## Homework
### [Homework 1. SIC 組合語言 – 字串轉換](https://github.com/davidho0403/system-programming/tree/main/homework/HW1)
在 Device ‘F1’ 中有一字串由大小寫英文字母所組成（字串的結束字元為 ‘$’，其 ASCII 值為 0x24）。請用 SIC 的指令集寫一組合語言程式，完成以下的功能：
請從 Device ‘F1’ 中讀取字串，如果所讀取的字元為小寫，請將其轉換為大寫字元並寫入 Device ‘F2’ 中 （如果所讀取的字元為大寫，則不變，直接寫到 Device ‘F2’ 中）。
完成基本功能者滿分90分，將讀取字元及寫入字元分別以副程式來撰寫者滿分100分。
### [Homework 2. SIC/XE 組合語言 – 9x9 乘法表](https://github.com/davidho0403/system-programming/tree/main/homework/HW2)
請用 SIC/XE 的指令集寫一組合語言程式，在 Device ‘F2’ 中印出如下的 9x9 乘法表，請滿足以下要求：
1. 寫出印一個數字（Register A 的值）的副程式 50 分
2. 以雙迴圈的方式來列印，滿分最高 90 分
3. 你的輸出結果需要對齊，對齊 100 分

### [Homework 3. Assembler – Pass 1](https://github.com/davidho0403/system-programming/tree/main/homework/HW3)
請參考課堂中提供的程式 (1-token.c, 2-optable.c 及 3-asm_pass1_u.c) 及 Figure 2.4(a) 的演算法完成 SIC/XE Assembler 的 Pass 1。你的程式要完成：
1. 如 Figure 2.2 秀出每一行組合語言程式的指令，並在前面印出 LOCCTR 的值(該行最後不需印出 Object Code ，印不印出註解均可)
2. 印出 ASM Program 的長度
3. 請在最後印出 SYMTAB 的 Symbol 及其對應值。
