Neonfloat32x4_tvcvtq_n_f32_u32(uint32x4_t a, const int n)Data type conversion / Conversions
Description
Unsigned fixed-point Convert to Floating-point (vector). This instruction converts each element in a vector from fixed-point to floating-point using the rounding mode that is specified by the FPCR, and writes the result to the SIMD&FP destination register.
Results
Vd.4S result
This intrinsic compiles to the following instructions:

UCVTF Vd.4S,Vn.4S,#n

Argument Preparation
a register: Vn.4Sn minimum: 1; maximum: 32
Architectures
v7, A32, A64

Operation

CheckFPAdvSIMDEnabled64();
bits(datasize) operand  = V[n];

bits(esize) element;
FPCRType fpcr    = FPCR[];
boolean merge    = elements == 1 && IsMerging(fpcr);
bits(128) result = if merge then V[d] else Zeros();

for e = 0 to elements-1
    element = Elem[operand, e, esize];
    Elem[result, e, esize] = FixedToFP(element, fracbits, unsigned, fpcr, rounding);

V[d] = result;
