pub unsafe fn __usada8(a: int8x4_t, b: int8x4_t, c: u32) -> u32

🔬This is a nightly-only experimental API. (stdarch_arm_dsp #117237)

Available on ARM only.

Sum of 8-bit absolute differences and constant.

Returns the 8-bit unsigned equivalent of

res = abs(a[0] - b[0]) + abs(a[1] - b[1]) +
(a[2] - b[2]) + (a[3] - b[3]) + c
