最近在看高通文档，英文缩写太多了看的蛋疼，整理记录一下。
MSM-mobile station modems . 移动基带处理器.带基带的手机处理器


QRD-高通参考设计(Qualcomm Reference Design)


APSS-应用子系统（application subsystem）


ADSP-advanced digital signal processor(DSP)


LPASS-Low Power Audio SubSystem(低功耗音频子系统)


RPM-资源功耗管理子系统
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。


Modem-调制解调(基带)处理子系统


SDI-System Debug Image系统调试镜像
HLOS APPSBL-(High-Level Operationg System，高级操作系统的SBL，指lk(little kernel))


TZBSP  -  TrustZone BSP


SMEM - shared memory


RPC - remote procedure call


PBL - primary bootloader


AMSS - Advanced Mobile Subscriber Software


QSEE - Qualcomm Secure Execution Environment


UEFI-统一的可扩展固件接口”(Unified Extensible Firmware Interface)， 是一种详细描述类型接口的标准。
这种接口用于操作系统自动从预启动的操作环境，加载到一种操作系统上。


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.
