Abstract

Computation of floating-point trigonometric functions has a relevant importance in a wide variety of scientific applications, where the area cost, error and latency are important requirements to be attended. This paper presents an architecture based on CORDIC algorithm to implement single-precision floating-point trigonometric functions with small area. With mathematical transformation and high-precision fixed-point arithmetic instead of floating point operations, this paper addresses three questions for single-precision floating point trigonometric functions, including the range of angles is not enough, large area and low operating frequency. The method is implemented on the FPGA platform, the results show that this method can reduce the area effectively, and to ensure the accuracy of computation.
