One embodiment of the present invention provides a system for emulating computer viruses and/or malicious software that operates by patching additional program instructions into an emulator in order to aid in detecting a computer virus and/or malicious software within suspect code. During operation, the system loads a first emulator extension into the emulator. This first emulator extension includes program instructions that aid in the process of emulating the suspect code in order to detect a computer virus and/or malicious software. The system also loads the suspect code into an emulator buffer. Next, the system performs an emulation using the first emulator extension and the suspect code. This emulation is performed within an insulated environment in a computer system so that the computer system is insulated from malicious actions of the suspect code. During this emulation, the system determines whether the suspect code is likely to exhibit malicious behavior. In one embodiment of the present invention, loading the first emulator extension into the emulator involves loading the first emulator extension into the emulator buffer within the emulator. In this embodiment, performing the emulation involves emulating the program instructions that comprise the first emulator extension.

Protection against a malicious set of program instructions (e.g., a malicious program) executable by a process virtual machine. The program instructions of process virtual machine are augmented to establish an exception monitoring module within the process virtual machine. When the process virtual machine executes a subject set of program instructions, the exception monitoring module detects a security policy violation exception occurring as a result. In response thereto, the exception monitoring module gathers context information representing circumstances surrounding the occurrence of the exception, and provides the context information for analysis of a presence of malicious code. The exception monitoring module determines, based on a result of the analysis, whether to permit further execution of the subject set of program instructions by the process virtual machine.

A system and method for instrumenting program instructions. A processing system includes a compiler and a profiler. The profiler is configured to instrument an application by inserting one or more instrumentation instructions in the application. During execution of the application, execution is monitored and a particular condition is detected. Responsive to the condition, a portion of the code which corresponds to the detected condition is identified. A request is conveyed for recompilation of code which corresponds to code. Prior to recompilation of the code, the profiler instruments the portion of code. Execution and monitoring of the execution continue, and instrumentation/recompilation may be repeated. Initially, relatively little of the application code may be instrumented. As execution and monitoring continues, more and more of the application code may be dynamically instrumented during execution.

A touch sensitive apparatus and method of operation to improve visual feedback and visual perception of tactile input to an operator. The apparatus includes a touch screen device or display having a touch overlay, a processor and stored program instructions in a memory in which a three-dimensional graphical image, such as a key element, is created in the apparatus and shown on the display as an input device or keypad to the processor. Each key element includes a beveled surface surrounding a flat surface. When a displayed key element is touched by a probe, such as a finger, the screen area about the displayed key element and the finger, visually enlarges or "splats" confirming the selection of the particular key. Concomitantly or simultaneously, the key element detents or depresses within the key pad, changes color and bevel size further verifying the key selection to the operator thereby creating a sense of key movement and visual perception of tactile input to the operator aiding in the operation of the key pad. The simultaneous visual key enlargement, visual detenting and change in key color and bevel size upon key selection in a touch sensitive apparatus improves the feedback to the operator in the selection and confirmation of a key element actuated by the operator.

In a digital system with a processor coupled to a paged memory system, the memory system may be dynamically configured using a memory compaction manager in order to allow portions of the memory to be placed in a low power mode. As applications are executed by the processor, program instructions are copied from a non-volatile memory coupled to the processor into pages of the paged memory system under control of an operating system. Pages in the paged memory system that are not being used by the processor are periodically identified. The paged memory system is compacted by copying pages that are being used by the processor from a second region of the paged memory into a first region of the paged memory. The second region may be placed in a low power mode when it contains no pages that are being used by the processor.

A just-in-time (JIT) compiler typically generates code from bytecodes that have a sequence of assembly instructions forming a "template". It has been discovered that a just-in-time (JIT) compiler generates a small number, approximately 2.3, assembly instructions per bytecode. It has also been discovered that, within a template, the assembly instructions are almost always dependent on the next assembly instruction. The absence of a dependence between instructions of different templates is exploited to increase the size of issue groups using scheduling. A fast method for scheduling program instructions is useful in just-in-time (JIT) compilers. Scheduling of instructions is generally useful for just-in-time (JIT) compilers that are targeted to in-order superscalar processors because the code generated by the JIT compilers is often sequential in nature. The disclosed fast scheduling method has a complexity, and therefore an execution time, that is proportional to the number of instructions in an instruction block (N complexity), a substantial improvement in comparison to the N2 complexity of conventional compiler schedulers. The described fast scheduler advantageously reorders instructions with a single pass, or few passes, through a basic instruction block while a conventional compiler scheduler such as the DAG scheduler must iterate over an instruction basic block many times. A fast scheduler operates using an analysis of a sliding window of three instructions, applying two rules within the three instruction window to determine when to reorder instructions. The analysis includes acquiring the opcodes and operands of each instruction in the three instruction window, and determining register usage and definition of the operands of each instruction with respect to the other instructions within the window. The rules are applied to determine ordering of the instructions within the window.

Systems, methods, and computer-readable storage media for performing a visual rewind operation in an image editing application may include capturing, compressing, and storing image data and interaction logs and correlations between them. The stored information may be used in a visual rewind operation, during which a sequence of frames (e.g., an animation) depicting changes in an image during image editing operations is displayed in reverse order. In response to navigating to a point in the animation, data representing the image state at that point may be reconstructed from the stored data and stored as a modified image or a variation thereof. The methods may be employed in an image editing application to provide a partial undo operation, image editing variation previewing, and/or visually-driven editing script creation. The methods may be implemented as stand-alone applications or as program instructions implementing components of a graphics application, executable by a CPU and/or GPU.

Various embodiments of systems and methods for performing volume-based incremental backups are disclosed. A method may involve generating a snappoint of a volume. The snappoint indicates which portions (e.g., blocks or extents) of the volume have been modified between a time at which the snappoint was generated and a time at which a subsequent snappoint was generated. The method may also involve accessing information mapping the file to the volume and, if the snappoint identifies as having been modified any blocks of the volume to which the file maps, copying those blocks from the subsequent snappoint to the backup device. Portions not identified as having been modified by the snappoint are not copied. Program instructions implementing such a method may be stored on a computer accessible medium.
