Abstract
A packetized data bus interface may be placed in a mode where data packets may be transmitted that are much larger than the standard packet size. The mode may allow the interface device and any other devices, networks, or transmission lines attached to the interface device to be more thoroughly exercised than previously able. The mode may be used for characterizing various aspects of the data interface.
Claims6
A data interface comprising:
- a data input;
- an override signal input;
- an output being connected to a data bus, said data bus being a packetized data bus for the communication of data in packetized form having a maximum packet size;
- and
- a processor capable of receiving a large data block on said data input, said large data block being larger than said maximum packet size, creating a large packet of data that is larger than said maximum packet size when said override signal input is actuated, and transmitting said large packet over said output, said processor further capable of receiving said large data block on said data input, creating a plurality of small packets of data that are the same size or smaller than said maximum packet size when said override signal input is not actuated, and transmitting said small packets over said output.

A method of transmitting data on a packetized data interface comprising:
- providing a data input;
- providing an override signal input;
- providing a packetized data bus for the communication of data in packetized form having a maximum packet size;
- providing an output connected to said data bus;
- receiving a first large data block on said data input, said first large data block being larger than said maximum packet size;
- creating a first large packet of data that is larger than said maximum packet size when said override signal input is actuated;
- transmitting said large packet over said output;
- receiving a second large data block on said data input, said second large data block being larger than said maximum packet size;
- creating a plurality of small packets of data that are the same size or smaller than said maximum packet size when said override signal input is not actuated;
- and
- transmitting said small packets over said output.
