Towards the Inclusion of FPGAs on Commodity Heterogeneous Systems

Nowadays, most commodity heterogeneous systems consist in either a CPU+GPU or CPU+FPGA. An attractive alternative consists in merging both in a new class of heterogeneous system: CPU+GPU+FPGA in order to combine the advantages of all of them into a single platform. In a three-device heterogeneous system, similarly to a two-device system, we have to face problems like: programmability versus device performance, data-buffers management and workload distribution. In this work, we present the first steps into a runtime which deals with theses problems for a system with a CPU+GPU+FPGA.
