Abstract

A finite field multiplier with intrinsic modular reduction includes an interface unit (1208) that translates an n bit wide data path to a m bit wide data path where n is less than m. Also included is a finite field data unit (1204) with m bit wide registers that is coupled to a finte field control unit (1202). The finite field control unit (1202) includes a microsequencer (1402) and a finite state machine multiplier (1404). The microsequencer (1402) controls the finite state machine multiplier (1404) which performs a finite field multiply operation with intrinsic modular reduction and presents a finite field multiplication product to the finite field data unit (1204).
