Latest Patents

One of his latest patents is titled "Method and apparatus for identifying remediation failures in year-2000 remediation programs." This invention utilizes object-code instruction traces to analyze specific instructions of a year-2000 remediated application program for potential failures when faced with a year-2000 date. The analysis directly identifies instructions that may fail and assigns a remediation-failure-pattern descriptor to each examined instruction, indicating the likelihood of failure. The method employs user-specifiable run-control values and predetermined filter-specification values to compare traces of selected object-code instructions against predefined remediation-failure patterns.

Another significant patent by David E. Lee is "Method and apparatus for performing a trap operation in an information handling system." This invention introduces a Trap instruction within a central processing unit (CPU) to facilitate the transfer of control from a user program to a trap program. The CPU saves state information from the program status word, general registers, and access registers in a designated trap save area. It then loads the address of a trap control block and transfers control to the trap program. Upon completion, the trap program can issue a Resume Program instruction to restore the previously saved state information, allowing the user program to continue execution seamlessly.
