摘要： A processing system is set forth that includes a processor, read only memory storing an operating system image file accessible by the processor, and random access memory that is also accessible by the processor. The processing system also includes a boot program that is executable by the processor to initialize the processing system in response, for example, to a power-on event, reset event, or a wake-up event. A power-on event occurs when power is initially provided to the processing system while a wake-up event occurs when the processing system is to exit a low-power mode of operation. A reset event occurs when, for example, a fault is detected that causes the system to restart. The boot program selectively performs a full boot copy of the operating system image file from the read only memory to the random access memory or a fast boot copy of only predetermined portions of the operating system image file from the read only memory to the random access memory. For example, the boot program may execute the full boot copy operation in response to the power-on event and the fast boot copy operation in response to the wake-up event and/or reset event. Further, the boot program may limit execution of the fast boot copy operation to those instances in which the random access memory passes an integrity check of the contents of one or more areas containing selected portions of the operating system copied from the read only memory during a prior full boot copy operation.

摘要： A system for meeting demanding boot time requirements, such as those timing requirement mandated by vehicle telematics systems, is described. Current computer systems use expensive hardware like coprocessors to service requests, such as input/output requests, that have timing requirements which are less than the time required to load the operating system into memory. Instead, a mini-driver may be initialized early in the boot process before the operating system is loaded, to service these requests. For example, the mini-driver may buffer incoming data, and/or reply to incoming messages. After the operating system has loaded, a second device driver may be initialized, and the mini-driver may be transitioned to the second driver.

摘要： A system is set forth that comprises a processor, such as a single processor or symmetric multiprocessor, and one or more memory storage units. The system also includes software code that is stored in the memory storage units. The software code is executable by the processor and comprises code for generating a plurality of adaptive partitions that are each associated with one or more software threads. Each of the adaptive partitions has a corresponding processor budget. The code also is executable to generate at least one sending thread and at least one receiving thread. The receiving thread responds to communications from the sending thread to execute one or more tasks corresponding to the communications. A scheduling system also forms at least part of the code that is executable by the processor. In operation, the scheduling system selectively allocates the processor to each sending and receiving thread based, at least in part, on the processor budget of the adaptive partition associated with the respective thread. In this type of sending/receiving environment, the scheduling system bills the processor budget of the adaptive partition associated with the sending thread for processor allocation used by the receiving thread to respond to communications sent by the sending thread.

摘要： A system is set forth that includes a processor, one or more memory storage units, and software code stored in the one or more memory storage units. The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of the plurality of adaptive partitions has a corresponding processor time budget. One or more of the process threads are designated as critical threads. Each adaptive partition associated with a critical thread is assigned a corresponding critical time budget. The software code also includes a scheduling system that is executable by the processor for selectively allocating the processor to run the process threads based, at least in part, on the processor time budgets of the respective adaptive partitions. The scheduling system may allocate the processor to run a critical thread based on the available critical time budget of the associated adaptive partition even when the processor time budget of the associated adaptive partition has been exhausted. In one example, the scheduling system functions SO that it only bills the critical time budget of an adaptive partition for time used to run an associated critical thread when the processor is overloaded and the critical time budget for the adaptive partition is concurrently exhausted. Methods of implementing such a system are also set forth.

摘要： A system is set forth that includes a processor, one or more memory storage units, and software code stored in the one or more memory storage units. The software code is executable by the processor to generate a plurality of adaptive partitions that are each associated with one or more process threads. Each of the plurality of adaptive partitions has a corresponding processor budget that is assigned to it. The process threads include a mutex holding thread and a mutex waiting thread. The mutex holding thread is associated with a first adaptive partition and may gain exclusive access to a mutex object. The mutex waiting thread is associated with a second adaptive partition and must wait for access to the mutex object while the mutex object is held by the mutex holding thread. The software code further includes a scheduling system that selectively allocates the processor to run the process threads based, at least in part, on the processor budget of the associated adaptive partitions. The scheduling system bills processor allocation used to run the mutex holding thread to the processor budget of the second adaptive partition when the processor budget of the first adaptive partition has been exhausted.
