Open publisher page 0 citations

Abstract

The TI DSP application reference framework, RF5, based on DSP/BIOS real-time kernel, is introduced in this paper. In addition, an improved DSP application framework based on RF5 is proposed to support multi-processor and typical GPP-DSP system which is called ERF5 in this paper. By using ERF5, the GPP-DSP communication, effective task thread execution and schedule, and granule of task can be improved effectively. Finally, a real video processing system based on ERF5 is introduced and the performance of ERF5 is analyzed.
