An embedded processor has both 32 and 16-bit instructions.
16-bit instructions are a subset of the most commonly used
32-bit instructions. Compared to codes written in 32-bit
instructions, codes written in 16-bit instructions could
potentially
(a)increase or decrease I-Cache hit rate?
答案是 decrease
為什麼呢??
觀念有點想不通...
麻煩大家指導一下...
感謝~~
