ABSTRACT:
The present invention is directed to a method and a device for memory share by a plurality of processors. The portable terminal according to an embodiment of the present invention comprises a main memory; a sub-control unit coupled to the main memory through bus #1,the sub-control unit processing and storing raw data in accordance with a process order, the raw data being stored in the main memory, the main memory being accessed through bus #1;and a main control unit coupled to the main memory through bus #2and coupled to the sub-control unit independently through bus #3,the main control unit transmitting said process order to the sub-control unit through bus #3.The present invention can prevent the weakening of processing power or the bottleneck problem during the process of information transmission between the memory and a plurality of processors.
