Providing of FPGA Resources as a Service: Technologies, Deployment and Case-Study

In this study we analyzed some aspects of applying the Field Programmable Gate Array (FPGA) technology based on Peripheral Component Interconnect Express (PCIe) bus to create a cloud service. Task classification for a FPGA as a Service (FaaS) was proposed. We considered various approaches to FaaS deploying and feasible ways of communication between the cloud infrastructure and the FPGA platform. We elaborated and approved cost-effective FaaS architecture, which is based on a set of FPGA boards. The input-oriented task based on brute force search of polynomials for nonlinear feedback shift registers of the second degree was implemented. The approach of creating multiparametrized tasks for a wide range of FPGA resources was proved to be effective.
