20.241 UMIN (vector)

Unsigned Minimum (vector).

Syntax

UMIN Vd.T, Vn.T, Vm.T

Where:

Vd: Is the name of the SIMD and FP destination register.
T: Is an arrangement specifier, and can be one of 8B, 16B, 4H, 8H, 2S or 4S.
Vn: Is the name of the first SIMD and FP source register.
Vm: Is the name of the second SIMD and FP source register.

Usage

Unsigned Minimum (vector). This instruction compares corresponding vector elements in the two source SIMD and FP registers, places the smaller of each of the two unsigned integer values into a vector, and writes the vector to the destination SIMD and FP register.

Depending on the settings in the CPACR_EL1, CPTR_EL2, and CPTR_EL3 registers, and the current Security state and Exception level, an attempt to execute the instruction might be trapped.
