• A novel scheduling method for asynchronous multirate/multi-task processing by programmable digital signal processors(DSPs)has been developed. This mixed scheduling method combines static and dynamic scheduling, and avoids runtime overheads due to interrupts in context switching to realizes asynchronous multirate systems. The processing delay introduced when using static scheduling with static buffering is avoided by introducing deadline scheduling in the static schedule design. In the developed software design system, a blockdiagram description language[1]is extended to describe asynchronous multi-task processing. The scheduling method enables asynchronous multirate processing, such as arbitrary-samplingratio rate conversion, asynchronous interface, and multimedia applications, to be efficiently realized by programmable DSPs.
