Abstract
A method for sharing a memory through a plurality of routes and a device thereof are disclosed. The digital processing apparatus in accordance with an embodiment of the present invention comprises a main processor, an application processor controlled by the main processor and coupled to the main processor through one connection bus and a memory having a plurality of ports, each of which is coupled to the application processor through an independent memory bus. With the present invention, the process time for processing a high-performance, high-resolution image can be minimized, and the loss in process efficiency of the application processor can be minimized.
Claims13
A digital processing apparatus comprising:
- a main processor;
- an application processor operatively coupled to the main processor through one connection bus;
- and
- a memory, the memory having a plurality of ports, the plurality of ports being coupled to the application processor through a plurality of memory buses, each of the plurality of ports being coupled to the application processor through a separate memory bus.
A method for sharing a memory coupled to an application processor with a main processor, the method comprising:
- (a) receiving a request for writing data from the main processor;
- and
- (b) writing data in the memory through a first bus, the data corresponding to the received request for writing data,
- wherein the application processor controlled by the main processor is connected to the main processor through one connection bus;
- the memory has a plurality of ports;
- the plurality of ports are coupled to the application processor through a plurality of memory buses;
- and each port of the plurality of ports is coupled to the application processor through a separate memory bus.
