9. An operating method of a data processing system, the method comprising:
-
sending, by a first processing unit of the data processing system, a command to a second processing unit of the data processing system through a first interface and sending, by the first processing unit, input data to a third memory unit of the data processing system through a second interface; receiving, by the second processing unit, the input data from the third memory unit through a third interface, processing the input data in response to the command to generate process data, and sending the process data to the third memory unit through the third interface; and receiving, by the first processing unit, the process data from the third memory unit through the second interface. - View Dependent Claims (10)

11. An operating method of a data processing system, the method comprising:
-
sending, by a first processing unit of the data processing system, a command to a second processing unit of the data processing system through a first interface, sending, by the first processing unit, first input data to a second memory unit of the data processing system through the first interface, and sending, by the first processing unit, second input data to a third memory unit of the data processing system through a second interface; receiving, by the second processing unit in response to the command, the first input data from the second memory unit, processing the first input data to generate the first process data, and sending the first process data to the second memory unit; receiving, by the second processing unit through the third interface in response to the command, the second input data from the third memory unit, processing the second input data to generate second process data, and sending the second process data to the third memory unit; and receiving, by the first processing unit, the first process data from the second memory unit through the first interface and receiving, by the first processing unit, the second process data from the third memory unit through the second interface.

12. An operating method of a data processing system comprising a third memory unit including first and second memory regions, the operating method comprising:
-
sending, by a first processing unit of the data processing system, a command to a second processing unit of the data processing system through a first interface, sending first input data to a second memory unit of the data processing system through the first interface, and sending second input data to the first memory region through a second interface; receiving, by the second processing unit in response to the command, the first input data from the second memory unit, processing the first input data to generate the first process data, and sending the first process data to the second memory unit; receiving, by the second processing unit through the third interface in response to the command, the second input data from the first memory region, process the second input data to generate second process data, and sending the second process data to the second memory region; and receiving, by the first processing unit, the first and second process data from the second memory region through the second interface.
