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。-In this paper, based on the DSP/BIOS real-time applications TIDSP core fr a me of reference RF5. In addition, the face of the growing number of multi-processor system design, as well as typical GPP-DSP architecture, this paper proposes an improved fr a mework for DSP applications ERF5 to maximize support for this architecture. ERF5 mainly from the GPP-DSP effective communication, efficient implementation of task-thread tasks threads and scheduling, as well as particle size of the three aspects of the rationalization of RF5 improved, and has been successfully applied in practical projects.
