Abstract

The invention discloses a data processing method, device and system. The method includes the steps: setting a preset number of storage areas, and determining address information of the storage area; transmitting the address information of the storage area to a terminal device; controlling the terminal device to execute reading operation or writing operation for preset number of storage areas according to the address information. A value of preset number is a natural number larger than 1. The method solves the technical problem that transmission efficiency of direct memory access is low when anexisting host transmits data through a PCIe (peripheral component interface express) interface and an FPGA (field programmable gate array).

Description

technical field [0001] The present invention relates to the field of computer technology, in particular, to a data processing method, device and system. Background technique [0002] PCI-Express (peripheral component interconnect express) is a high-speed serial computer expansion bus standard. Its original name is "3GIO", which was proposed by Intel in 2001 to replace the old PCI, PCI-X and AGP. bus standard. PCIe belongs to high-speed serial point-to-point dual-channel high-bandwidth transmission. The connected devices allocate exclusive channel bandwidth and do not share bus bandwidth. It mainly supports active power management, error reporting, end-to-end reliable transmission, hot swapping and quality of service ( QOS) and other functions. [0003] After PCI-SIG (PCI Special Interest Group) certification and release, PCIe was renamed "PCI-Express", or "PCI-E" for short. Its main advantage is the high data transmission rate, the current highest 16X 2.0 version can reac...
