Appeal 2007-1754
Application 09/943,599
STATEMENT OF THE CASE
Appellants invented a system and method for providing data processor
emulation information including providing a trace stream used to monitor
activity such as program flow and memory accesses. In one embodiment,
trace information is provided including identifying a program counter value
that corresponds to a particular data processing operation. The counter value
is expressed as an offset that indicates a number of program counter values
in the program counter trace stream by which the corresponding program
counter value is offset from the synchronization marker in the program
counter trace stream.2 Claim 1 is illustrative with the disputed limitations
italicized for emphasis:
1. A method of providing data processor emulation information,
comprising:
providing a program counter trace stream of program counter values
used by a data processor;
inserting a synchronization marker into the program counter trace
stream; and
providing trace information indicative of each data processing
operation performed by the data processor, including identifying a program
counter value that corresponds to the data processing operation, said
identifying step including expressing said corresponding program counter
value as an offset which indicates a number of program counter values in
the program counter trace stream by which said corresponding program
counter value is offset from said synchronization marker in said program
counter trace stream.
