RESUMO

ChipCflow is a tool for algorithms execution using a data dynamic flow in reconfigurable hardware. The main purpose of the work is to use the data flow architecture model, associated to the concept of reconfigurable architectures, to speed up C written applications. The program acceleration happens in the most intensive processing parts (example: loops), through direct hardware execution, using to advantage of the natural parallelism of the data flow model. The C conversion module in data flow graph is the basic part in the development of the ChipCflow project and the specific objective of the developed work. In this work we present detais of the C precompiler that generates VHDL code for the data flow operators modules of the written program of the original application in C. It is possible to consider as the main result of this thesis, the implementation of algorithms from a C language in the data flow graph model proposed in the project ChipCflow, where the operators to the data stream are typically already known, and even the way interconnection too, but how to approach the implementation in VHDL, and as a dynamic data flow, makes the proposed model for both the hardware and the compiler, a feature only available so far.
