Abstract

The invention discloses an area optimization method of an MPRM circuit. The method comprises the following steps: firstly, expressing the MPRM circuit by adopting a function expression; converting thefunction expression of the MPRM circuit into an MPRM expression of P polarity by using a polarity conversion method; obtaining an MPRM expression of the P polarity, associating each parameter of MPRMcircuit area optimization with each parameter of a discrete ternary particle swarm algorithm, constructing a fitness function of area optimization, and finally performing area optimization by adopting the discrete ternary particle swarm algorithm based on the fitness function. The method has the advantages of high search efficiency, strong local optimization capability and good optimization effect.

Description

technical field [0001] The invention relates to an area optimization method, in particular to an area optimization method for an MPRM circuit. Background technique [0002] A fixed-polarity RM (fixed-polarity Reed-Muller, FPRM) circuit usually has two kinds of logic function expressions. In the first logic function expression of the FPRM circuit, the variables only exist in the original variable state or only in the inverse variable state. In the second logic function expression of the FPRM circuit, the variables can exist both in the state of the original variable and in the state of the inverse variable. The difference in the states of the variables in the logic function expression of the FPRM circuit leads to differences in the size of their corresponding polar spaces. Taking the logic function of the MPRM circuit with n input variables as an example, the logic function has polarities up to 3 n , the total number of logic function expressions of the MPRM circuit in diff...
