摘要 |
The present invention discloses a system and a method for data transmission. The system includes: a plurality of graphics processing units; a global shared memory for storing data transmitted among the plurality of graphics processing units; an arbitration circuit module, which is coupled to each of the plurality of graphics processing units and the global shared memory and configured to arbitrate an access request to the global shared memory from respective graphics processing units to avoid an access conflict among the plurality of graphics processing units. The system and the method for data transmission provided by the present invention enable respective GPUs in the system to transmit data through the global shared memory rather than a PCIE interface, thus saving data transmission bandwidth significantly and further improving a computing speed. |
