A novel garbled circuit (GC) accelerator and compiler, named HAAC, mitigates performance overheads and makes privacy-preserving computation more practical. HAAC is a hardware-software co-design. GCs are exemplars of co-design as programs are completely known at compile time because all dependence, memory accesses, and control flow are fixed. The compiler can leverage its program understanding to realize hardware's performance potential by generating effective instruction schedules, data layouts, and managing off-chip events. Arbitrary GC programs may be expressed as streams, which simplifies hardware, and the development of an adaptive, on-chip scratchpad that tracks program execution to capture data reuse despite the lack of a regular access pattern or requiring tagging.
