Abstract
A data processing device includes a program execution section to supply an operation direction signal to a peripheral device based on an executed program and execute a branch operation in response to a branch direction signal, and a branch wait operation section to receive the branch direction signal and a peripheral device status notification signal indicating whether an operation performed in the peripheral device is being executed. The branch wait operation section outputs an instruction issue stop signal directing waiting of the branch operation to the program execution section if the branch direction signal is input during a period when the peripheral device status notification signal is active indicating that the operation in the peripheral device is being executed.
