Patent ID: 6967950

Claim:
A data routing unit comprising: a data receiver; a data transmitter; a bridge circuit connected to supply data to said data receiver and to receive data from said data transmitter, said bridge circuit connected to at least one set of data input lines and at least one set of data output lines, said bridge circuit responsive to a header of a data packet received from said data transmitter or received from said at least one set of data input lines to selectively route said received data packet to (1) said data receiver, (2) a selected set of said at least one set of data output lines, or (3) both said data receiver and a selected set of said at least one set of data output lines dependent upon said header; an input/output memory connected to said data receiver for storing data received by said data receiver and to said data transmitter for storing data to be transmitted by said data transmitter, said input/output memory further storing transmitter scripts for controlling data transmission by said data transmitter; said data receiver generating an interrupt to said data transmitter to transmit predetermined response data upon detection of a predetermined receiver event signaled in said data packet; and said data transmitter executing a transmitter script stored at a predetermined location within said input/output memory upon interruption by said data receiver.
