Peripheral access with synchronization feature

摘要

A data processing apparatus includes control circuitry (15, 73) connectable to a peripheral device (17) for performing an access of the peripheral device, and data processing circuitry (13) connected to the control circuitry. The control circuitry includes synchronizing circuitry (29, 77) for synchronizing the control circuitry with the data processing circuitry after completion of the peripheral access.
