Embodiment Construction

[0051] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0052] On the one hand, the present invention provides a kind of FPGA multi-image upgrade loading method based on soft-core processor, and described method comprises the steps:

[0053] The host computer selects the image file that needs to be upgraded, and sends an upgrade start command through the interface. The protocol stack inside the FPGA parses the command information and sends it to the soft-core processor module of the FPGA. The soft-core processor module of the FPGA is upgraded according to the command. The file name and the length of the file of the mirror image, then send the message pa...

Abstract

The invention discloses an FPGA (Field Programmable Gate Array) multi-mirror upgrading-loading method based on a soft-core processor. A single FPGA way is adopted, and the soft-core processor and control modules are embedded inside to implement an interface function; a program file caching function is implemented; and a chip scale interconnected bus interface function is implemented together with a CPLD (Complex Programmable Logic Device). The upgrading-loading method is implemented by an FPGA and the CPLD. The invention also discloses an FPGA multi-mirror upgrading-loading device based on the soft-core processor. The device comprises an upper computer, an interface receiving-transmitting module, an FPGA module, an external caching module, an external storage module and a CPLD module. Through adoption of the FPGA multi-mirror upgrading-loading method and device, FPGA multi-mirror rapid upgrading and flexible loading based on different application scenes are realized.

Description

technical field [0001] The invention relates to the field of FPGA upgrade loading, in particular to an FPGA multi-image upgrade loading method and device. Background technique [0002] At present, there are two main ways to upgrade the program of FPGA (Field Programmable Gate Array, Field Programmable Gate Array): use the FPGA programmer to upgrade the FPGA program through the FPGA burning software; send the FPGA program file to the FPGA through the application software, The FPGA performs program self-upgrade through the internal RSU function. [0003] These two methods have certain limitations. The disadvantages of the first upgrade method: the upgrade speed is very slow, remote upgrade is not possible, and only single image program file upgrade is supported; the advantages and disadvantages of the second upgrade method: advantages support remote upgrade , The disadvantage is that the upgrade speed is slow, and it only supports the upgrade of a single image program file. ...
