20.21 CMHI (vector, register)

Compare unsigned Higher (vector).

Syntax

CMHI 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, 4S or 2D.
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

Compare unsigned Higher (vector). This instruction compares each vector element in the first source SIMD and FP register with the corresponding vector element in the second source SIMD and FP register and if the first unsigned integer value is greater than the second unsigned integer value sets every bit of the corresponding vector element in the destination SIMD and FP register to one, otherwise sets every bit of the corresponding vector element in the destination SIMD and FP register to zero.

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.
