  • Caching run-time variables in optimized code
    Patent number: 8479183
    Abstract: In one embodiment, the present invention includes a method for emitting a live range statement into a program for a memory variable to be cached during run-time that has at least one simulation state variable if the memory variable is dynamically mapped, and defining the simulation state variable at a first execution path of the program. In such manner, the program may be optimized using the live range statement and the simulation state variable. Also, a debugger may use the simulation state variables in obtaining and displaying the memory variable from a cache.
    Type: Grant

  • Method of replacing initialization code in a control store with main code after execution of the initialization code has completed
    Patent number: 7249252
    Abstract: A method includes loading initialization code into a control store in an embedded microprocessor and executing the initialization code. The method determines if the execution of the initialization code is complete and replaces the initialization code in the control store with main code.
