Abstract: In the resolver control system,we often use the trigonometric transformation function which means SIN/COS Multiplication is indispensable.In order to improve precision and velocity of resolver control circuit,the simulation of signal from an engine will be placed into the control system for analyzing and handling.This article is focus on the design of cosine and sine Multiplication,which the signal from regular ROM lookup table is multiplied by the signal processed by sigma delta sampling method.This article also will go through the detail from the resolver control system to delta sampling method and regular ROM lookup table algorithm.Since the structure of the design is well distinct described by verilog,and the circuit has been verified experimentally,it will take advantage of integrating the control system circuit.

Key words: resolver, RDC, SIN/COS multiplication, ROM table
