Constraints - 2024.1 English

A Matrix-Multiplication solution can consist of a TP_SSR number of cascaded kernel paths (each containing TP_CASC_LEN kernels). There is also the option to add tiler and detiler kernels to the solution. Tiler kernels can be added for each input port for each kernel, and detiler kernels can be added on the final output of each SSR path.

The tiling kernels’ function is to convert between the arrangement of matrix elements in memory to a form of arrangement optimized for vector multiply, or vice versa. In the entry level graph, the following names are used to identify the various kernels as follows:

• ‘m_MatmultKernels’ - This is the array of kernel pointers returned by getKernels which point to the cascade TP_CASC_LEN of matrix multiply kernels. These kernels perform the matrix multiply operations.
• ‘untiler’ - This is an array of TP_SSR kernels on the output of the each Matrix Multiply SSR path. It performs the transformation from a tiled format to the true output format.
• ‘tilerA’ - This is an array of TP_CASC_LEN * TP_SSR kernels which connect 1:1 with the A input port of the matrix multiply kernels.
• ‘tilerB’ - This is an array of TP_CASC_LEN * TP_SSR kernels which connect 1:1 with the B input port of the matrix multiply kernels.
