Abstract: In various embodiments of the present invention, debugging and program-behavior-analysis software can reconstruct register-based processor states for nested routine calls from the backing-store memory employed by a modern processor, and by processors of similar architectures, to automatically spill and restore register values via a register stack engine. Sufficient information resides in the backing-store memory to reconstruct the stack frames for all nested routines. However, reconstructing the stack frames from the backing-store memory depends on identifying stored register vales in the backing-store memory containing saved values of the previous-frame-marker application register. Various embodiments of the present invention employ a set of heuristic tests to evaluate stored values in the backing-store memory in order to identify those values corresponding to the stored contents of the previous-frame-marker application register.

Abstract: A method of restoring processes within a process domain begins with a step of restoring a tree of processes in which at least two of the processes share at least a resource. The method continues with a step of restoring a checkpoint state of each resource used by the processes after a time when a possible need for a restoration state of the resource exists. According to an embodiment, the restoration state comprises information used by the method during the step of restoring the tree of processes. According to another embodiment, the restoration state comprises information used by the method during the step of restoring the checkpoint state of one or more particular resources. The method concludes with a step of resuming execution of each process after restoration of the checkpoint state of the resources used by the process.

Abstract: The invention includes an apparatus and method of selecting memory cells within a memory array. The method includes receiving a memory cell address. A column address and a row address are generated from the memory cell address. Row select lines or column select lines are pre-charged. A self-timed charging circuit is initiated to provide an adequate amount of time to charge a selected row, and to initiate elimination of static current flowing to unselected rows after a self-timed delay. The other of the row select lines or the column select lines are then pre-charged. Memory cells are selected based upon the column address and the row address. One of two states of the memory cells can be based upon sensing threshold voltages of sense lines that correspond with the selected memory cells.

Abstract: A system for performing an input processing function on a data packet. The system has an input port to which a first processor is coupled, which determines an attribute of the data packet, and a memory coupled to the first processor having a number of queues. The data packet is assigned to one of the queues based upon the attribute determined, which may be an indicator of a priority characterizing said data packet. Input processing is thus performed in a fixed amount of time, deferring variable latency operations until after the input memory.

Abstract: The present invention is a system and method for forwarding packets in order. A first packet may be received for forwarding. Subsequently, a second packet may be received for forwarding. A first memory request corresponding to the first packet is sent. A second memory request corresponding to the second packet may be sent prior to receiving a first memory reply corresponding to the first memory request. The first packet is forwarded prior to forwarding the second packet. In this novel manner, bandwidth in a network apparatus may be utilized with greater efficiency while maintaining packet ordering.

Abstract: A method and apparatus for data security for a distributed file system. A distributed file system interface is coupled to the one or more client applications, and a storage server and a meta-data server are coupled to the distributed file system interface. The meta-data server receives open-file requests from the distributed file system interface and in response creates a security object. The meta-data server also generates an partial encryption key and stores the partial encryption key in the security object. The block storage server completes the encryption key, and the meta-data server encrypts the list of blocks that are in the file and stores the encrypted block list in the security object. The security object is then returned to the distributed file interface and used in subsequent file access requests.

An assessment tool is downloaded or otherwise installed on an end-user client machine and associated with its media player. An assessment server is in communication with the assessment tool over the network and can send control messages to conduct tests and gather information from the assessment tool. The client machine media player is controlled to stop and start by the assessment tool and it will provide measurements that can be forwarded to the assessment servers. Analyses are then produced by the assessment servers of the actual media streams that were received by many such client machine media players. The report servers issue various formatted reports for the system's sponsors and subscribers.

Abstract: A method and apparatus for unique and secure identification of a computing service node. The service node is coupled to an administrative node and to a certificate authority node via a computer network. The administrative and certificate authority nodes have respective public and private keys. A shared key is established between the certificate authority node and the administrative node, and while booting the service node, the service node generates its public key and private key. The administrative node double encrypts a selected value, first using the shared key and second using the public key of the service node, whereby a double encrypted value is generated. The double encrypted value is decrypted at the service node, whereby a single encrypted value is generated. Whether the certificate authority node is able to successfully decrypt the single encrypted value using the shared key determines whether the administrative node is authentic.

Abstract: Embodiments of the present invention provide full benefit of the cover instruction provided by the Intel IA-64 architecture to code running at less than highest privilege level. In one embodiment of the present invention, prior to execution of a cover instruction by non-privileged code, the code obtains and stores the contents of the current-frame-marker register in memory. Then, the code executes a cover instruction to obtain a new, empty register stack frame and to relegate the registers of previously allocated stack frames to the dirty-register status. Subsequently, the processor state represented by the register values of the stack frame that was current when the cover instruction was executed can be recovered by first executing another cover instruction, computing a previous-frame-marker-register value and placing the computed value into the previous-frame-marker register, executing a first branch (br.
