ARM Instruction
1. The condition field：ARM的任何指令都是条件执行指令，该条件位于指令的[31:28]。N、Z、C、V 比特决定指令是否执行。不同的编码对应不同的含义。
2.Branch instructions：B, BL,BLX,BX,BXJ
3.Data-processing instructions:AND,EOR,SUB,RSB,ADD,ADC,SBC,RSC,TST,TEQ,CMP,CMN,ORR,MOV,BIC,MVN
4.Multiply instructions:MUL,MLA,SMULxy,SMLAxy,SMLALxy,SMULWy,SMLAWy,SMMUL,SMMLA,SMMLS,SMUAD,SMUSD,SMLAD,SMLSD,SMLALD,SMLSLD
5.Parallel addition and subtraction instructions:ADD16,ADDSUBX,SUBADDX,SUB16,ADD8,SUB8.每个指令均可以有6个前缀：S，Q，SH，U，UQ，UH
6.Extend instructions：XTAB16，XTAB，XTAH，XTB16，XTB，XTH，每个指令均可以有两个前缀：S，U
7.Other miscellaneous instructions：PKHBT，PKHTB，REV，REV16，REVSH，SEL，SSAT，SSAT16，USAT，USAT16
8.Status register access instructions：MRS，MSR，CPS，SETEND
9.Load and store instructions：LDR，STR
10.Load and Store Multiple instructions：STM，LDM
11.Exception-generating instructions：BKPT，SWI
12.Coprocessor instructions：CDP，LDC，MCR，MCRR，MRC，MRRC，STC
13.Extending the instruction set：PKH, SSAT, SSAT16, USAT, USAT16, SEL, SMLAD, SMLSD, SMLALD, SMUAD, SMUSD,USAD8, USADA8,REV, REV16, REVSH
