Abstract
Field Programmable Gate Arrays (FPGAs) are attractive
platforms for applications with high computational demands
and low energy consumption requirements. However, the
design effort for FPGA development remains high in comparison
to that for software development. High-level synthesis (HLS)
tools are meant to ease the process of FPGA development by
generating hardware designs from high level languages such
as C/C++. However, they do not always produce high quality
designs, especially for applications that can not be automatically
parallelized easily. In this report we study existing research work
aimed at improving different steps in the HLS process towards
better exploiting instruction-level parallelism (ILP) and easing
the design process. We conclude with a proposal for a research
direction we intend to take toward
