WebLoop pipelining is a performance optimization in high-level synthesis (HLS), which extracts loop-level parallelism by executing multiple loop iterations concurrently using the same hardware. The key performance metric when loop pipelining is the time interval between starting successive loop iterations, called the initiation interval (II).

Therefore, I set the pragma array partition on the array "mp_buffer" and "mc_buffer" under the declaration of them (which is outside of "find_match"), and I set them into find_match as arguments. However, there is an II violation because the array is not patitioned.
