A method of mapping combinational logic into PCA plastic part

摘要

This paper proposes a method of mapping combinational logic into PCA plastic parts. The PCA is a general-purpose computer architecture based on the dynamic reconfiguration of functions. It consists of a two-dimensional array of PCA cells, each of which consists of a Nastic part and a built-in part. The plastic part is a programmable logic, while the built-in part supports the dynamic reconfiguration. We have already developed a method of mapping finite stats machine into PCA plastic part as a part of logic synthesis system for PCA. Here, we create a method to minimize the combinational circuit size. Some benchmark suits are mapped to estimate the efficiency. Experimental results show that the method can effectively reduce circuit size.
