  • Patent number: 7650464
    Abstract: Data locality optimization through object relocation may be implemented in a virtual machine including a just-in-time compiler. The just-in-time compiler generates load instruction maps for each compiled method. A profile collector is coupled to the just-in-time compiler to receive hardware profiling support. The profile collector takes samples of data cache misses. A garbage collector is coupled to the profile collector. The garbage collector deduces types of objects from the cache miss samples and adjusts garbage collection object copying heuristics to relocate objects for better cache locality based on those types.

  • Patent number: 7424705
    Abstract: Disclosed are a method, apparatus and system for dynamically managing layout of compiled code in a managed runtime environment. Profile feedback is generated during runtime, based on hardware event data that is gathered during runtime. A code manager dynamically relocates compiled code to reduce miss events based on the profile feedback. The code manager may also relocate virtual method tables in a virtual table region in order to reduce data miss events. The method does not require a prior run of an application program because profile feedback is based on event data that is tracked by hardware during execution of the software application and is not based on instrumented code.
