Abstract
A network switching hub is implemented on an IC chip, and has a bus connected to external ports through sets of queue switch transistors, source to drain for data switched onto the bus, the queue switch transistors gated simultaneously by control lines from an on-board arbitrator controller following a preprogrammed arbitration scheme. Data is switched off the bus and hub by port adapter controllers connected to read amplifier receivers connected directly to the on-chip bus, the port adapter controllers enabled by the arbitrator controller following the same preprogrammed arbitration scheme. Ports may be serial or parallel, and may be adapted to special purposes, such as PCI and hub to hub connection for expansion.
Claims11
An integrated circuit switching hub, comprising:
- a plurality of input/output ports;
- a bus communicatively connected to each of said plurality of input/output ports;
- a plurality of data switches that switch data from said plurality of input/output ports onto said bus;
- and
- an arbitrator connected to each of said plurality of data switches that controls said data switches to switch data from any one of said input/output ports to any other of the input/output ports in accordance with a predetermined selection scheme.
An integrated circuit switching hub, comprising:
- a plurality of input/output ports, each of said plurality of input/output ports comprising a media adapter controller that attaches to data layers of a protocol being transmitted and a data buffer;
- a bus communicatively connected to each of said plurality of input/output ports;
- a plurality of data switches that switch data from said plurality of input/output ports onto said bus;
- and
- an arbitrator connected to each of said plurality of data switches that controls said data switches to switch data from any one of said input/output ports to any other of the input/output ports in accordance with a predetermined selection scheme.
