基带芯片物理层控制方案的设计

对多核基带芯片物理层控制方案进行了简单的讨论,提出了一种用于GSM移动终端基带芯片物理层控制(L1C)的方案,根据GSM的帧结构设计了基时钟电路,并以物理层信号处理流程为依据,建立了物理层上下行的调度时序,初步完成了基带芯片SoC系统多核之间的任务调度和时序控制。

Design of physical layer controller of scheme baseband chip

The physical layer controller（L1C）scheme of the multi-cores baseband chip is simply discussed,and a physi-cal layer control scheme for GSM MT baseband chip is proposed. According to the frame structure of GSM,a clock-based circuit is designed. The scheduling sequence for physical layer up and down is established based on the signal treatment process,the task scheduling and timing control among multi-cores in baseband chip SoC are completed initially.
