SUMMARY:Late Breaking Results: A High-Performance TFHE Bootstrapping Accel
 erator with Heterogeneous Processing Engines
DESCRIPTION:Haopeng Zhang and Yukui Luo (Binghamton University), Jiafeng X
 ie (Villanova University), and Wenfeng Zhao (Binghamton University)\n\nThi
 s paper presents a high-performance programmable bootstrapping (PBS) accel
 erator for privacy-preserving computation under Torus Fully Homomorphic En
 cryption (TFHE) scheme. The proposed design features a heterogeneous proce
 ssing architecture, including a barrel-shifter-based polynomial rotation u
 nit, integer processing elements (PEs) for level decomposition, and comple
 x-number arithmetic PEs for polynomial multiplication. Our proposed design
  completes one PBS in 47𝜇s, which is over 8×latency reduction while consum
 ing comparable hardware resources compared to state-of-the-art designs.\n\
