Provided are a method, system, and article of manufacture, wherein a plurality of objects are allocated in dynamic memory. Reversed references are determined for the plurality of objects, wherein a reversed reference corresponding to an object is an address of a location that has a valid reference to the object. Unreferenced objects are deleted to fragment the dynamic memory. The fragmented dynamic memory is compacted via adjustments to the reversed references.

A method, apparatus, and system are provided for integrating mark bits and allocation bits. According to one embodiment, a single space is allocated for accommodating a mark bit and an allocation bit. The mark bit and the allocation bit are integrated into a mark/allocation bit using the single space allocated. The mark/allocation bit then used to correspond to an object in a heap.

A virtual machine in a processing system manages type information for operands. In one embodiment, the virtual machine accomplishes the following results through execution of a single instruction: adding an operand tag to a tag stack, and updating a stack pointer for the tag stack to recognize the addition of the operand tag to the tag stack. The single instruction may be a shift instruction, for example. The tag stack may reside in a tag stack register, and each operand tag may indicate whether a corresponding operand on an operand stack is to be treated as a reference operand or a non-reference operand. Other embodiments are described and claimed.

A method and apparatus for reducing the effect of soft errors in a computer system is provided. Soft errors are detected by combining software redundant threading and instruction duplication. Upon detection of a soft error, errors are recovered through the use of software check pointing/rollback technology. Reliable regions are identified by vulnerability profiling and redundant multi-threading is applied to the identified reliable regions.
摘要:
A heap organization for a multitasking virtual machine is described. The heap organization may comprise an execution engine to concurrently execute a plurality of tasks and a plurality of heaps coupled to the execution engine. In some embodiments, the plurality of heaps may comprise a system heap and a task heap separated from the system heap. The system heap may store system data accessible by the plurality of tasks. The task heap may store task data only accessible by one task of the plurality of tasks.
