摘要
PURPOSE: A polynomial basis based binary parallel multiplier, a method thereof, and a microprocessor using the same are provided to reduce space complexity and to minimize increment of time complexity. CONSTITUTION: A first AND operation unit(210) of a subtractor(200) proceeds multiplication of a coefficient of an element B coping with first multiplication matrices which are used for forming a subtraction result value using a module of S1. A second AND operation unit(220) proceeds multiplication of the coefficient of the element B coping with a second multiplication matrices which are used for forming the subtraction result value using a module of S2. A third AND operation unit(230) proceeds the multiplication of the coefficient of the element B coping with a third multiplication matrices using a module of S3. A unit(260) for generating AB multiplication value creates the subtraction result value of the module of S by proceeding an exclusive OR operation.
