Description

technical field [0001] The present invention relates to a method and device for storing or reading data at high speed based on FPGA, which adopts large-scale Field Programmable Gate Array FPGA (Field programmable gate array) as a realization platform to realize data storage and transmission. The RAID controller and SATA controller are implemented in the FPGA to form a storage array, and data can be exchanged with the outside world through the camlink interface, optical fiber interface or PCIE interface. The invention relates to computer field, storage field and embedded system, and the device can be widely used in image recording and high-speed data acquisition systems, as well as system simulation. Background technique [0002] Storage technology is always a key technology in computer development. Its technical characteristics determine the data storage performance of the computer, which in turn determines the overall performance and application environment of the computer...

AI Technical Summary

Problems solved by technology

[0004] 1. RAID controller and SATA control based on application-specific integrated circuit (ASIC), low flexibility, difficult to upgrade, PCB (Printed Circuit Board) area is large, it is difficult to realize the miniaturization of equipment;

[0005] 2. The RAID controller and SATA control are based on the bus. Commands, status information and data are all transmitted through the bus, and the effective bandwidth of data transmission is low;

[0006] 3. The input and output interface is single, which cannot meet the application requirements of different occasions;

[0007] 4. The same memory is used to store runtime software code and as a high-speed data cache, without physically separating the two, causing the cache unit to become another bottleneck for high-speed data storage
