Which features did SVE2 inherit from SVE?
SVE2 inherits the fundamental architecture features of SVE, including the vectors, system control registers, and instructions.
-
What are the vectors for SVE2?
SVE2 uses the same SVE Z0-Z31 vectors, P0-P15 predicate registers, and FFR predicate register that SVE uses.
-
How many bits can SVE2 vectors have?
Z0-Z31 can be implemented from 128 bits up to 2048 bits, with 128 increment.
-
What features does SVE2 enable, in addition to those added by SVE?
SVE was designed for HPC. SVE2 extends the SVE instruction set to address the requirements in application areas like general-purpose software, web-serving server, computer vision, multi-media, LTE baseband process, genomics, and in-memory databases.
-
What are the advantages of SVE2 compared to a traditional SIMD instruction set, for example Neon?
The advantages of SVE2, compared to Neon, include:
o SVE2 programs can be built once and run on hardware with various vector lengths.
o SVE2 has more vectorization flexibility.
o SVE2 extends the instruction set enabling more application areas.
