高级综合中寄存器合并问题的研究

A Study on Register Merging Problem for High-level Synthesis

高级综合技术的研究在当前倍受关注。在进行资源分配时，为了减少互连线的数目，提高设计质量，应对数据路径综合中所需的寄存器进行合并。通过对寄存器合并问题进行研究分析，给出了一种高级综合中的寄存器合并算法。经实验证明，该算法具有速度快、效率高的特点，应用在高级综合系统中时，可提高综合设计的质量。

High-level synthesis is an active area of research Presently.In the process of resource allocation,the registers required in datapath should be merged in order to reduce the interconnechon wires.Based on the study of the register merging,a register merging algorithm ispresented in this paper.This algorithm is very efficient and can improve the quality of the design in high-level synthesis.
