Although recently proposed post-quantum cryptography (PQC) is secure against both classical and quantum computers, existing embedded systems cannot support the PQC algorithms due to their large key sizes and complex arithmetics. High-level synthesis (HLS) helps hardware accelerator designs, but current HLS frameworks fail to produce efficient designs due to duplicated logics for repeatedly invoked functions with pointer arguments. This work proposes a new logic deduplication scheme with decentralized pointer analyzers in HLS for the PQC algorithms. The proposed scheme reduces logic areas by efficiently resolving memory accesses in commonly invoked logics and sharing the common logics without delaying latency.
