1. New LPGEMM type - s8s8s16os16 and s8s8s16os8 are added. 2. New interface, frame and kernel files are added. 3. Frame and kernel level files added and modified for s8s8s16 4. s8s8s16 type involves design changes of 2 operations - Pack B and Mat Mul 5. Pack B kernel routines to pack B matrix for s16 FMA and compute the sum of every column of B matrix to implement the s8s8s16 operation using the s16 FMA instructions. 5. Mat Mul Kernel files to compute the GEMM output using s16 FMA. Here the A matrix elements are converted from int8 to uint8 (s16 FMA works with A matrix type uint8 only) by adding extra 128 to every A matrix element 6. Post GEMM computation, additional operations are performed on the accumulated outputs to get the correct results. Final C = C - ( (sum of column of B matrix) * 128 ) This is done to compensate for the addition of extra 128 to every A matrix elements 7. With this change, two new LPGEMM APIs are introduced in LPGEMM - s8s8s16os16 and s8s8s16os8. 8. All previously added post-ops are supported on s8s8os16/os8 also.
