The CORDIC algorithm can be implemented efficiently for trigonometric computing which is important in image processing, navigation. And a full custom implementation has better performance in low silicon area and high throughput. This paper presents a 32 bits full custom layout design for CORDIC architecture by using pipelining techniques to increase the throughput of the processor. As a result, the area of CORDIC data-path is 6.0m 2 in the SIMC 0.13m 1P8M CMOS process. The critical path delay
