Intel ADX (Multi-Precision Add-Carry Instruction Extensions) is a set of extensions to the x86 instruction set architecture for arbitrary-precision arithmetic. It was introduced as part of the Broadwell microarchitecture.[1][2]
New instructions
The instruction set extension contains just three new instructions, though MULX from BMI2 is also considered part the large integer arithmetic support.[3]
| Instruction | Description |
|---|---|
ADCX
|
Adds two integers with carry set and read from the carry flag. |
ADOX
|
Adds two integers with carry set and read from the overflow flag. |
SBB
|
Subtract one integer from another, and set and read carry/burrow from the carry flag. |
