POLYNOMINAL EXPRESSION MULTIPLICATION CIRCUIT OF DIGITAL SYSTEM

摘要

The invention provides the polynomial multiplier to simplify the integrated circuit size and the hardware configuration. The system comprises; search block (10,11) outputting each root (xa,xb) of the polynomial A(x) and B(x); a multiplier that outputs the selective signal from the chien search blocks; a counting converter unit inverting the outputs of the search blocks; a counting processor unit calculating multiplication and addition of the counting converter outputs; a constant output unit (60) that outputs the multiplicant of each of register values (C1'-C1') and polynomial coefficients.
