Abstract
An input/output unit communicates with a memory located outside a data processing device to provide a sub-processing function to perform data processing using a memory located inside the data processing device and a memory located outside the data processing device. Delay due to access to the memory located outside the data processing device by a processing unit of the data processing device may be reduced, and processing performance by the data processing device may be improved.
Claims20
A data processing device comprising:
- a first memory;
- a processing unit configured to communicate with the first memory through a first signal line, and to perform first data processing using the first memory and an external second memory;
- and
- an input/output unit configured to communicate with the first memory through a second signal line, to transfer data that is transmitted and received between the processing unit and the external second memory, and to perform second data processing using at least one of the first memory or the external second memory.

A data processing system comprising:
- an external memory disposed on a substrate;
- and
- a data processing chip disposed on the substrate, and configured to communicate with the external memory,
- the data processing chip comprising:
- an internal memory;
- a processing unit configured to perform first data processing using the internal memory and the external memory;
- and
- an input/output unit configured to transfer data to be transmitted and received between the processing unit and the external memory, and to perform second data processing using at least one of the internal memory or the external memory.
