[jimmy5566 (jimmy)]

A compiler cache of the total size equal to the sum of the two split caches
will usually have a better hit rate.


Increasing the depth of pipelining always increases performance.


請問上面這兩個敘述正確嗎?

麻煩各位了,謝謝!

→ privatewind:1.True 2.False
推 kai5566:1看不懂是什麼意思耶... 2確定是false
→ privatewind:1是說當資料分成兩個獨立的cache存放的hit rate較好
→ privatewind:還是一個統一的cache比較好
→ privatewind:像是MIPS pipeline在L1 cache就是採split
→ privatewind:從他圖中你就可看到instruction memory
→ privatewind:和 data memory是分開的 這是為了提升hit time
→ privatewind:但這裡是問較好的HIT RATE 就很明顯是一個CACHE
推 kai5566:哦哦   感謝樓上  了解意思了~~~3Q
