Modern heterogeneous FPGA architectures incorporate a variety of hardened blocks for boosting the performance arithmetic-intensive designs, such as DSP and carry blocks. Since can be configured in different ways, datapath patterns mapped into these We observe that existing high-level synthesis (HLS) tools often fail to capture some operation mapping patterns, leading limited estimation accuracy terms resource usage delay. To address this deficiency, we propose exploit graph neural networks...

High-level synthesis (HLS) can greatly facilitate the description of complex hardware implementations, by raising level abstraction up to a classical imperative language such as C/C++, usually augmented with vendor-specific pragmas and APIs. Despite productivity improvements, attaining high performance for final design remains challenge, higher-level tools like source-to-source compilers have been developed generate programs targeting HLS toolchains. These may highly HLS-ready C/C++ code,...

The past decade has witnessed increasing adoption of high-level synthesis (HLS) to implement specialized hardware accelerators targeting either FPGAs or ASICs. However, current HLS programming models entangle algorithm specifications with customization techniques, which lowers both the productivity and portability accelerator design. To tackle this problem, recent efforts such as HeteroCL propose decouple definition from essential techniques in compute, data type, memory, productivity,...
