer(CORDIC) algorithm play important roles in signal processing. We propose a configurable floating-point FFT accelerator based on CORDIC rotation, in which twiddle direction prediction is presented to reduce hardware cost and twiddle angles are generated in real time to save memory. To finish CORDIC rotation efficiently, a novel approach in which segmentedparallel iteration and compress iteration based on CSA are presented and redundant CORDIC is used to reduce the latency of each iteration. To prove the efficiency of our FFT accelerator, four FFT accelerators are prototyped into a FPGA chip to perform a batch-FFT. Experimental results show that our structure, which is composed of four butterfly units and finishes FFT with the size ranging from 64 to8192 points, occupies 33230(3%) REGs and 143006(30%)LUTs. The clock frequency can reach 122 MHz. The resources of double-precision FFT is only about 2.5 times of single-precision while the theoretical value is 4. What's more, only 13331 cycles are required to implement 8192-points double-precision FFT with four butterfly units in parallel.

Sweeney, Robertson and Tocher（SRT） algorithm is a common and efficient way for division and square root（div/sqrt）. We present to overlap two iterations into one cycle by predicting remainder and *** reduce latency, redundant representation is used superiorly, as well as the use of a minimum redundancy *** and square root can be integrated into one unit which causes a reduction in hardware cost. With 40 nm technology library, the area of our architecture after layout design, is 37795μm2, the power is 81.19 m W and the delay is only 656 ps. The cycles for double-precision division and square root are 17 and 16, respectively. Experiments show our architecture achieves small latency and high frequency,together with modest area and power.
