POP {reglist,PC}这条指令引起处理器转移到从堆栈弹出给PC的地址,这通常是从子程序返回,其中LR在子程序开头压进堆栈。这些指令不影响条件码标志。 指令示例: PUSH {R0,R3,R5} PUSH {R1,R4-R7} PUSH {R0,LR} POP {R2,R5} POP {R0-R7,PC} 了解了之后我们就可以用verilog写一个POP和PUSH指令的实现。

push {r1, r2} pop {r1, r2} 他们的先后顺序为 push {r2} push {r1} pop {r1} pop {r2}) 这里已经到最后了,拿比较常见的push {r1, lr} pop {r1,pc} 举这个例子 mov lr,#0xpc+4 mov pc,#0x地址+8 //bl #0x地址 地址: sub sp, #4 str lr, [sp]//前面说了lr的值为bl指令下一条...
