Have you ever wondered how Intel comes up with such high-quality mnemonics as VPBROADCASTMB2Q, VPCLMULHQLQDQ, and many more besides? Well, wonder no more! Here is an entirely automatic generator for you to make as many new opcodes as you please.

Disclaimers: Some generated opcodes may actually already exist. JavaScript is required. Cross-browser compatibility is not assured.

Technical Details

The opcodes are generated by sampling from a fourth-order character ngram model, trained on the entire list of Intel opcodes as extracted from a recent (as of today) NASM daily snapshot, using the SRILM toolkit. The "reverse context tree" model format is co-opted from fungot. See the source for more details.
