A.1.1.2.3 Ownership Trace<br />
Ownership is a NEXUS term; it translates to .Task ID. or .Process ID. for most practical<br />
purposes. The generic OTU is able to process the ownership information of an arbitrary<br />
processor core if implemented in hardware.<br />
As the rate of change for the process ID is rather low, it will be sent multiplexed over other<br />
trace interface signal lines of the core quite often. This is perfectly legal, provided a dedicated<br />
signal to drive the mode port is available. If the core is not doing any useful work (e.g. if no<br />
task is active), the process ID should be invalidated by FORGET.<br />
