URECPE (vector)

Unsigned Reciprocal Estimate.

Syntax

URECPE Vd.T, Vn.T

Where:

Vd
Is the name of the SIMD and FP destination register.
T
Is an arrangement specifier, and can be either 2S or 4S.
Vn
Is the name of the SIMD and FP source register.

Usage

Unsigned Reciprocal Estimate. This instruction reads each vector element from the source SIMD and FP register, calculates an approximate inverse for the unsigned integer value, places the result 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.
