Abstract
A combinational logic type inversion circuit for calculating the inverse of an arbitrary element .alpha..sup.i in a finite field, includes a power and multiplication circuit for calculating a primitive element .alpha..sup.i raised to the (2.sup.1)-th power through a primitive element .alpha..sup.i raised to the (2.sup.m-1)-th power and multiplying all of the primitive elements .alpha..sup.i raised to the (2.sup.1)-th power through .alpha..sup.i raised to the (2.sup.m-1)-th power together to generate an output M.sub.OUT, and a divider circuit for dividing the output M.sub.OUT of the power and multiplication circuit by the primitive element .alpha. raised to the (2.sup.m -1)-th power.
