摘要
本文介绍了基于DSP/BIOS实时内核的TIDSP应用程序参考框架RF5。另外,面对目前越来越多的多处理器系统设计以及典型的GPP-DSP架构,本文提出了一种改进的DSP应用程序框架ERF5以最大化地支持这种架构。ERF5主要从GPP-DSP有效通信、任务线程的高效执行与调度以及任务线程颗粒度的合理化三个方面对RF5进行了改进,并已成功应用于实际项目。
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 he improved effectively. Finally, a real video processing system based on ERF5 is introduced and the performance of ERF5 is analyzed.
