高通的MSM是mobile station modems . 移动基带处理器.带基带的手机处理器.
QRD就是高通参考设计(Qualcomm Reference Design)
PBL：APPS PBL(Application Primary Boot Loader)，主引导加载程序
RPM：Resource Power Manager，资源电源管理器
RPM（Resource Power Manager）是高通MSM平台另外加的一块芯片，虽然与AP芯片打包在一起，但其是一个独立的ARM Core。之所以加这个东西，就是要控制整个电源相关的shared resources，比如ldo，clock。负责与SMP,MPM交互进入睡眠或者唤醒整个系统。
L2 TCM：Tightly-Coupled Memory，紧耦合内存
Some ARM SoC:s have a so-called TCM (Tightly-Coupled Memory). This is usually just a few (4-64) KiB of RAM inside the ARM processor.
Due to being embedded inside the CPU The TCM has a Harvard-architecture, so there is an ITCM (instruction TCM) and a DTCM (data TCM). The DTCM can not contain any instructions, but the ITCM can actually contain data.
CDT: Configuration Data Table，包含CDB0: platform info信息和CDB1: DDR配置参数。
