A dynamically reconfigurable token-based optical backplane

We present a 2D token-based dynamically reconfigurable smart pixel array (DRSPA) for intelligent optical backplanes. The DRSPA has the ability to reconfigure both the location and the size of the backplane optical communication channels (between 8, 16, 24, and 32 bits), dynamically enhancing the backplane throughput under light backplane load. This functionality is realized through the use of a 2D token, a 4 clock cycle backplane header, and a distributed control environment.
