NEON/SIMD SVE SME and C ARM extension(ACLE,ADVSIMD,CMSE,MORELLO,MVE)

hi,

I am a little bit confused with all the different meaning.

1) NEON/SIMD SVE and SME can be used with intrinsics. But i did not found any example for SME intrinsics, just assembler.

2) C ARM Extension.

    As i anderstoud ACLE is the name for all the SIMD,SVE,SME and MVE intrinsics langauge ?

    i found this document "acle-2026Q1-2.pdf" which list all the intrinsics for SIMD,SVE,SME and MVE.

As a develloper in C i already learn how to use SIMD intrinsics. In my last post "use and utility of NPU", Peter said that i should use SME. So i anderstand that it is the last, let's said SIMD platform and so the best one.

But in fact i do not anderstand what are the difference between SIMD,SVE,SME and MVE. I read that the size of the 128-bit vectors is common to SIMD and MVE and that for SME we do not no the size. I think that it depends on the processor.

I fact i am lost whit all those different version of SIMD. I need some more explaination about what is the difference between SIMD,SVE,SME and MVE.

thanks in advance.

 i found C example of SME intrinsics in "">developer.arm.com/.../Basic-SME-example" and ">developer.arm.com/.../Basic-SME-example". But still use assembler ?
