    Abstract: To reduce FIFO access cycles across a system bus in a multi-processor system in which two processors communicate across a system bus through a FIFO, two separate FIFO descriptors are provided. The first descriptor is maintained by the processor located on-board with the FIFO, and the second descriptor is maintained by an off-board processor which communicates with the FIFO across the bus. When one processor performs a FIFO operation, the processor updates the other processor's descriptor via a memory access across the bus. Additionally, one module passes credits to the other to indicate that the latter has permission to perform a plurality of FIFO operations consecutively. In one embodiment a special non-valid data value is used to indicate an empty FIFO position.

    Abstract: An asynchronous transfer mode (ATM) digital electronic communication system includes an ATM communication system interconnection and termination unit (ATMCSI/TU). This ATMCSI/TU includes both a programmable microprocessor and several hardware-implemented coprocessors. The hardware-implemented coprocessors are under control of the microprocessor, and are dedicated to the performing of repetitive tasks. Thus, the microprocessor is freed to perform supervisory tasks in the ATM in addition to performing tasks associated with actual communication of digital data packages (i.e., CS-PDU's) in the ATM system. Thus, the APU is freed from doing repetitive data manipulation tasks, while these tasks are performed by one or more hardware-implemented coprocessors using memory mapped data structures and linked lists of data.

    Abstract: The invention relates to a process for producing a water-absorbing resin by polymerization of a reaction mixture comprising at least one hydrophilic monomer and, if appropriate, at least one crosslinker in a reactor, which comprises admixing the reaction mixture with at least one first portion of a particulate additive before the reaction mixture has reached a residence time of 40% of the overall residence time in the reactor and with at least one second portion of a particulate additive when the reaction mixture has reached a residence time of 45% or more of the overall residence time in the reactor, the additive being selected from water-absorbing resin powders, fillers and mixtures thereof, the total solids content of monomer and additive being in the range from 30% to 60% by weight, the amount of additive being in the range from 5% to 50% by weight, based on the monomers, and the weight ratio of the first portion to the second portion of the additive being in the range from 10:1 to 1:5. The resin powder is recycled fine-sized material for example. Not only the residual monomer content, specifically the residual crosslinker content, but also the level of extractables in the water-absorbing resin are reduced by the method of addition described. A high fraction of additives can be incorporated without the properties of the water-absorbing resin obtained being adversely affected. The additives enter a sufficiently firm bond with the resin, so that no excessive dusting occurs on exposure to mechanical stress.
