متن کاملReal-Time and High-Accuracy Arctangent Computation Using CORDIC and Fast Magnitude Estimation
This paper presents an improved VLSI (Very Large Scale of Integration) architecture for real-time and high-accuracy computation of trigonometric functions with fixed-point arithmetic, particularly arctangent using CORDIC (Coordinate Rotation Digital Computer) and fast magnitude estimation. The standard CORDIC implementation suffers of a loss of accuracy when the magnitude of the input vector be...
متن کاملA high-throughput fixed-point complex divider for FPGAs
This paper presents a high-throughput fixed-point complex divider which uses four pipelined CORDIC units to transform and divide complex numbers in Polar coordinates. By persevering the macro-angle for CORDIC rotations in redundant form and developing an optimized pipelining structure, the FPGA based implementation achieves a 9× advantage on throughput over the best design reported. In addition...
