    摘要： A system for storing a distributed hash table. The system includes a storage unit, a tablet controller, a router, and a transaction bank. The storage unit has a plurality of tablets forming a hash table and each of the tablets includes multiple records. The tablet controller maintains a relationship between each tablet and the storage unit. The router hashes a record's key to determine the tablet associated with each record. Further, the router distributes messages from clients to the storage units based on the tablet-storage unit relationship thereby serving as a layer of indirection. The transaction bank propagates updates made in one record to all other replicas of the record.

    摘要： A system and method are described for providing intelligence to an analysis probe being utilized by logic analyzers. The system provides for regenerating target system internal processor data signals for analysis by a logic analyzer from data lines that are being utilized for other purposes by the target system processor. In particular, the analysis probe includes programmable logic for providing an interface between an emulation module and the target system, a memory for receiving signal reconstruction data from the emulation module, a processor for generating a data map from signal reconstruction data, and programmable logic for generating a target system internal signal from at least one of a plurality of target system data signals and the signal reconstruction data.

    摘要： A system for maintaining a database. The system includes a storage unit for storing many tablets each tablet including multiple records. The tablet controller is configured to maintain the relationship between the tablet and the storage unit. The tablet controller tracks failures to access the storage unit and designates a new storage unit for each tablet based on a storage unit failure. A router is in communication with the tablet controller and configured to distribute messages from clients to the storage units thereby serving as a layer of indirection.

    摘要： A system for a distributed database implementing a dynamic mastership strategy. The system includes a multiple data centers, each having a storage unit to store a set of records. Each data center stores its own replica of the set of records and each record includes a field that indicates which data center is assigned to be the master for that record. Since each of the data centers can he geographically distributed, one record may be more efficiently edited with the master being one geographic region while another record, possibly belonging to a different user, may be more efficiently edited with the master being located in another geographic region.
