A few lines of code, thousands of cores: High-level FPGA programming using vector processor networks

MORA-C++ is a novel, high-efficiency FPGA dataflow programming framework. The framework, which consists of a compile-time configurable network of Vectorized Processors-in-Memory (PIM) cores, is programmed using a high-level C++ API. In this paper we present our work on support for vectorized cores and variable-size data path widths. Measurement results on our implementation for the SGI RC-100 platform show that, by instantiating over a thousand customized cores, the MORA-C++ framework can achieve throughputs very close to the I/O bandwidth of the system for a high-performance DCT application.
