Abstract: Multiple versions of a runtime system, such as a software emulation application that emulates a legacy hardware architecture, are allowed to co-exist in the memory of a new hardware architecture. The operating system software of the new hardware architecture reads configuration data from a database or table to decide which version of the runtime system is desirable for an application program or game that is being loaded or is currently running, and, if a match is found, only that runtime system is invoked. To reduce storage footprint, the different versions of the runtime system may be stored using “differential patching” techniques. In this configuration, the operating system will always launch the same basic runtime system binary, but it will select a different differential patch to apply at run-time based on the title as determined during the database lookup.

Abstract: The invention is a technique that allows very efficient execution of an instruction set simulator (ISS) when certain code fragments are simulated. They occur frequently in operating systems, when a processor waits for something to occur. These loops perform very little, if any, computation. An automatic analysis of the code fragments is performed to determine whether they can be transformed to “fast forward” when execution loops through the code fragment. This is done by the creation of a function g, that takes a number of state changes as an input and can compute the state at a time T by a single application of the function, rather than applying the next state function repeatedly until time T is reached. An important aspect of the resulting optimization is that it produces exactly the same simulated result as compared to when it is not applied, i.e. the optimization is non-intrusive.

Abstract: A method for configuration of an Auxiliary Processing Unit (APU) of multiprocessor system is presented. The multiprocessor system has at least a Main Processing Unit (MPU) coupled to the APU via a communication link. The APU has at least a first memory and a second memory. The method includes a plurality of steps. At step the first memory is divided into an application sector, a boot sector and a common sector. At another step interrupts of the APU except interrupt/s that is/are being received via the communication link are disabled. At a further step interrupt vector/s pertaining to the communication link is/are mapped to the boot sector of the first memory. At another step a configuration code is received selectively into the application sector of the first memory and into the second memory. At a further step the interrupt/s that is/are being received via the communication link are disabled. At a further step the common sector of the first memory is updated from the second memory.

Abstract: A method and system are described for migrating test scripts written for a current test tool (CTT) to a new test tool (NTT). A conversion tool sets the CTT in a playback mode and the NTT in a record mode. The CTT provides actions to an application under test (AUT) causing objects to be created and modified. The NTT monitors the actions of the CTT and creates a script to mimic the actions of the CTT. The current test script is modified to add comments, and translated using standard translation tools. Application-specific statements do not translate and are replaced with those previously created by the NTT in the record mode. This results in a script that performs the same functions as the original test script.

Abstract: A method is provided that speeds up software testing using abbreviation of software tests that skips the execution of a portion of the software test. Intermediate results are generated for one or more software tests, with each intermediate result corresponding to a software test, and a respective key is generated from each intermediate result. A determination is made whether the respective key for each intermediate result is stored in a file cache used for storing files under keys. Generation of a final result for the corresponding software test of each intermediate result is bypassed in response to the respective key being present in the file cache. A final result for the corresponding software test of each intermediate result is generated from the intermediate result in response to the respective key not being present in the file cache. The respective key is stored in the file cache in response to generation of each final result.

Abstract: An incremental collector can include memory pages, preferably virtual memory (VM) pages containing objects. A bit or byte map is created with one entry corresponding to each VM page. The VM page being collected is first write-protected and then the reachable objects are copied or relocated. Application induced changes to objects that have already been relocated are flagged in the map. Later the collector will suspend the application, scan the map and update the relocated objects that were changed and update the references to these objects. In one embodiment aimed at concurrent collecting, the map is copied to a second map, and the second map is scanned for changes that are propagated as before. The application may be suspended on the last pass through the map for the updating of remaining relocated objects by scanning the first map. The incremental collector can be a Train algorithm.

Abstract: A list of program instructions are mapped into memory addresses to form an executable program by simulating their execution in turn so as to determine a memory address of a next program instruction to be executed. That memory address is then examined to determine if a program instruction has already been mapped thereto. If the memory address is empty, then the next program instruction from the list is mapped to that empty memory address and the execution of that next program instruction is simulated and the process repeated. If the memory address is not empty, then the program instruction read from that memory address is simulated again and the process repeated.

Abstract: A method of testing a process that has undergone modification. The process consists of multiple steps, and execution of the process involves interaction with multiple interfacing systems. A step consists of, e.g., sending a transmission to an interfacing system. The process is executed in normal fashion by sending transmissions to interfacing systems and obtaining responses to the transmissions from the interfacing systems. The transmissions and the responses thereto obtained from the interfacing systems are stored in a simulator. After the process is modified by modifying a step of the process, the modified process is executed in such a manner that transmissions are sent to the simulator rather than to the interfacing systems. The simulator sends responses to the transmissions. It is determined whether the responses received from the simulator are the expected responses, based on the modification made to the process.

Abstract: A program execution data trace is created by instrumenting a program to record value sets during execution and an instruction trace. By simulating instructions either backward or forward from a first instruction associated with a recorded value set to a second instruction according to the instruction trace, a value set is determined for the second instruction. Backward and forward simulation can be combined to complement each other.

Preferably, one or more probes is inserted into the program to save values of particular variables whose value may be difficult to determine. Preferably, the instruction trace is displayed alongside and correlated with the data trace.

Abstract: Techniques for determining effects, on a system, of values for a parameter that is used to manage memory for the system include generating data that indicates a workload and an actual performance of the system. The data is generated while processing the workload within the system using a first value for the parameter. Based on the data, an estimated performance is generated. The estimated performance is a performance that the system would have experienced if a second value for the parameter had been used to process the workload. The second value is different from the first value for the parameter. Using these techniques, an administrator can determine what change in system performance could be achieved by changing a value of the memory management parameter. Therefore the system administrator can better determine whether to make the change in the value of the memory management parameter.

Abstract: Methods and apparatus automate creation of code for system level simulations from hardware representations, specifically RTL representations. In one approach, individual RTL hardware modules are analyzed to generate code for corresponding system level modules. This is accomplished by taking a mapped netlist for a register transfer level (RTL) representation of the hardware module and converting it to what can be termed a “system level netlist.” This system level netlist contains “system level instances” corresponding to “hardware cells” of the mapped netlist. A mapped netlist includes hardware cells corresponding to programmed hardware units of a target hardware device. The method generates corresponding functional representations (code for system level simulation) from these hardware cells. This functional representation is referred to herein as a system level instance. System level instances are generated for each of the hardware cells in a given hardware module.
