Latest Patents
David R. Schroeder holds a patent for a "System and method for testing interrupt processing logic within an instruction stream." This innovative system allows for the selective injection of interrupts into the instruction stream of a data processing system. The technology includes a programmable storage device that stores interrupt injection signals associated with specific machine instructions. When the execution of these instructions begins, the stored signals are read and can trigger interrupts within the instruction processor. This capability enables the simultaneous injection of various types of interrupts, including fault and non-fault interrupts, during instruction execution. The invention simplifies the testing process by eliminating the need for complex simulation programs, allowing any simulation program to utilize the interrupt injection system for testing purposes. Additionally, the system can be employed during normal operations to provide temporary fixes to hardware issues, all while remaining transparent to the operating system.
