Method and apparatus for integrating a computer application programming language runtime environment with an operating system kernel
View Patent ↗An application programming language runtime environment is integrated with an operating system kernel. The resulting merged data structures, meta-data structures and access methods contain the consolidation of information needed by the application programming language runtime and the operating system, without duplication. Integrating resources of the application programming language runtime and the operating system reduces the overall memory needed to store the merges data structures and meta data structures. Additionally, overhead in maintaining multiple data structures in parallel is also reduced, thus reducing the processing required. The integrated application programming language runtime and operating system kernel environment can also sharing semantic behavior such that untrusted application program code is prevented from escaping the application programming language runtime environment.
