Abstract
A data processing device having a PC controlling part for executing an operation of branch which has a first register for holding a result of decoding in an instruction decode unit, a register for holding a description indicating an execution condition of the operation (a value of field for designating condition), and a register for holding the description indicating a time for executing the operation (an address value of PC), wherein the execution condition is started when a value held in the register is in agreement with a PC value in accordance with the description of the register; and if the condition is satisfied, the PC controlling part executes the operation based on a content held in the register, whereby it is possible to delay the time for judging the execution condition during this delay, to thereby increase a degree of freedom in scheduling instructions such that the branch instruction is positioned prior to the operation instruction for determining the execution condition in the program.
