FRSQRTE

Floating-point reciprocal square root estimate (unpredicated).

Find the approximate reciprocal square root of each active floating-point element of the source vector, and place the results in the corresponding elements of the destination vector. This instruction is unpredicated.

SVE

FRSQRTE <Zd>.<T>, <Zn>.<T>

if !HaveSVE() then UNDEFINED;
if size == '00' then UNDEFINED;
integer esize = 8 << UInt(size);

Assembler Symbols

<Zd>

Is the name of the destination scalable vector register, encoded in the "Zd" field.

<T> Is the size specifier, encoded in size:
size <T>
00 RESERVED
01 H
10 S
11 D
<Zn>

Is the name of the source scalable vector register, encoded in the "Zn" field.

Operation

CheckSVEEnabled();
integer elements = VL DIV esize;
bits(VL) operand = Z[n];
bits(VL) result;

for e = 0 to elements-1
    bits(esize) element = Elem[operand, e, esize];
    Elem[result, e, esize] = FPRSqrtEstimate(element, FPCR);

Z[d] = result;
