Coordinate Rotation Digital Computer (CORDIC) was an efficient algorithm to compute elementary arithmetic such as multiplication, division, and root extractions. However, conventional CORDIC algorithm requires high latency to obtain the results. This paper proposes a low latency parallel pipeline CORDIC (PP-CORDIC) to calculate trigonometric functions. The results show that PP-CORDIC can operate at 83.64 MHz frequency with the latency was 10, 15, and 17 clock cycles in the best, average, and worst case, respectively. The hardware architecture occupies 7,035 LUTs, and 3,409 registers on Stratix IV FPGA. � 2016 IEEE.
