SQABS (vector)

Signed saturating Absolute value.

Syntax

SQABS Vd.T, Vn.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 SIMD and FP source register.

Usage

Signed saturating Absolute value. This instruction reads each vector element from the source SIMD and FP register, puts the absolute value of the result into a vector, and writes the vector to the destination SIMD and FP register. All the values in this instruction are signed integer values.

If overflow occurs with any of the results, those results are saturated. If saturation occurs, the cumulative saturation bit FPSR.QC is set.

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.
