Abstract:
A data processing unit formed on a semiconductor chip for use with a rewritable graphic memory with a register, the data processing unit comprising:a circuit for outputting data to be set to the register, a first data in the data representing a first data transferring operation or a second data in the data representing a second data transferring operation;wherein when the data processing unit is responsive to a first signal, and controls the circuit so as to set the first data to the register,wherein when the data processing unit is responsive to a second signal, and controls the circuit so as to set the second data to the register,wherein the first data transferring operation is that the data processing unit transfers data of first data length to the rewritable graphic memory only one time, andwherein the second data transferring operation is that the data processing unit transfers data of first data length to the rewritable graphic memory at least two times sequentially.
