Bin Yu, Guang You Yang, Hai Huang · Applied Mechanics and Materials · 2013
CORDIC Algorithm is widely applicable to the hardware implementation of DSP, and it attaches a great importance in many hardware implementations of DSP for a lot of arithmetic operations are simplified to simple addition operations and shifting operations. The FPGA implement of sine and cosine functions are achieved through CORDIC Algorithm in the paper, and the input and output data of the entire structure complies with IEEE754 standards. The basic theory of CORDIC Algorithm is introduced first in the paper, then the hardware iterative formula and the flow chart get out of basic formulas are given, and the structure of the design is introduced in detail, at last synthesis and simulation results are given.
