文章结合ALU设计,提出了基于等价变换的资源共享设计方法。在分析了ALU功能的基础上,给出了一个资源共享型ALU设计实例。与基于指令功能设计方法相比,资源共享设计方法在节省资源方面有独到的优势。该设计方法不仅适用于基于HDL描述的现代设计方法,而且也适用于传统的原理图设计方法。
Combined with ALU design, this paper presents a resource sharing design method based on equivalent transformation. Based on the analysis of the function of ALU, a resource sharing ALU design example is given. Compared with instruction-based design methods, resource-sharing design methods have unique advantages in resource conservation. The design method not only applies to the modern design method based on HDL description, but also to the traditional schematic design method.
