API starts with the prefix aocl_gemm_ and follows the data type id
of input matrix A, B, accumulation type, and output matrix C.
For example, aocl_gemm_u8s8s32os32( ) API expects input matrix ‘A’
is unsigned 8-bit integer (u8) and matrix ‘B’ signed 8-bit integer (s8),
accumulation matrix is signed 32-bit integer (s32) and output matrix ‘C’
type is signed 32-bit integer (o s32).
