基于DSP Builder的非传统定点数加法器的设计

Design of nontraditional fixed-point adder based on DSP builder

本文提出了利用DSP Builder来设计与实现非传统定点数加法器的新方法。DSP Builder是Altera公司推出的一个基于FPGA的系统级的数字信号处理开发工具,非传统定点数的加法器广泛应用于特殊用途的高速运算器中。本文采用优化技术,用DSP Builder设计与实现了基于SD编码的无进位延时的快速加法电路,通过计算机仿真,取得了满意的结果。

The article presents a novel method to design and implement a nontraditional fixed - point adder based on DSP Builder. DSP Builder is a digit signal process tool in FPGA, which is provided by ALTERA company. The nontraditional fixed - point adder is wildly used in high - speed calculator. Through code optimization, no - carry delay adder based on signed digit number is presented . By computer simulation, the result of the experiment is satisfying.
