Abstract: Interrupt controller comprises parallel input (30) for receipt of a first interrupt request signal, means (31) for output of a second interrupt request signal as a reaction to the first interrupt request signal, state processing means (32) for determining interrupt priority, memory (37) for storing addresses of interrupt servicing programs whereby each servicing program handles an interrupt signal and means (36) for selection of an address based on the priority.

Abstract: A system for data compression has a multi-stage pipeline structure 113 and a distributed memory comprising a main hash table 101 and at least one victim hash table 103. The system concurrently writes an uncompressed data element 105 in the main hash table using a first address 115 generated by a first hash function 107 on the data element, and reads a first data element 109 from the main hash table using the first address, so as to avoid a collision. The system then concurrently writes the first data element to the victim hash table using a second address 117 generated by a second hash function 111 on the first data element, and reads a second data 120 element from the victim hash table using a third address 121generated by the second hash function on the uncompressed data element. The first or second data element is selected depending on which has the longest match to the uncompressed data element, and is used for providing a compressed format with backward reference to the longest match.

Abstract: A packet pre-processing unit receives a data packet containing header information and application data, checks the validity of the packet by reference to stored subscription data using header data for the IP destination address, destination port and VLAN tag, checks whether the application data has already been received, and only outputs the packet for further processing if the packet is valid and doesnt contain redundant application data, thereby reducing the load of the memory, bus, and CPU of the computer system.

Abstract: The processor has a processing unit (1) and an automobile interface unit (2) provided by separate structural components, with a further separate structural component provided by a communications coprocessor (3) for linking the processing unit to a number of peripheral devices. The communications coprocessor is provided with a bandwidth adaptor and a gateway-processor as structural components.
