Latest Patents

One of his latest patents is titled "Method for unwinding a program call stack." This method instructs a computing system to unwind a program call stack that lacks explicit Stack Frame Backchain Pointers. It includes steps for finding the called function's entry point, determining the return point in the calling function, and placing a NOP instruction at the return point that contains embedded information about the type of call used. Additionally, it involves backing up in storage by an amount determined using the address of the called function's entry point to locate the static data item containing the called function's DSA size.

Another significant patent is "Compile-time data dependency verification." This invention is a compiler extension for the compile-time verification of programmer-defined data dependencies. It provides a check statement that takes a data-verification expression as an argument. The expression has a predetermined value when the programmer-defined data dependency is conformed to in the program. If the data-verification expression does not have the predetermined value during compilation, a compile-time error is generated. The successful compilation of the check statement does not result in run-time code or data allocation.
