Abstract: The present invention relates to the management of a large and fast memory. The memory is logically subdivided into several smaller parts called buffers. A buffer-control memory (11) having as many sections for buffer-control records as buffers exist is employed together with a buffer manager (12). The buffer manager (12) organizes and controls the buffers by keeping the corresponding buffer-control records in linked lists. A request manager (20), as part of the buffer manager (12), does or does not grant the allocation of a buffer. A stack manager (21) controls the free buffers by keeping the buffer-control records in a stack (23.1), and a FIFO manager (22) keeps the buffer-control records of allocated buffers in FIFO linked lists (23.2 - 23.n). The stack and FIFO managers (20), (21) are parts of the buffer manager (12), too.

Abstract: Ein auf einem Computer ausgeführtes Verfahren zum Verwalten der Verarbeitung von Ressourcen eines computergestützten Systems, das mindestens einen ersten Prozessor und einen zweiten Prozessor aufweist, wobei jeder der Prozessoren funktionsmäßig mit einem Speicher verbunden ist, der einen von einem Prozessor zu verarbeitenden Datensatz speichert, wobei das Verfahren Folgendes umfasst: Überwachen von Daten auf die der erste Prozessor während des Ausführens zugreift; und, wenn der zweite Prozessor weniger weit von den überwachten Daten entfernt ist als der erste Prozessor, Anweisen, einen Ablauf in dem ersten Prozessor zu unterbrechen und den Ablauf in dem zweiten Prozessor wieder aufzunehmen.

Abstract: The invention proposes a switching arrangement for transporting data packets which comprise a data packet destination information and a payload, to one or more output ports. The switching device is able to route the arriving data packets according to the data packet destination information, to at least one dedicated of the output ports. It comprises at each input port an input buffer with at least as many single input queues as there are output ports, and an input controller for each input port, serving for controlling the order of multiplexing the data packets from the input queues of the corresponding input buffer to the switching device. The total of input ports is divided up into several subsets of input ports. Each subset in the switching device has its separate output buffer for storing at addresses therein at least the payload of each data packet arriving at the input port. At least one set of as many output queues as the switching arrangement has output ports are arranged. In these output queues at least the address of each payload stored in the output buffer is stored, sorted according to the data packet destination information. The stored payload is then deliverable to its dedicated at least one output port under use of the stored addresses.

Abstract: A set of interlocking modules supports and connects a die containing lasers, a set of precision molded lenses and a set of beam switching elements. Another embodiment of the invention is a structure for mounting a logic chip and an optical chip on a chip carrier, with the optical chip being mounted on the side of the carrier facing the system board on which the carrier is mounted, so that radiation travels in a straight path from optical sources on the optical chip into optical transmission guides on the board.

Abstract: A switching device comprising several input ports and several output ports, whereby each of the input ports is connectable to a corresponding switch adapter. At least one switch controller controls the routing of incoming data packets from the input ports to the output ports. For each output port a congestion controller is arranged which in operation, generates grant information which signals whether the switch adapters are allowed to send the data packet to the output port. For each of the input ports a data packet access controller marks a data packet as non-compliant if the packet was erroneously sent from said output port.
