Abstract
A fast sub-process is provided in an operating system for a digital signal processor (DSP). The fast sub-process executes a sub-process without a kernel first determining whether the sub-process resides in an internal memory, as long as certain conditions have been satisfied. One of the conditions is that a programmer determines that the sub-process has been previously loaded into internal memory and executed. Another condition is that the programmer has ensured that a process calling the sub-process has not called any other sub-process between the last execution and the current execution request. Yet another condition is that the programmer ensures that the system has not called another overlapping sub-process between the last execution and the current execution request.
