An N-port memory architecture is disclosed that stores multi-dimensional arrays so that: N contiguous elements in a row can be accessed without blocking, N contiguous elements in a column can be accessed without blocking, some N-element two-dimensional sub-arrays can be accessed without blocking, and all N2-element two-dimensional sub-arrays can be accessed without blocking. It includes a cylindrical inner conductor and a cylindrical cladding tube connection region which is arranged concentrically with respect to the inner conductor. During the same symbol period, one of the possible values is selected as the next-cycle input sample based on at least one of the next-cycle path memory symbols produced from the symbol decoder. The airflow opening directs air under the vehicle therethrough in order to create a down force on the vehicle.
