Automating the design of mLUT MPSoPC FPGAs in the cloud

Modern platform FPGAs are over the million-LUT level, large enough to support complete heterogeneous Multiprocessor System-On-Chips (MPSoCs). Constructing systems with 10´s of processors is currently feasible using existing manual methods within vendor-specific CAD tools. However these manual, by-hand, approaches will not be feasible for constructing future systems with 100´s to 1,000´s of processors. Instead, new automated system assembly approaches will be required to handle these levels of system complexity and diversity. In this paper we present a new automated design flow for creating such next generation heterogeneous MPSoCs. An integral part of the MPSoPC system created is the inclusion of a general purpose PThreads-compliant HW/SW co-designed operating system and heterogeneous compiler. Our design flow has been placed in the cloud and is freely accessible across the Internet.
