Bitwise NOT Logic & Shift

not.type d, a;

Bitwise complement of an operand.

Encoding

PTX is a virtual instruction set. It has no single, stable native binary encoding — the compiler lowers this instruction to different native machine code depending on the selected NVIDIA target architecture (compute capability). This page intentionally shows no bit-diagram; see the target/version requirements below for what governs how this instruction compiles.

Syntax Forms

One mnemonic covers many type / state-space / scope / modifier combinations — each row below is an independently valid form.
