摘要： In typical Java and other interpreted programming language environments, the code is stored in ROM in a semi-processed state, .class files containing byte codes. When the device is turned on, a virtual machine resolves references and links the .class file in RAM to permit desired applications to be run. In the invention, the .class files are further pre-processed to select the data which will not change or require updating. This data is packaged into memory image files containing internal data pre-linking this data. The memory image files are stored in ROM and are accessible from ROM by the virtual machine at runtime. Only elements that will be updated, such as the objects themselves, must be instantiated in RAM at runtime. This reduces the amount of RAM needed to run the application. In an environment with memory constraints, the reduction in RAM requirements permits more RAM to be made available for application use.
摘要翻译： 在典型的Java和其他解释型编程语言环境中，代码以半处理状态存储在ROM中，包含字节代码的.class文件。 当设备打开时，虚拟机将解析引用并将RAM中的.class文件链接以允许运行所需的应用程序。 在本发明中，进一步对.class文件进行预处理，以选择不改变或需要更新的数据。 该数据被打包到包含预先链接该数据的内部数据的存储器图像文件中。 存储器映像文件存储在ROM中，并且可以在运行时由虚拟机从ROM访问。 只有要更新的元素（如对象本身）必须在运行时在RAM中实例化。 这减少了运行应用程序所需的RAM量。 在具有内存限制的环境中，RAM要求的减少允许更多的RAM可用于应用程序的使用。

摘要： The stack mapper of the present invention seeks to determine the shape of the stack at a given program counter. This is accomplished by locating all start points possible for a given method, that is, at all of the entry points for the method and all of the exception entry points, and trying to find a path from the beginning of the method to the program counter in question. The mapper first tries to locate a linear path from the beginning of the method, and then iteratively processes the sequence of bytes at each branch until the destination program counter is reached. Once the path is found, a simulation is run of the stack through that path, which is used as the virtual stack for the purposes of the garbage collector.

摘要： Under the present invention, program code is examined (statically or dynamically) for characteristics indicative of a potential to generate multiple threads. If none are found, single threaded optimization(s) such as desynchronization, optimization of globals, etc., can be implemented. In addition, if the program code is later revealed to have the potential to generate multiple threads, the single threaded optimization(s) can be corrected to avoid incorrect execution.
摘要翻译： 在本发明的范围内，针对指示产生多个线程的潜力的特性，检查（静态地或动态地）程序代码。 如果没有找到，则可以实现单线程优化，例如去同步，全局变量优化等。 另外，如果稍后显示程序代码有可能生成多个线程，则可以纠正单线程优化以避免错误执行。

摘要： A method, apparatus, and computer instructions for referencing a constant pool. A determination is made as to whether a bytecode references the constant pool. A relative offset to the constant pool is identified for the bytecode, in response to the bytecode referencing the constant pool. The bytecode is then replaced with a new bytecode containing the relative offset. The relative offset is used to reference the constant pool.

摘要： Memory segments are allocated for a classloader to store class information, such as by selecting an allocation approach based on classloader type. In a first approach, in response to each request, a segment having a fixed size is allocated. In a second approach, in response to a first request, a first segment having a size equal to an amount of memory needed to store information related to the request is allocated. In response to a second request, a second segment having a second size is allocated, and in response to a third request, a third segment having a third size greater than the second size is allocated. In a third approach, in response to the first request, a first segment having a first size is allocated. In response to a second request, a second segment having a second size greater than the first size is allocated.

摘要： Virtual function calls in hybrid compiled and interpreted computer programming environments are carried out efficiently by dual virtual function tables. Each class object generated is provided with a compiled virtual function table and an interpreted virtual function table. Each table is symmetrically structured and contiguous with the class object. Calls from an interpreted function access the interpreted virtual function table. Entries in that table point to function data structures which provide for the interpretation of the called function, or for transfer to execution of a compiled version of the called function. Calls from a compiled function access the compiled virtual function table. Entries in the compiled virtual function table point to either executable code representing the called function, or to transition code for transition to the interpreter to interpret the called function.
