Abstract(in English) | The growing capabilities of silicon technology and the increasing complexity of applications in recent decades have forced design methodologies and tools to raise the level of design abstraction beyond register transfer level. The most popular approach has been to develop tools that use procedual languages in a C-like language. However, coarse-grain parallelism from a C program cannot be easily extracted, hence some tools use explicitly parallel languages to design hardware. But, all these tools rely on the programmer to correctly parallelize the application and perform optimizations which often needs hardware design knowledge. In this work, we propose a high-level synthesis tool for FPGAs using DSL embedded in Haskell as the design language and search program for degree of parallelism. Haskell is a pure functional language and better fit for hardware design. We implemented higher-order functions such as map, zipWith and reduce in our DSL, which allows us to automatically extract parallelism in the design. The evaluation results show that our proposed implementation achieves 3.00 and 4.96 times speed-up in two benchmarks, array addition and summation of array, respectively, relative to a C-like language design. Moreover, we also confirme that it is consistent with the result of search program for degree of parallelism. |
