Arithmetic program conversion apparatus, arithmetic program conversion method, and program

摘要

An arithmetic-program conversion apparatus includes: a program storage section storing an arithmetic program describing a circuit by a logical expression including a plurality of input and output variables, and operators; if the expression has three input variables or more, an intermediate-variable generation section generating an intermediate variable for converting the expression into a plurality of binomials including input and output variables; if the intermediate variable is generated, an expression conversion section converting the logical expression into a plurality of binomials including a binomial for obtaining the intermediate variable and a binomial obtaining the output variable from the intermediate variable; if a plurality of binomials are generated, an expression update section updating the stored original expression; a bit-width determination section determining bit widths of the output, input, and intermediate variables of the expression; and a bit-width storage section storing the bit widths of the output, input, and intermediate variables.
