SVE(Scalable Vector Extension)

armv7 까지는 NEON 이고 armv8 부터는 SVE 라고 이름이 달라지는 듯

 

Scalable Vector Extension (SVE) is a vector extension the A64 instruction set of the Armv8-A architecture. Armv9-A builds on SVE with the SVE2 extension. Unlike other SIMD architectures, SVE and SVE2 do not define the size of the vector registers, but constrains it to a range of possible values, from a minimum of 128 bits up to a maximum of 2048 in 128-bit wide units. Therefore, any CPU vendor can implement the extension by choosing the vector register size that better suits the workloads the CPU is targeting. The design of SVE and SVE2 guarantees that the same program can run on different implementations of the instruction set architecture without the need to recompile the code.
