Abstract:
|
|
|
|
This module implements the kernels for the floating point matrix/matrix
|
|
multiply operation (SGEMM and DGEMM).

Routine Description:
|
|
|
|
This routine is an inner kernel to compute matrix multiplication for a
|
|
set of rows.
|
|
|
|
Arguments:
|
|
|
|
A (rdi) - Supplies the address of matrix A.
|
|
|
|
B (rsi) - Supplies the address of matrix B. The matrix data has been packed
|
|
using MlasSgemmCopyPackB or MlasSgemmTransposePackB.
|
|
|
|
C (rdx) - Supplies the address of matrix C.
|
|
|
|
CountK (rcx) - Supplies the number of columns from matrix A and the number
|
|
of rows from matrix B to iterate over.
|
|
|
|
CountM (r8) - Supplies the maximum number of rows that can be processed for
|
|
matrix A and matrix C. The actual number of rows handled for this
|
|
invocation depends on the kernel implementation.
|
|
|
|
CountN (r9) - Supplies the number of columns from matrix B and matrix C to
|
|
iterate over.
|
|
|
|
lda - Supplies the first dimension of matrix A.
|
|
|
|
ldc - Supplies the first dimension of matrix C.
|
|
|
|
Alpha (xmm0) - Supplies the scalar alpha multiplier (see GEMM definition).
|
|
|
|
ZeroMode - Supplies true if the output matrix must be zero initialized,
|
|
else false if the output matrix is accumulated into.
|
|
|
|
Return Value:
|
|
|
|
Returns the number of rows handled.
