Problems solved by technology

If the number of terminals in the system is large and the amount of interactive data between terminals is large, the existing solution still requires the CPU to frequently enter the DMA to start and terminate the process, which will increase the CPU load and reduce system efficiency.

Abstract

The invention provides a data exchange method and device based on FPGA. The method comprises the following steps: a virtual P2P bridge in an FPGA module receives a TLP type data packet sent by a firstterminal and stores the data packet in a buffer unit; The service unit in the FPGA module parses the data packet, obtains the destination terminal address and address route corresponding to the datapacket, and determines the second terminal according to the destination terminal address. the state of the bus connected between the second terminal and the FPGA module is judged; When it is determined that the state of the bus is in the idle state, the data packet is read from the buffer unit and sent to the second terminal through the virtual P2P bridge.

Description

technical field [0001] The present application relates to the technical field of data interaction, in particular to an FPGA-based data interaction method and device. Background technique [0002] PCIe bus technology is the third generation I / O technology replacing PCI, also known as 3GIO. The PCIe bus is a high-performance, general-purpose I / O interconnection bus defined for future computer and communication platforms. The PCIe bus is a serial bus, using point-to-point transmission, each transmission channel has exclusive bandwidth, and the transmission rate is high. Point-to-point transmission reduces the complexity and difficulty of system hardware platform design, thereby reducing system cost and improving system cost performance and robustness. However, with the increasing system performance, functions and bandwidth, more external devices are required to be connected to the CPU. However, the number of PCIe ports on the CPU itself is limited. You can use a PCIe switch ...
