Summary: | Disclosed is a method and apparatus for program event recording in a data processing system and is used, for example, in debugging programs. A program event occurs whenever an address in the data processing system falls within a range between a control lower address (DTCL) and a control upper address (DTCU). The system detects a program event without degrading system performance using carry-lookahead adder structures which implement four inequality relationships. |
