Abstract

The embodiment of the invention provides an FPGA-based communication method and device, a host and a heterogeneous acceleration system. In the embodiment of the invention, the host and an FPGA-based acceleration device in the heterogeneous acceleration system perform cooperative work by adopting a mechanism of the working queue and the completion queue, so that the interaction process is simplified. The request commands from the host and the completed state information from the acceleration device are stored in different working queues, namely different storage areas, so that the read-write competition caused by simultaneous reading or writing of the same storage area in the communication process of the host and the acceleration device based on the FPGA is avoided, and the communication efficiency can be effectively improved.

Description

technical field [0001] The present application relates to the technical field of data transmission, and in particular to an FPGA-based communication method, device, host and heterogeneous acceleration system. Background technique [0002] With the development of big data and artificial intelligence, the demand for computing is rising rapidly, and the workload of software is increasing rapidly, which requires processors to provide better performance in the face of high-intensity data processing tasks. However, general-purpose processors need to take into account both calculation and control, which leads to general-purpose processors with strong computational versatility but average computational performance. To solve this dilemma, Field-Programmable Gate Array (FPGA) can be used as a coprocessor of a general-purpose processor for heterogeneous acceleration. [0003] The main principle of heterogeneous acceleration is: data sharing and moving among multiprocessors, and exchan...
