It is desirable to share the resources of a single DSP microprocessor among multiple concurrent audio tasks, but this poses a variety of practical problems. In this paper, the features of general-purpose operating systems are contrasted with the needs of typical audio DSP processes, and the architecture of a simple yet powerful real-time DSP kernel is proposed.
