Abstract

The invention relates to a data cache method and device and a data transmission system. The data cache device comprises a first cache module, a second cache module and a third cache module, which areconnected in sequence, wherein the first cache module is connected with a random access memory; and the third cache module is connected with a data processor. The system depends on a data locality principle, so that a waiting problem caused by broadband mis-matching between random access memories and data processors is avoided, and on the basis of satisfying the data locality, the data reading / writing efficiency between a plurality of data processors and between the plurality of data processors and the random access memories is improved through mining parallel operation.

Description

technical field [0001] The present disclosure relates to the technical field of data processing, and in particular to a data caching method, device and data transmission system. Background technique [0002] In the development of computer systems over the past 10 years, the improvement of computing power has been far greater than the improvement of memory bandwidth, so the gap between memory performance and computing performance is gradually expanding. This is also a challenge that deep neural network accelerators usually face. The high-bandwidth local cache, which relies on the principle of data locality, can solve the mismatch between memory bandwidth and computing power to a certain extent. Contents of the invention [0003] Embodiments of the present disclosure provide a data caching method, device, and data transmission system. Described technical scheme is as follows: [0004] According to a first aspect of an embodiment of the present disclosure, there is provide...
