不应该R3持有地址x3307？ [英] Shouldn't R3 hold address x3307?

问题描述

我从问题7

I am doing a practice question from Question 7

我不应该强调的地址必须x3307，x3308不？

Shouldn't the address I highlighted be x3307, not x3308?

我推断这一点的方式是，（第2个指令之前PC）=（1指令后PC）。

The way I reasoned this out was that (PC before 2nd instruction) = (PC after 1st instruction).

1日指令后PC为X3301。第二指令执行。因此，当时，PC，X3301将由6递增以x3307

The PC after 1st instruction is x3301. Therefore when the second instruction executes, the PC, x3301 will be incremented by 6 to x3307.

是否每个人都同意吗？还是我错过了什么和R3应实际存储x3308？

Does everyone agree? Or did I miss something and R3 should actually store x3308?

推荐答案

PC相对偏移的已经递增的PC的顶端施加，即在PC的值后，或者换句话说，所述的地址接下来的指令。

PC-relative offsets are applied on top of the already incremented PC, that is the "after" value of the PC, or in other words, the address of the following instruction.
