Latest Patents

Öhrström's latest patents include a "System and method for removal of array copies in Java by cutting the length of arrays." This invention focuses on reusing a source array for the target array, potentially cutting the length of the source array. The system comprises physical computers or similar computing devices, a computing or virtual execution environment, and a virtual machine that includes a compiler. The compiler performs static analysis of the code to determine if an array copy can be replaced with a reuse of the source array, modifying the generated machine code accordingly.

Another significant patent is the "System and method for efficient compilation and invocation of function type calls." This invention is designed for use in a virtual machine, particularly the Java Virtual Machine (JVM). The system includes a memory space for application bytecode and a bytecode to machine code compiler that performs MethodHandle invocation optimizations. It enables carrying the function type from the original MethodHandle to a callsite in the generated bytecode, maintaining generics information for function types.
