void(* AVFloatDSPContext::vector_fmac_scalar)(float *dst, const float *src, float mul, int len)

Multiply a vector of floats by a scalar float and add to destination vector.

Source and destination vectors must overlap exactly or not at all.

Parameters:
dst result vector constraints: 32-byte aligned
src input vector constraints: 32-byte aligned
mul scalar value
len length of vector constraints: multiple of 16

void(* AVFloatDSPContext::vector_fmul)(float *dst, const float *src0, const float *src1, int len)

Calculate the product of two vectors of floats and store the result in a vector of floats.

Parameters:
dst output vector constraints: 32-byte aligned
src0 first input vector constraints: 32-byte aligned
src1 second input vector constraints: 32-byte aligned
len number of elements in the input constraints: multiple of 16
