The Unified Fast Implementation of Elementary Functions in the Embeded Coprocessor
嵌入式协处理器初等函数的快速统一实现

In this paper, the unified CORDIC algorithm is put forward by the improvement of iterative sequence and the presence of rational approximation. The unified algorithm of elementary functions is implemented with high speed. A coprocessor core using the improved algorithm is built by Verilog HDL. The core is very suitable for embedded application due to its small scale, high speed and simple control.
