    摘要： Methods and arrangements are provided for use in multiple user computing environments. These methods and arrangements can be configured to allow for a plurality of separate and concurrent desktops and workspaces within the shared computing environment. One method includes creating a separate desktop thread for each user that is authenticated during a logon process, creating a separate desktop associated with each desktop thread, and maintaining a list of desktop threads that are created. In this manner, several users can be logged on simultaneously. In certain implementations, the method further includes establishing a separate user environment associated with each desktop and launching a separate user shell associated with each desktop. The list of desktop threads allows for selective and/or automatic switching from a first desktop to a second desktop without terminating a desktop thread associated with the first desktop. The methods and arrangements are also applicable to remote process logon and switching.

    摘要： Methods and apparatuses are provided for controlling application software while switching between sessions in a multi-session computing environment. An apparatus includes memory coupled to switching logic and application program managing logic. The switching logic is configured to selectively switch console control of a computing device between at least two user kernel sessions that are maintained in the memory. The application program managing logic is configured to selectively control at least one application program that is operatively configured within at least one of the user kernel sessions. For example, the application program managing logic can be configured to stop the operation, re-start certain application programs, notify application programs about switching events, and/or adjust the playback of audio and/or video signals associated certain application programs.

    摘要： Various techniques are described to protect secrets held by closed computing devices. In an ecosystem where devices operate and are offered a wide range of services from a service provider, the service provider may want to prevent users from sharing services between devices. In order to guarantee that services are not shared between devices, each device can be manufactured with a different set of secrets such as per device identifiers. Unscrupulous individuals may try to gain access to the secrets and transfer secrets from one device to another. In order to prevent this type of attack, each closed computing system can be manufactured to include a protected memory location that is tied to the device.

    摘要： A method and computer-readable medium perform a pre-boot scan of an emulated binary to detect a function that is above a predetermined complexity threshold. The detected function may then be precompiled during a boot-up process. The pre-boot scan may also detect a function that falls below a second predetermined complexity threshold. The detected function may be placed inline with the code body. Just-in-time translation may then be performed at runtime.

    摘要： A JIT binary translator translates code at a function level of the source code rather than at an opcode level. The JIT binary translator of the invention grabs an entire x86 function out of the source stream, rather than an instruction, translates the whole function into an equivalent function of the target processor, and executes that function all at once before returning to the source stream, thereby reducing context switching. Also, since the JIT binary translator sees the entire source code function context at once the software emulator may optimize the code translation. For example, the JIT binary translator might decide to translate a sequence of x86 instructions into an efficient PPC equivalent sequence. Many such optimizations result in a tighter emulated binary.

    摘要翻译： JIT二进制翻译器将代码转换为源代码的功能级别而不是操作码级别。 本发明的JIT二进制翻译器从源流中获取整个x86函数而不是指令，将整个函数转换为目标处理器的等效函数，并在返回到源流之前一次执行该函数， 从而减少上下文切换。 此外，由于JIT二进制翻译器一次看到整个源代码功能上下文，因此软件仿真器可以优化代码转换。 例如，JIT二进制翻译器可能决定将x86指令序列转换为有效的PPC等效序列。 许多这样的优化导致更严格的仿真二进制。

    摘要： The invention provides a circuit for reading data from a data carrier, the circuit comprising a reading unit for reading data from the data carrier; and a controller for controlling the circuit. The circuit further comprises a detection unit for detecting a format of the data carrier; and the controller is configurable to control the circuit to read data from the data carrier in accordance with the detected data carrier format. In this way, for example, an ATAPI engine can be used in a consumer electronics device to play back music from a Super Audio CD. The invention also provides an apparatus, method and data carrier.
