- Bit Manipulation Instructions Sets (BMI) sind Befehlssatzerweiterungen für Mikroprozessoren von Intel und AMD. Es gibt mehrere Untermengen von BMI: BMI1 und BMI2 von Intel, die mit der Intel-Haswell-Mikroarchitektur eingeführt wurden sowie ABM und TBM von AMD. ABM (Advanced Bit Manipulation) beinhaltet Instruktionen aus Intels SSE4.2 und BMI1, TBM (Trailing Bit Manipulation) ist eine Erweiterung von BMI1, die mit der Piledriver-Architektur eingeführt wurde.

- Bit manipulation instructions sets (BMI sets) are extensions to the x86 instruction set architecture for microprocessors from Intel and AMD. The purpose of these instruction sets is to improve the speed of bit manipulation. All the instructions in these sets are non-SIMD and operate only on general-purpose registers. There are two sets published by Intel: BMI (now referred to as BMI1) and BMI2; they were both introduced with the Haswell microarchitecture with BMI1 matching features offered by AMD's ABM instruction set and BMI2 extending them. Another two sets were published by AMD: ABM (Advanced Bit Manipulation, which is also a subset of SSE4a implemented by Intel as part of SSE4.2 and BMI1), and TBM (Trailing Bit Manipulation, an extension introduced with Piledriver-based processors as an extension to BMI1, but dropped again in Zen-based processors).
