Abstract
The circuit consists of two parallel branches which perform multiplication and accumulation operations for the even and odd lines of the transform coefficient matrix. Each branch includes: an input circuit (SEM1, SOT1) whereby the contributions of the opposing index columns of the matrix may be added; a multiplication circuit (ERM, ORM) which performs multiplication operations for each matrix column by an addition and shifting operation for each matrix coefficient; and an accumulation circuit for the intermediate products of each matrix column.
