Methods For Running Priority-Based Application Threads On A Realtime Component

摘要

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.
