摘要:
针对现有寄存器传输级（register transfer level，RTL）综合中资源共享仅针对算术逻辑单元（arithmetic logic unit，ALU）的问题，提出扩展型资源共享的方法．该方法对所有逻辑门进行共享，既可优化ALU，又可优化普通逻辑单元，突破了资源共享基于多路选择器(multiplexer，MUX)的限制，实现算术优化及逻辑优化．实验结果与开源工具ABC比较，LUT数减少了19.2%，表明该方法不仅可减少算术逻辑单元的数目，也可有效减少普通逻辑资源的数目，最终实现面积优化．
Abstract:
A new expanded resource sharing method was proposed to solve the issue that resource sharing is only for arithmetic logic unit (ALU) in RTL synthesis. All kinds of logic cells can be shared to optimize both ALUs and common logic cells. The restrictions of resource sharing based on multiplexer were resolved and the arithmetic and logic optimization were implemented. The results have demonstrated that the number of LUTs was reduced by 19.2% in comparison with open-source ABC. The number of common logic resources was also reduced significantly, which means the purpose of area optimization is achieved.
