METHOD AND DEVICES FOR DEVELOPING ACCESS AUTHORIZATION TO USER LEVELS FOR CLOUD-BASED FIELD-PROGRAMMABLE GATE ARRAYS

摘要

Disclosed are methods and apparatus for providing user-level access authorization for cloud-based field programmable gate arrays. An exemplary apparatus includes a field programmable gate array (FPGA) having a first memory and a second memory other than the first memory. The first memory stores a bit stream. The second memory stores a first user tag associated with the bitstream. The exemplary device further includes a kernel with an FPGA driver operatively coupled to the FPGA. The FPGA driver is for receiving a command associated with accessing the FPGA from an application executed by a user. The FPGA driver also serves to identify a second user tag associated with the command. The FPGA driver also serves to determine if the command should be accepted based on the second user tag.
