SVE vs SVE2

SVE2 inherits the fundamental architecture features of SVE, including the vectors, system control registers, and instructions.

SVE2 uses the same SVE Z0-Z31 vectors, P0-P15 predicate registers, and FFR predicate register.

Z0-Z31 can be implemented from 128 bits up to 2048 bits (with 128 increment).

While SVE was designed for HPC, SVE2 extends the SVE instruction set to address the requirements in application areas such as general-purpose software, web-serving server, computer vision, multi-media, LTE baseband process, genomics, and in-memory database.

The advantages of SVE2, compared to Neon, include:

• SVE2 programs can be built once and run on HW with various vector lengths
  
  
• SVE2 has more vectorization flexibility
  
  
• SVE2 extends the instruction set enabling more application areas
