Arithmetic operation
SMULL
Signed multiplication in scoring, ranking, and fixed-width arithmetic flows.
Signature
| Raw symbols | FHE16_SMULL |
|---|---|
| Example | int32_t* out = FHE16_SMULL(a, b); |
Caller
Signed multiplication in scoring, ranking, and fixed-width arithmetic flows.
Circuit Path
Homomorphic pathDADDA partial-product multiplier. A 1-bit input delegates to FHE16_ANDVEC.
Input, Output, Ownership
| Output | n-bit signed product ciphertext. |
|---|---|
| Ownership | Returned ciphertext is caller-owned. |
| Implementation baseline | FHE16Ver6/include/soAPI/soAPI.hpp and FHE16Ver6/src/soAPI/soAPI.cpp |
C Example
int32_t* out = FHE16_SMULL(a, b);
FHE16_Free(out);
