FPGA board memory data reading method and apparatus, and medium

A device for reading memory data of a FPGA board, based on a FPGA board, comprising:

• a data feedback module configured for sending a quantity of controllers and a total quantity of DDR memories to a host end when receiving a hardware information acquisition request of the host end;
• a data slice module configured for performing data slice processing on data to be calculated based on a data space application request when the data space application request of the host end is received;
• wherein the data space application request carries a dedicated application space capacity of each DDR and the data to be calculated, and a total quantity of slices of the data to be calculated is not greater than the total quantity of the DDR memories;
• a data storage module configured for transmitting each slicing data to a corresponding DDR space;
• and
• a data reading module configured for reading data and calculating same in parallel according to a data storage position of the slicing data in each DDR.

A method for reading memory data of a FPGA board, based on a host end, comprising:

• acquiring a quantity of controllers and a total quantity of DDR memories of the FPGA board;
• determining a dedicated application space capacity of each DDR based on the total quantity of the DDR memories and the quantity of the controllers;
• and
• invoking a data request function of an open computing language (Opencl) to send a data space application request to the FPGA board, wherein the data space application request carries a dedicated application space capacity of each DDR and data to be calculated, so that the FPGA board performs data slice processing on the data to be calculated and stores a corresponding DDR space.
