Abstract
A data processing system includes a plurality of processing units coupled for communication by a communication link and a configuration register. The configuration register has a plurality of different settings each corresponding to a respective one of a plurality of different link information allocations. Information is communicated over the communication link in accordance with a particular link information allocation among the plurality of link information allocations determined by a respective setting of the configuration register.
Claims18
A data processing system, comprising:
- a plurality of processing units coupled for communication by a communication link;
- a configuration register having a plurality of different settings each corresponding to a respective one of a plurality of different link information allocations, wherein information is communicated over said communication link in accordance with a particular link information allocation among said plurality of link information allocations determined by a respective setting of said configuration register.
A processing unit, comprising:
- a processor core;
- interconnect logic coupled to a communication link coupling the processing unit to another processing unit for communication;
- and
- a configuration register having a plurality of different settings each corresponding to a respective one of a plurality of different link information allocations, wherein information is communicated over said communication link in accordance with a particular link information allocation among said plurality of link information allocations determined by a respective setting of said configuration register.
A method of data processing, comprising:
- in a configuration register having a plurality of different settings each corresponding to a respective one of a plurality of different link information allocations for a communication link coupling processing units of a data processing system, setting said configuration register to a particular setting among said plurality of settings;
- and
- communicating information over said communication link in accordance with a selected link information allocation among said plurality of link information allocations determined by said particular setting of said configuration register.
