ABSTRACT:
A method for accessing a device, such as a memory device and an interface device, by a processor is disclosed. The method involves the processor requesting access permission for the transfer of data. The bridge device grants access permission. The processor in response to the granting of access permission indicates that the processor is busy with the access. The processor also generates address and control signals for the access. The bridge device indicates that data is ready for transfer. A processing system including the processor and the bridge device is also disclosed.
