While FPGA-based hardware accelerators have repeatedly been demonstrated as a viable option, their programmability remains a major barrier to their wider acceptance by application code developers. These platforms are typically programmed in a low level hardware description language, a skill not common among application developers and a process that is often tedious and error-prone. Programming FPGAs...
Branch prediction is an important topic in modern computer architecture research. Predictors attempt to improve the performance of a processor with a reasonable hardware cost. In the last decade, many prediction schemes have been developed in order to achieve this objective, each of them with different cost/performance tradeoffs. Identifying the optimal predictor for a given architecture and set of...
The MPEG Reconfigurable Video Coding working group is developing a new library-based process for building the reference codecs of future MPEG standards, which is based on dataflow and uses an actor language called CAL. The paper presents a code generator producing RTL targeting FPGAs for CAL, outlines its structure, and demonstrates its performance on an MPEG-4 Simple Profile decoder. The resulting...
The Kiwi system is targeted at making reconfigurable computing technology accessible to software engineers that are willing to express their computations as parallel programs. Our kiwic compiler takes .NET assembly language with suitable custom attributes as input and produces Verilog output which is mapped to FPGAs. In this brief paper, we describe attributes used to mark up I/O nets, embed assertions,...
