工具鏈與組譯流程
本章把第 18 章的指令「用起來」:介紹 GNU 工具鏈的組譯與連結流程、常用偽指令與組譯器指示詞;詳述 RISC-V ——參數與回傳值的暫存器分配、呼叫者/被呼叫者保存責任、堆疊框架的建立與拆除;並以迴圈、陣列、字串、遞迴(階乘與費氏)等完整範例示範慣用寫法。這些程式將於第 26 章載入我們自製的 Verilog CPU 上實際執行。

基礎集之外,真實的 RISC-V 處理器總會搭配若干標準擴展。本章詳述與本教材實作最相關的 (乘法與除法):八條指令的語意、mulh 家族的用途、除零與溢位的定義行為;介紹 (16 位元壓縮指令)的編碼思想與硬體代價;概覽 (原子操作)如何支撐多核同步;最後討論「該選哪些擴展」的工程取捨。

使用者層指令(第 18 章)之外,處理器還需要一套「管理機器」的機制:這就是 RISC-V (ISA Manual Volume II)。本章介紹三級特權模式(M/S/U)與其分工;及六條 Zicsr 指令;的完整硬體流程(mtvec/mepc/mcause/mstatus 的角色與 mret 返回);計時器與軟體中斷(CLINT)、外部中斷(PLIC);以及 分頁虛擬記憶體如何落實第 8 章的概念。這是把第一部作業系統支援、第二部指令

本章為第三部的工具課:以「做 CPU 需要什麼」為範圍,精講 Verilog 硬體描述語言。核心觀念只有一個——:每一行都對應真實的閘、導線與正反器,所有 always 區塊永遠並行存在。我們將依序建立:模組與埠、wire/reg 與四值邏輯、組合邏輯(assign 與 always @(*))、時序邏輯(always @(posedge clk)與非阻塞指定)、參數化、記憶體陣列與 readmemh、測試平台寫法,以及新手最常犯的錯誤

從本章起,我們動手建造一顆完整的 RV32I 處理器。策略是「先單週期、後管線」:單週期機器每個時脈執行完一整條指令,沒有危障,是理解資料路徑的最佳起點。本章完成所有的 Verilog 實作與原理講解:ALU、暫存器檔、立即值產生器、分支比較器、主控制器、指令/資料記憶體。每個模組都對應前面章節的理論:ALU 對應第 9 章、立即值對應第 11 章、控制訊號對應第 15 章。完整原始碼位於專案的 目錄,已以 Icarus Verilog
