Paper Title
High-Level Optimizations for High-Level Synthesis
Abstract
The rapidly increasing complexity of computer hardware makes impossible to design using directly HDLs.
High-level synthesis can automatically deliver optimal HDL codes from high-level programming language code. Therefore, it
becomes easier to design coprocessors, accelerators, and, in general, special-purpose hardware, in project time. Furthermore,
high-level compiler optimizations improve the quality of generated hardware descriptions in terms of performance and size.
Our high-level optimizations transform the input code, in order to generate high-performance output hardware description. In
this paper, we discuss high-level compiler-based optimizations for high-level synthesis, such as loop pipelining in the front end
of the prototype C-Cubed synthesis tool. Moreover, a novel pipelining technique that minimizes the area of the pipeline
prologue and epilogue, is analyzed. Finally, we evaluate our optimizations with synthesis results of the Livermore loops and
Mpeg2 open-source codes.
Index Terms - high-level synthesis; formal hardware synthesis; compilers; compiler optimizations; loop transformations; loop
pipelining; programming languages; hardware description languages; RTL design.
