Multiport memory based data path allocation focusing on interconnection optimization

A method based on the 0-1 integer linear programming (ILP) model aiming primarily at minimizing the cost of interconnections is proposed for solving the data path allocation problem using multiport memories. The interconnection elements are generally composed of buses, multiplexers, and tri-state buffers. After solving the operation binding problem, we first find the number of buses required. Then we deal with the multiport memory allocation problem simultaneously minimizing the cost of multiplexers and tri-state buffers. From the solution quality and execution time of the experimental results, we see that our method is suitable for solving data path allocation problem using multiport memories when the cost of interconnections is first considered
