A ring-based crossbar data switch, a method and a computer program are provided for the transfer of data between multiple bus units in a memory system. Each bus unit is connected to a corresponding data ramp. Each data ramp is only directly connected to the adjacent data ramps. This forms at least one data ring that enables the transfer of data from each bus unit to any other bus unit in the memory system. A central arbiter manages the transfer of data between the data ramps and the transfer of data between the data ramp and its corresponding bus unit. A preferred embodiment contains four data rings, wherein two data rings transfer data clockwise and two data rings transfer data counter-clockwise.

A computer architecture and programming model for high speed processing over broadband networks are provided. The architecture employs a consistent modular structure, a common computing module and uniform software cells. The common computing module includes a control processor, a plurality of processing units, a plurality of local memories from which the processing units process programs, a direct memory access controller and a shared main memory. A synchronized system and method for the coordinated reading and writing of data to and from the shared main memory by the processing units also are provided. A hardware sandbox structure is provided for security against the corruption of data among the programs being processed by the processing units. The uniform software cells contain both data and applications and are structured for processing by any of the processors of the network. Each software cell is uniquely identified on the network. A system and method for creating a dedicated pipeline for processing streaming data also are provided.

To effectively restrain a rider on a seat provided at a rear portion of a vehicle body with an inflated air bag in a scooter type vehicle having a footrest for supporting the feet of the rider. An air bag that can be inflated so as to restrain a rider on a seat from the front side of the rider is accommodated in a folded condition inside a front end portion of the seat.
摘要:
A firewall (FW) which detects a DOS attack cuts off the DOS attack, and outputs a log indicating an attack, and designates a source IP address of the DOS attack. A filtering command for cutting off an attack is generated in a router, and transmits it to the router. The router discards a packet transmitted from the specified IP address through the filtering operation.
摘要:
A system configuration includes a processing element (PE), an input/output (I/O) interface device and a shared memory. The PE further includes at least one processing unit (PU) and one, or more, attached processing units (APUs). At least one of the APUs performs an I/O function by reading data from, and writing data to, an external device coupled to the I/O interface device. Data is exchanged between the APU and the I/O interface device via the shared memory using a data level synchronization mechanism.
