Abstract
Floating-point trigonometric computing is a fundamental operation in navigation systems, 3D image processing, radar signal preprocessing and so on. This paper presents a floating point trigonometric computing circuit using a CORDIC algorithm and a full custom layout method, and the output data are compatible with the IEEE-754 signal precision floating-point standard. It describes the CORDIC algorithm principle and chooses a pipeline structure based on the principle of priority on performance. A static circuit structure and a full custom layout are given in the SIMC 0.13μm 1P8M CMOS process. The silicon area of data path is 605 284/W and the critical path delay is 3.013ns in the SS (Slow-Slow) corners.关键词
