• Rounding floats to integers on Cortex-M4
    I've encountered an odd problem on STM 32F4xx CPU with hardware FPU enabled: When rounding floats to integers, compiler always uses VCVT (round towards zero) instruction instead of VCVTR (round using...

  • 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...
