Hardware synthesis of complex standard interfaces using CAL dataflow descriptions

This paper presents a contribution to the development of rapid prototyping tools based on data-flow description. In this context, the efficiency of automatic translator tools from the data-flow description to C and/or HDL are presented using two design cases. Moreover, this paper presents the novel concept of the automatic synthesis of interfaces based on dataflow description. Such “generic” interfaces include an embedded microprocessor, which enables using a vide variety of interfaces already available as optimized libraries from the FPGA manufacturers. The different design cases described have been tested and validated on different platforms. The results of the work show the flexibility and generality of the proposed wrapper methodology that is described in the paper.
