Abstract
A data processing device exchanges data between a memory and an external bus master. The memory is connected to the data processing device via a first bus so as to store data. The external bus master is connected to the data processing device via a second bus so as to process data. The data processing device comprises a bus-transmission control unit accessing the memory via the first bus in response to a request to access the memory made by the external bus master via the second bus.
Claims16
A data processing device for exchanging data between a memory and an external bus master, the memory connected to the data processing device via a first bus so as to store data and the external bus master connected to the data processing device via a second bus so as to process data, the device comprising:
- a bus-transmission control unit accessing said memory via said first bus in response to a request to access said memory made by said external bus master via said second bus.
A data processing method for exchanging data between a memory and an external bus master, the memory connected to a first bus so as to store data and the external bus master connected to a second bus so as to process data, the method comprising:
- the first step of accessing said memory via said first bus in response to a request to access said memory made by said external bus master via said second bus.
A data processing system having a memory connected to a first bus so as to store data and a second data processing device connected to a second bus so as to process data, the system comprising:
- a first data processing device connected to said first bus and said second bus so as to access said memory via said first bus in response to a request to access said memory made by said second data processing device via said second bus.
