因此，只要将指令地址提供给处理器(如Branch指令)，就会忽略低阶的两位。
Thus, whenever instruction addresses are presented to the processor (as in Branch instructions), the low-order two bits are ignored.
他们发现其中五位病人可以根据指令想象打网球或是穿越一间熟悉的房子。
They found that five of these 54 patients responded to commands to imagine playing tennis or navigating through a familiar house.
问题的关键是 SPU 有几个条件指令，例如 selb、 shufb 和位操作，它们可以不用分支就能实现条件操作。
The key is that the SPU has several conditional instructions, such as selb, shufb, and the bit operations, which allow conditional operations to occur without branching.
