Method supporting cloud side FPGA deployment, host server and system

Abstract

The invention discloses a method supporting cloud side FPGA deployment, a host server and a system. The method comprises the following steps: dividing the FGPA into a dynamic area for processing service and a static area for establishing a data transmission channel and saving state information of the FPGA in advance, wherein the data transmission channel comprises a PCIe channel; when the engineering configured by the FPGA is changed, respectively extracting a static area file and a dynamic area file from the current engineering file, judging whether the static area file is consistent with theprevious file; if the static area file is consistent with the previous file, controlling the dynamic area to stop working, and loading the content of the dynamic area file to the dynamic area throughthe PCIe channel, starting the work of the dynamic area so as to reconfigure the dynamic area; or, reconstructing the whole FPGA through the PCIe channel. Since the PCIe channel is extremely high inbandwidth, the reconfiguration time is short; since the own PCIe channel of the FPGA is utilized, an operation of additionally configuring the JTAG external equipment is avoided, and the reconfiguration process is simplified.

Description

technical field [0001] The present invention relates to the technical field of cloud integration, in particular to a method for supporting cloud FPGA deployment, a host server and a system. Background technique [0002] At present, with the rapid development of cloud computing, more and more businesses rely on cloud processing, but the computing capacity of the cloud is limited. In the prior art, in order to improve the computing power of the cloud, an additional coprocessor is usually configured on the original host server of the cloud data center, and part of the business is handed over to the coprocessor to reduce the workload of the CPU side of the host server. Improve the overall computing power of the cloud. Since FPGA (Field Programmable Gate Array, Field Programmable Logic Gate Array) has the advantages of low energy consumption, programmable, high throughput, etc., it is usually used as a coprocessor. [0003] However, once the FPGA is configured, it can only hand...

[0003] However, once the FPGA is configured, it can only handle specific services. To enable the FPGA to handle other services, the entire FPGA needs to be reconfigured based on the JTAG (Joint Test Action Group) protocol, and the reconfiguration time is relatively short. Long, to some extent offset the effect of the FPGA used to accelerate business processing; moreover, reconfiguring the FPGA based on the JTAG protocol requires an additional JTAG cable (to establish a JTAG channel) and corresponding driver software, resulting in a cumbersome reconfiguration process
