branch target buffer 在 Re: [理工] 計組BHT BTB - 看板Grad-ProbAsk - 批踢踢實業坊 的美食出口停車場
※ 引述《imadog (凹嗚)》之銘言：
突然想到一個問題
請問BHT跟BTB 是位於CPU裡面嗎?
還是是memory的一部分啊~
當然是放在 CPU 裡呀，先想清楚 BHT (Branch History Table)
跟 BTB (Branch Target Buffer) 是拿來幹嘛的吧？
如果你今天放在 Memory 裡，你預測 Branch 的 Target Address
還要過數百個 Cycles 才能拿到，那這種最佳化根本沒有用啊！
-
一個很容易搞混的觀念是，很多人誤以為 BTB 一定要跟 BHT 搭配在一起，
但不是的。
BHT 主要是拿來記錄 Branch 決定的 "結果"，
(如果是 jump 就會是 always jump)
而 BTB 是拿來給 Instruction Fetch Unit 參考下一道指令要抓哪裡。
兩個通常都是用 PC Address 當作 index，也都是拿來盡量降低 Branch 造成的 Overhead。
