Opcode/ | Op/En | 64/32 | CPUID | Description |
|---|---|---|---|---|
| RVR | V/V | AVX512DQ | Add 16 bits masks in k2 and k3 and place result in k1. |
| RVR | V/V | AVX512DQ | Add 8 bits masks in k2 and k3 and place result in k1. |
| RVR | V/V | AVX512BW | Add 64 bits masks in k2 and k3 and place result in k1. |
| RVR | V/V | AVX512BW | Add 32 bits masks in k2 and k3 and place result in k1. |
Instruction Operand Encoding
Op/En | Operand 1 | Operand 2 | Operand 3 |
|---|---|---|---|
RVR | ModRM:reg (w) | VEX.1vvv (r) | ModRM:r/m (r, ModRM:[7:6] must be 11b) |
Description
Adds the vector mask k2 and the vector mask k3, and writes the result into vector mask k1.
Operation
