Latest Patents

One of Lowney's latest patents is a "Mechanism for executing computer instructions in parallel." This invention includes a compiler that generates and groups instructions into multiple sets for parallel execution. Each set is uniquely identified, allowing a computer system to execute instructions in both real and speculative states. The system generates speculative data while executing instructions, and logic circuits are included to detect any exceptions that may arise during execution. If an exception occurs, the instructions are re-executed to resolve the issue and incorporate the speculative data into the real state of the system.

Another significant patent is the "Mechanism for enforcing the correct order of instruction execution." This apparatus utilizes content addressable memory to store and compare load and store addresses of data. It generates signals to ensure that selected instructions are executed in the correct order, repeating execution if necessary. This innovation enhances the reliability and efficiency of instruction processing in computer systems.
