Overview

Converts the samples in the inputVector from 32-bit integers into floating point values and then divides them by the input scalar.

Dispatcher Prototype

void volk_32i_s32f_convert_32f(float* outputVector, const int32_t* inputVector, const
float scalar, unsigned int num_points) 

Inputs

• inputVector: The vector of 32-bit integers.
• scalar: The value that the output is divided by after being converted to a float.
• num_points: The number of values.

Outputs

• complexVector: The output vector of floats.

Example Convert full-range integers to floats in range [0,1].

int N = 1<<8;
unsigned int alignment = volk_get_alignment();
 
int32_t* x = (int32_t*)volk_malloc(N*sizeof(int32_t), alignment);
float* z = (float*)volk_malloc(N*sizeof(float), alignment);
float scale = (float)N;
for(unsigned int ii=0; ii<N; ++ii){
    x[ii] = ii;
}
 
volk_32i_s32f_convert_32f(z, x, scale, N);
 
volk_free(x);
volk_free(z);
