    Abstract: A data processing system is provided which includes a processor nest communicatively coupled to an input/output bus by a bus controller, and a service interface controller communicatively coupled to the processor nest. The system includes storage for storing commands for the bus controller and associated command data and resulting status data, the storage being communicatively coupled to the processor nest and the bus controller. The service interface controller is configured, in response to received service commands, to read and write the storage, to execute the command specified in the storage, to retrieve the result of the command, and to store the result in the storage.

    Abstract: Creating hash values based on bit values of an input vector. An apparatus includes a first and a second hash table, a first and second hash function generator adapted to configure a respective hash function for a creation of a first and second hash value based on the bit values of the input vector. The hash values are stored in the respective hash tables. An evaluation unit includes a comparison unit to compare a respective effectiveness of the first hash function and the second hash function, and an exchanging unit responsive to the comparison unit adapted to replace the first hash function by the second hash function.

    Abstract: A data processing apparatus includes a number of processor cores, a shared processor cache, a bus unit and a bus controller. The shared processor cache is connected to each of the processor cores and to a main memory. The bus unit is connected to the shared processor cache by a bus controller for transferring data to/from an I/O device. In order to achieve further improvements to the data transfer rate between the processor cache and I/O devices, the bus controller is configured, in response to receiving a descriptor from a processor core, to perform a direct memory access to the shared processor cache for transferring data according to the descriptor from the shared processor cache to the I/O device via the bus unit.
