Data migration system and method

Abstract

The invention provides a data migration system and method. The system comprises a control transfer module, an interface conversion module and a DDR data cache module. The control transfer module is connected with the storage module through the interface conversion module; the controll transfer module writes the first configuration data into the SD card; when each system starting file data block which is fed back by the SD and corresponds to the SD card reading instruction in the first configuration data is received, the SD card is started; a file data block for each system is started; whetherdata is valid data is determined, and if yes, a bus write time sequence signal corresponding to the system startup file data block is generated, a bus write address corresponding to the system startupfile data block is determined, and when the enable signal is enabled, the bus write time sequence signal and the bus write address are sent to a DDR data cache module for storage through an interfaceconversion module. By applying the method provided by the invention, data migration based on hardware is realized, time delay of the data between the CPU and the system bus is avoided, and the data migration speed is increased.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data migration system and method. Background technique [0002] BOOM (Berkeley Out-of-Order Machine) is a processor based on the fifth-generation reduced instruction set architecture RISC-V. Compared with traditional processors, it has the functions of out-of-order launch and out-of-order execution. [0003] The BOOM processor can be set in the system in the form of a chip or FPGA prototype platform. In the prior art, it is a common method to boot the BOOM processor system from the SD card. Booting the BOOM processor system from the SD card requires the SD The system startup file data in the card is migrated to the DDR data cache module in the BOOM processor system to run. The files to be moved include FSBL, DTB, BBL, and KERNEL, among which KERNEL is a LINUX kernel file.

[0003] The BOOM processor can be installed in the system in the form of a chip or FPGA prototype platform. In the prior art, it is a common The method of booting the BOOM processor system from the SD card needs to migrate the system startup file data in the SD card to the DDR data cache module in the BOOM processor system to run. The files to be moved include FSBL, DTB, BBL, and KERNEL. KERNEL is a LINUX kernel file, and the file is relatively large. In the existing data migration method, the CPU controls the driver software to move the system startup file data in the SD card to the DDR data cache module. Because the system startup file is large, it is controlled by the CPU. The driver software moves the system startup file data to DDR at a slow speed and low efficiency
