SWI异常中断和未定义异常中断指令一样,也是由当前执行的指令自身产生,当SWI指令执行时,pc的值还未更新,它指向当前指令后面第2条指令(对于ARM指令,它指向当前指令地址加8字节的位置;对于Thumb指令,它指向当前指令地址加4字节的位置),当未定义指令异常中断发生时,处理器将值(pc-4)保存到lr_svc中,此时(pc-4)指向...
ARM1176JZF-S processor has 40 registers totally: 33 general-purpose 32-bit registers seven 32-bit status registers. These registers are not all accessible at the same time. The processor state and operating mode determine the registers that are available to the programmer. Here I focus on ARM ...
The OS can configure this subset of options through a remap mechanism for these TEX[0], C, and B bits. The TEX[2:1] bits in the descriptor then become 2 OS managed page table bits. See detail of ARM1176JZF-S Technical Reference Manual 6.6.1 for TexRemap=0 configuration/TexRemap=1 ...
