Latest Patents

One of McEnerney's latest patents is titled "System and method for generating state machines." This invention generates state machines that can be utilized in scanners and parsers for software program compilation. Unlike traditional table-driven state machines, McEnerney's approach encodes state machines directly by creating jumps and branches in bytecodes. This method results in state machines that are not only faster but also smaller in code size compared to those implemented in executable codes. Additionally, these state machines can be optimized to meet strict code size restrictions specified by certain virtual machines, such as the Java virtual machine.

Another notable patent is "System and method for generating multi-way branches." This invention also employs state machines in scanners and parsers for program compilation. The state machines are encoded directly in bytecodes, and a special algorithm is used to generate multi-way branches associated with states in a state machine. This algorithm ensures that the bytecodes are compact and run faster than unoptimized versions. The process involves constructing subarrays, determining optimal branch implementations for each subarray, and ultimately achieving an optimal implementation for the entire target array.
