摘要： Systems, methods, and computer-readable media supporting thread abstraction in Java are provided. In some illustrative embodiments, a system is provided that includes a Java execution flow class that represents an execution flow context, an execution flow scheduler object including a Java native execution flow activation method, a Java virtual machine, a Java scheduler that executes on the Java virtual machine, and a Java thread class that extends the execution flow class. The execution flow class includes an execution flow execution method and a constructor that creates an execution flow context. The Java thread class includes an execution flow execution method that overrides the execution flow execution method of the execution flow class. In this system, a thread object including one or more instructions of a thread is instantiated using a custom thread class that extends the Java thread class, the constructor creates an execution flow context for the thread, and the Java scheduler invokes the execution flow activation method to switch from a currently executing execution flow context to the thread execution flow context to execute the one or more instructions.

摘要： An electronic system comprises a processor, memory coupled to the processor, and an application programming interface that causes an embedded garbage collection object to be active. The memory stores one or more objects that selectively have references from root objects. The embedded garbage collection object preferably uses control data to cause objects to be removed from said memory, the removed objects comprise those objects that were created while an embedded garbage collection object was active and that do not have references from root objects.

摘要： A processor adapted to couple to external memory. The processor comprises a controller and data storage (e.g., cache memory). The data storage is configurable to operate in either a cache policy mode in which a miss results in an access of the external memory or in a scratch pad policy mode in which a miss does not result in an access of the external memory. The data storage comprises a first portion and a second portion, and only one of the portions is active at a time. The non-active portion is unusable to store or retrieve data (e.g., Java local variables). When the active portion does not have sufficient capacity for additional data to be stored therein, the other portion becomes the active portion.

摘要： A process and associated system comprise pre-allocating a portion of memory in a first processor based upon a control input and determining in a second processor if the portion of the pre-allocated memory can satisfy a memory allocation request. Further, if a portion of pre-allocated memory can satisfy a memory allocation request, the technique includes assigning the pre-allocated portion of memory to the allocation request. However, if a portion of pre-allocated memory cannot satisfy a memory allocation request, the technique includes allocating a portion of memory in the first processor to the allocation request.

摘要： The problems noted above are solved in large part by a method and system for implementing a micro-sequence based security model. Specifically, micro-sequences and JSM hardware resources may be employed to construct a security model invisible to applications, and when memory constraints are in place, extend a complex security model in JSM code by implementing a micro-sequence security trigger. A method is disclosed, comprising defining a micro-sequence based security policy. The method also comprises determining whether an instruction accesses a privileged resource. When not already in privilege mode and not executing a micro-sequence, the micro-sequence based security policy is applied to the instruction to control access to the privileged resource according to the security policy.

Some illustrative embodiments are a processor comprising fetch logic that retrieves an instruction from a memory, the instruction being part of a program, and decode logic coupled to the fetch logic which decodes the instruction, wherein the instruction decoded by the decode logic triggers execution of a micro-sequence to enter the instruction in a control flow graph.
