ABSTRACT:
A data processing apparatus executing in a pipelined manner a plurality of instruction including first and second instructions, the first instruction having first register address information and the second instruction having a second register address information, the data processing apparatus has a register file 110 including a plurality of registers, execution means 117, 118 for receiving and executing the first instruction to produce memory address information in a first pipeline cycle and for receiving and executing the second instruction to produce processed data, which is to be stored in the register file 110, in a second pipeline cycle succeeding to the first pipeline cycle, a memory circuit including a data memory 124 and an access control circuit reading out memory data, which is to be stored in the register file, from a memory area of the data memory 124 designated by the memory address information in the second pipeline cycle, and control means 133 for allowing the processed data to be stored in the register 110 file and preventing the memory data from being in the register file when the first register address information is coincident with the second register address information.
