Problems solved by technology

[0003] However, in the related art, since the FPGA is pre-swapped into resource blocks of fixed size, when the accelerator specified by the user does not match the pre-divided area, resources are wasted or even unusable, and communication between accelerators cannot be supported. Expansion, resulting in poor scalability of the entire system, cannot be flexibly applied to cloud computing scenarios, and needs to be improved

Abstract

The invention discloses a FPGA (field-programmable gate array) virtualized hardware architecture communication method and device. Multiple resource blocks are divided in a FPGA virtualized hardware architecture and are in mutual communication through a data channel. The method includes: acquiring configuration information needed by multiple users; acquiring distribution information according to the configuration and resource block dividing information; configuring at least one resource block into corresponding acceleration regions virtualized to the users according to the distribution information. The resource blocks can be simultaneously divided to the same user according to the data channel, requirement on flexibility is met, FPGA utilization rate is increased, and FPGA calculated performance is increased.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a communication method and device for a virtualized hardware architecture of FPGA. Background technique [0002] At present, the system structure in the related art and the dynamic reconfiguration area division on the FPGA (Field-Programmable Gate Array, Field Programmable Gate Array), the FPGA will be pre-changed into resource blocks of fixed size, and each resource block can be configured into a dedicated hardware accelerator and be virtualized to different users in the cloud. [0003] However, in the related art, since the FPGA is pre-swapped into resource blocks of fixed size, when the accelerator specified by the user does not match the pre-divided area, resources are wasted or even unusable, and communication between accelerators cannot be supported. Expansion leads to poor scalability of the entire system and cannot be flexibly applied to cloud computing s...
