Detailed Description

Function Documentation

◆ DSPF_sp_mat_mul_gemm()

void DSPF_sp_mat_mul_gemm ( float *  x1,
float const  a,
const int  r1,
const int  c1,
float *  x2,
const int  c2,
float *restrict  y 
)
 This function computes the expression y = a*x1*x2+y. The column 
 dimension of x1 must match the row dimension of x2.
 The values stored in the matrices are assumed to be single-precision 
 floating-point values. This code is suitable for 
 dense matrices. No optimizations are made for sparse matrices.

@param  x1  = Pointer to r1 by c1 input matrix.
@param  a   = Scalar value.
@param  r1  = Number of rows in x1.
@param  c1  = Number of columns in x1. Also number of rows in x2.
@param  x2  = Pointer to c1 by c2 input matrix.
@param  c2  = Number of columns in x2.
@param  y   = Pointer to r1 by c2 output matrix.
Algorithm:
DSPF_sp_mat_mul_gemm.c is the natural C equivalent of the optimized intrinsic C code withoutrestrictions. Note that the intrinsic C code is optimized and restrictions may apply.
Assumptions:
The arrays x1, x2 and y are stored in distinct arrays. In-place processing is not allowed.
r1, c2 are assumed to be an integer multiple of 4. c1 is assumed to be even.
Implementation Notes:
Interruptibility : The code is interruptible.
Endian support : supports Little endian mode.
