Abstract

The invention discloses a method and system for USB communication between a computing device and an FPGA. The method comprises the following steps: actually connecting a computing device end USB chip and an FPGA end USB chip through a USB bus; connecting the computing device end USB chip with a device driving program and connecting the FPGA end USB chip with an FPGA communication system hardware program; connecting the computing device driving program with a computing device user software program through a communication interface and connecting the FPGA communication system hardware program with an FPGA user hardware program through a communication interface; realizing the virtual connection between the computing device driving program and the FPGA hardware program through the actual connection of a USB bus, so as to realize the virtual connection between the computing device user software program and the FPGA user hardware program; and realizing the connection between the computing device and FPGA hardware through a communication interface. The method and system are capable of providing efficient, reliable and strong-interactivity data communication between the computing device and the FPGA, and are high in universality.

Description

technical field [0001] The invention belongs to the field of computer communication, relates to FPGA (Field Programmable Gate Array), in particular to an efficient, reliable and highly interactive USB communication method and communication system between computing equipment and FPGA. Background technique [0002] FPGA (Field-Programmable Gate Array, Field-Programmable GateArray) is a programmable high-performance semi-custom circuit device. With the development of chip technology, the performance of FPGA has been continuously improved and its functions have been gradually improved. Therefore, it has been developed by more and more Researchers and researchers use it as an accelerator in a computer system. Although the existing FPGA provides users with high-speed interfaces such as PCIe and 10 Gigabit Ethernet, it also limits the size of the computer case, and the user has to carry a large-size case. Complete the communication between the computer and the FPGA. High-speed, po...
