Abstract: A method of manufacturing a carrying substrate is provided. At least one circuit component is disposed on a first circuit structure. An encapsulation layer is formed on the first circuit structure and encapsulates the circuit component. A second circuit structure is formed on the encapsulation layer and electrically connected to the circuit component. The circuit component is embedded in the encapsulation layer via an existing packaging process. Therefore, the routing area is increased, and a package substrate requiring a large size has a high yield and low manufacturing cost.

Abstract: The present invention provides techniques for controlling the functionality of a network processor and for facilitating integration of the network processor with a host system. Application programming interfaces (APIs) are provided which can be invoked by the host system for performing device level functions on the network processor. The APIs are provided by a device control module which may execute either on the host system or on the network processor. A host application may invoke an API and the function corresponding to the invoked API is performed by the network processor. Responses or results from the function execution may then be forwarded by the network processor to the host application.

Abstract: System and method in a network processor for performing cut-through forwarding of LANE packets without incurring the overhead associated with LANE protocol stack assisted routing. A content addressable memory (CAM) stores LEC uplink information including mapping between MAC destination addresses and VCC information. The network processor also stores LEC information table for corresponding VLAN identifiers and LECs. The LEC information table includes LEC ID information for the VLAN ID. For a LANE packet received from Ethernet and outbound to ATM destination, the network processor determines the LEC ID for the packet and then performs a CAM lookup to determine VCC information for the packet. The packet is then forwarded using the LEC ID and VCC information. For a LANE packet received from an ATM source and outbound to the Ethernet, the network processor determines the interface address of the packet.

Abstract: The present invention provides application programming interfaces (APIs) which allow a host to control the functioning of a network processor and also perform various network data manipulation functions. The APIs are intended to encapsulate as much as possible the underlying messaging between the host system and the network processor and to hide the low device level command details from the host. The APIs are provided by a program module. A host may invoke an API which is then communicated by the program module to the network processor where functions corresponding to the API are performed. Responses to the APIs may be forwarded back to the host. Asynchronous callback functions, invoked in response to the API calls, may be used to forward responses to the host.
