Design of Nios Ⅱ Floating-Point Coprocessor Based on CORDIC Algorithm
With the increasingly widespread application of transcendental functions in the field of digital signal processing,how to efficiently calculate transcendental functions has become the key to improving computing speed.This paper proposes a Nios Ⅱ floating-point coprocessor software IP core based on the CORDIC algorithm to address the current issue of many CPUs lacking hardware computing resources for transcendental functions and occupying a lot of resources for pure software computing.The 32-bit floating-point coprocessor is implemented using FPGA de-vices,which improves real-time performance and has the characteristics of fast speed and less hardware resource consumption.It can be widely used in fields involving transcendental func-tion calculation,such as digital signal processing,and has certain engineering value.
