High-speed transmission method based on PCIE interface, storage medium and terminal

Abstract

The invention discloses a high-speed transmission method based on a PCIE interface, a storage medium and a terminal, and the method comprises the steps: judging whether a function library exists in anFPGA prototype verification development board or not, and initializing the function library after judging that the function library exists; calling a device to search and open an interface, enumerating all PCIe devices in the current terminal, and opening an equipment CAPI; carrying out register reading and writing on the designated address, then, judging whether data comparison is correct or notaccording to a reading and writing result, if so, carrying out DMA transmission on the designated address, carrying out comparison and processing on the data, and then, turning off the equipment CAPI; and if the data comparison result is judged to be wrong, directly closing the equipment CAPI and stopping transmission, so that a large amount of data can be transmitted between a host and a prototype at a high speed, the real-time test is approached, the user design can be executed at a hardware speed, the design verification is accelerated, the test coverage of FPGA prototype verification is increased, and the problems proposed in the background technology can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of data transmission, in particular to a high-speed transmission method based on a PCIE interface, a storage medium and a terminal. Background technique [0002] FPGA prototype verification development board is a circuit board used for embedded system development, including a series of hardware components such as central processing unit, memory, input device, output device, data path / bus and external resource interface. Development boards are generally customized by embedded system developers themselves according to development needs, and can also be researched and designed by users themselves. The development board is for beginners to understand and learn the hardware and software of the system. At the same time, some development boards also provide the basic integrated development environment, software source code and hardware schematic diagram. Common development boards include 51MCU, ARM, FPGA, and DSP ...

AI Technical Summary

Problems solved by technology

[0003] In the process of development and design of the development board, a large amount of data needs to be transmitted at high speed between the host computer and the design prototype, so as to be used for real-time testing and execution of user design, so higher requirements are placed on the transmission efficiency of the interface, while the existing technology Sometimes the transfer rate of the development board interface cannot meet the requirements
