Generic multimedia framework for low power DSP using RTOS
More InfoLess Info
Rapid arrival of new multimedia algorithms and storage devices demands a framework to reduce product development and customization. Generic framework in real-time operating system (RTOS) should be loosely coupled, platform independent, and have low memory and MHz footprint. Proposed framework uses tasking model, messaging and overlay scheme. Messages are used to provide services transparent across tasks and processors. Memory management is done via overlay within small on-chip memory of DSP. Framework follows standard set of API's algorithm and access storage devices makes system plug and play for new component.
