Bit-shift Integer Rounding-to-even with ARMv8 NEON SIMD on Aarch64

UQRSHRN can be used to do bit shifting with rounding. However it looks like the rounding behavior is always rounding to nearest integer.. but in case of ties rounds away from 0. Is there a way to control...

NEON multiplying 8-bit vector with 16-bit scalars

Hi, I'm experimenting with NEON on a i.mx7d SoC. I'm trying to do the following calculation. I've got 8 RGB pixels stored in a vector. uint8x8x3_t rgb I then want to calculate: rside=R*19*19...
