Abstract: A data processing system having one or more processor modules and a plurality of shared memory busses to increase its total system performance. Processor modules send bus requests to a bus arbiter, when they attempt to make access to shared memories or memory-mapped peripheral control modules. When such memory access requests are received, the bus arbiter checks the availability of each bus that will be used to reach the requested memories, and send bus grant signals to the requesting processor modules after resolving conflicts, if any. Since the system provides separate paths to reach the individual shared memories, two or more processor modules can be granted their access requests at the same time.

Abstract: A network termination device which will operate correctly even if its connection to a central office has reverse polarity. A network termination device at customer premises is connected to a line termination device located at a central office via a two-wire subscriber loop. If this connection was made with reverse polarity, the supply voltage provided by the line termination device would oscillate at specific intervals, alternating between normal polarity and reverse polarity. In such a case, a polarity switch controller in the network termination device directs its local polarity reversing switch to alternate the polarity at predetermined intervals longer than the cycle time of the above oscillation. This produces such a situation where a reverse supply voltage is present and the polarity reversing switch is in reverse mode, resulting in correct polarity as a whole.

At this time, a sequence specification control section specifies one or more quality classes in sequence. A readout control section reads one or more short cells out from the FIFO memory in accordance with the specified ATM virtual connection and quality class, stores them in one ATM cell and sends the ATM cell to the ATM virtual connection specified by the VC specification control section.
