Generalized universal programmable quantum processor to the d-level quant um system and a explicit scheme to implement a universal gate array is given. Th i s universal gate array consists of a joint Bell measurement and three controlled -NOT gates. In order to complete the Bell measurement and the controlled-NOT o peration for the d-level quantum system, we have introduced the generalized Bel l bases and generalized controlled-NOT operation for qudits, and discussed the properties of the generalized Bell basis states and controlled-NOT gate.
