| 摘 要： | 在要求时延较小的仿真系统中,声音采集与播放是一个并发互斥过程。就单核CPU下的并发互斥技术,特别是当前国内虚拟电台系统中应用的并发互斥技术进行了分析研究,针对其在多核CPU下可能存在的问题进行了讨论,在此基础上提出了一种基于录音优先算法的改进算法,并从技术对比和算法复杂度方面进行了论证。

Intercurrent and Mutex Technology of Sound Collection and Playing Based on Multi-Core PC |
| |
| Abstract: | In the low-delay simulation system,the technology of sound collection and playing is a process of intercurrent and mutex.This paper talks about the technology of intercurrent and mutex based on single-core processor,especially studies it in the visual radio system,discusses the subsistent questions based on multi-core PC,gives a sort of ameliorative arithmetic based on recording first arithmetic,demonstrate the above technology contrast and arithmetic complicated grade. |
