Chap08 Syntax and Grammars

Grammar

• represent certain knowledges of what we know about a language
• General criteria
  • linguistic naturalness
  • mathematical power
  • computational effectiveness

Context-free grammars(CFG)

• Alias
  • Phrase structure grammars
  • Backus-Naur form
• More powerful than finite state machine
• Rules
  • Terminals
    • words
  • Non-terminals
    • Noun phrase, Verb phrase ...
  • Generate strings in the language
  • Reject strings not in the language
  • LHS → RHS
    • LHS: Non-terminals
    • RHS: Non-terminals or Terminals
  • Context Free
    • probability of a subtree does not depend on words not dominated by the subtree(subtree出現的機率和上下文無關)

假設已經知道編譯流程
[介紹]
gcc and g++分別是gnu的c & c++編譯器 gcc/g++在執行編譯工作的時候，總共需要4步
1.預處理,生成.i的文件[預處理器cpp]
2.將預處理後的文件不轉換成彙編語言,生成文件.s[編譯器egcs]
3.有彙編變為目標代碼(機器代碼)生成.o的文件[彙編器as]
4.連接目標代碼,生成可執行程序[鏈接器ld]

此篇文章十分清楚易懂，可作為初學之用

Chap04 Network Layer

transport layer: between two processes
network layer: between two hosts and router (may also involve intervening routers in case of VCs)

Chap07 Pipelining (II)

Data Dependence Detection
Hazard conditions:

• EX hazard
  • EX/MEM.RegisterRd = ID/EX.Register Rs or Rt
• MEM hazard
  • MEM/WB.RegisterRd = ID/EX.RegisterRs or Rt
  • Ex/MEM.RegisterRd != ID/Ex.RegisterRs(優先選EX)
• RegWrite == true
• RegisterRd != $0
