System and methods for connecting multiple functional components

The present invention relates to a flexible and reconfigurable bus fabric for microelectronic processing units, which can offer efficient memory data management, together with efficient data transfer and relieving data transfer congestion in an integrated circuit. In an embodiment, the present reconfigurable bus fabric comprises a multistate intersection between two data buses. Preferably, the multistate intersection comprises at least two states, a connecting state connecting the two data buses, and a disconnecting state disconnecting the two data buses. The multistate intersection provides a reconfigurable bus fabric, allowing different connection configuration for the data buses. This reconfigurable bus fabric offers soft-configurability and soft-reconfigurability, using software programming to arrange the circuits' interconnections. Other configurations are also disclosed in exemplary embodiments.
