IntelLabs/encrypted-computing-sdk

Intel’s HERACLES accelerator introduces a new set of fundamental instructions, the Polynomial Instructions Set Architecture (P-ISA) that operates directly on polynomials requiring a completely new programming environment. This open-source project aims at developing the building blocks for a compiler toolchain for HERACLES.

The SDK implements a modular, LLVM-inspired compiler pipeline with language-independent intermediate representations (IRs) that decompose large polynomial computations into abstraction layers, enabling target-agnostic FHE scheme development and third-party library integration. It includes P-ISA tools and an assembler targeting Intel's HERACLES accelerator, which accelerates polynomial operations via SIMD instructions while minimizing memory-compute data movement—a key bottleneck in traditional FHE implementations. Currently in Phase 1 with functional prototypes, the project aims to reduce the performance overhead confining FHE to specialized use cases.
