Abstract: Systems and methods for processing data from priority-based operating system threads within a realtime component are described. The component submits blank buffers to hardware. The component receives data from priority based operating system threads and processes and writes the data from within an independent second real-time thread to buffers before the buffers into which the data is written are used by the hardware. Hardware buffers are created offset from memory page boundaries such that the least significant bits of any memory address referencing the start of the buffer uniquely identify it and can be used as an index into a circular buffer queue to determine which buffer is currently being processed. Data is always processed and written into a buffer that is a predetermined range of buffers in front of the buffer currently being processed by the hardware.

Abstract: Systems and methods for processing priority-based application threads on a realtime component are described. A mixing component submits blank buffers to the realtime component. The mixing component receives application thread data according to a priority-based schedule and writes the data using a second real-time thread to the buffers before the buffers into which the data is written are processed. Buffers are created on memory page boundaries with an offset into the memory page such that the least significant bits of a virtual memory address referencing the memory page can be used as an index into a circular buffer queue to determine which buffer is currently being processed. When writing into a buffer, a buffer that is a predetermined range of buffers behind the buffer currently being processed is used.

Abstract: A method and system for placing a computer in a reduced power state is provided. In a preferred embodiment of the present invention, the system monitors the performance of a monitored activity of a program executing. The system determines whether the program is performing the monitored activity regularly. If the program is performing the monitored activity regularly, the system places the computer in a reduced power state.
