摘要： An apparatus comprises a given multimode optical waveguide extending in a given direction. The apparatus also comprises another multimode optical waveguide extending in another direction and intersecting with the given multimode waveguide. The apparatus further comprises a bi-stable optical switch positioned at the intersection of the given multimode optical waveguide and the another multimode optical waveguide to redirect a multimode optical signal transmitted on the given multimode optical waveguide to the another optical waveguide in a redirection state and pass the multimode optical signal transmitted on the given multimode optical waveguide across the intersection of the given multimode optical waveguide and the another optical waveguide in a pass-through state. The bi-stable optical switch can comprise a gap extending diagonally from a given corner of the intersection of the given and the another optical multimode waveguides to an opposing corner of the intersection.

摘要： Described is a switch architecture that combines address management with simplified hardware to implement fast route lookup within network switches such as Ethernet switches. A managed address includes a cluster ID which is shared by all endpoints in a cluster, and a member ID which is unique for each node in the cluster. The switch extracts the cluster ID from a target address for a packet and compares it against at least one cluster ID stored in a cluster identification memory. Responsive to a match, the switch generates a port identification for the packet using a fast lookup table. Responsive to no match, the target address is considered an unmanaged address. In one implementation, a slow lookup table can be used to generate a port identification for the unmanaged address.

摘要： A branch operation is processed using a branch predict instruction and an associated branch instruction. The branch predict instruction indicates a predicted direction, a target address, and an instruction address for the associated branch instruction. When the branch predict instruction is detected, the target address is stored at an entry indicated by the associated branch instruction address and a prefetch request is triggered to the target address. The branch predict instruction may also include hint information for managing the storage and use of the branch prediction information.
