Dcc

Participants : Christophe Alias, Alexandru Plesco [Compsys/Zettice] .

Dcc (DPN C Compiler) is the front-end of the HLS tool transferred to the start-up Zettice (see Section  7.3 ). Dcc takes as input a C program annotated with pragmas and produces an optimized data-aware process network (DPN). A DPN is a regular process network that makes explicit the I/O transfers and the synchronizations. Dcc features throughput optimization, communication vectorization, and automatic parallelization. Furthermore, Dcc applies analysis to build the DPN circuitry: multiplexing, channels sizing and allocation, FSM generation. To do so, Dcc uses extensively the analysis implemented in PoCo (Section  5.5 ), in particular dataflow analysis and control generation, and Bee (Section  5.6 for buffer sizing. The DPN specific analysis of Dcc is currently under patent deposit.

Dcc represents more than 3000 lines of C++ code.
