Advantages of RISC-V vector processing over x86 style SIMD

Instead of adding SIMD instructions such as MMX, SSE, AVX or Neon, RISC-V designers are focusing on vector processing.

A well known way of processing multiple streams of data in parallel is through the use of SIMD instructions. All major chip makers started adding SIMD instructions to their processors in the late 1990s. MMX was added to Intel’s Pentium processor in 1997. It was intended to accelerate image, audio and video processing.
