一、本課程設計的性質、目的、任務
《計算機組成與系統結構課程設計》是計算機學院各專業集中實踐性環節之一，是學習完《計算機組成與系統結構》課程後進行的一次全面的綜合練習。其目的是綜合運用所學計算機原理知識，設計並實現一臺模型計算機，以便鞏固所學的知識，提高分析問題和解決問題的能力。
二、本課程設計的基本理論
1、掌握算術、邏輯、移位運算實驗，熟悉ALU運算控制位的運用。
2、掌握存儲器組織、讀寫方式及與總路線組成的數據通路，掌握地址總線、數據總線的工作原理。
3、掌握指令結構和指令取指、執行工作過程。
4、掌握CPU的微程序控制原理。
三、題目
1、綜合運用所學計算機原理知識，設計並實現具有以下指令集結構的模型計算機：

其中，高4位爲指令操作碼，M爲16位存儲器地址， Rs爲源寄存器，Rd爲目的寄存器，佔2位，並規定：
|
Rs或Rd |
選定的寄存器 |
|
00 01 10 11 |
R0 R1 R2 R3 |
2、利用上述指令集編寫彙編程序，並在所設計的模型計算機上調試通過:
用累加的方法實現字節乘法（不溢出情況），被乘數：R0，乘數：R1，積：R2並輸出至I/O。
四、數據格式及指令系統
1.數據格式
模型機規定採用定點補碼錶示數據，且字長爲8位，其格式如下：
|
7 |
6 5 4 3 2 1 0 |
|
符號 |
尾 數 |
2.指令格式
模型機設計四大類指令共 條，其中包括算術邏輯指令、I/O指令、訪問及轉移指令和停機指令。
⑴ 算術邏輯指令
設計算術邏輯指令並用單字節表示，尋址方式採用寄存器直接尋址，其格式如下：
|
7 6 5 4 |
3 2 |
1 0 |
|
OP-CODE |
Rd |
Rs |
其中，OP-CODE爲操作碼，Rs爲源寄存器，Rd爲目的寄存器，並規定：
|
Rs或Rd |
選定的寄存器 |
|
00 01 10 11 |
R0 R1 R2 R3 |
⑵ 訪問指令及轉移指令
模型機設計2條訪問指令，即存數（STA）、取數（LDA），2條轉移指令，即無條件轉移（JMP）、結果爲零轉移（JZ）、有進位轉移指令（JC），指令格式爲：
|
7 6 5 4 |
3 2 |
1 0 |
|
OP-CODE |
Rd |
Rs |
|
D（低八） |
||
|
D（高八） |
||
⑶ I/O指令
輸入（IN）和輸出（OUT）指令採用單字節指令，其格式如下：
IN:
|
7 6 5 4 |
3 2 |
1 0 |
|
OP-CODE |
Rd |
0 0 |
OUT:
|
7 6 5 4 |
3 2 |
1 0 |
|
OP-CODE |
0 0 |
Rs |
⑷ 停機指令
指令格式如下：
|
7 6 5 4 |
3 2 |
1 0 |
|
OP-CODE |
0 0 |
0 0 |
HALT指令，用於實現停機操作。
1. 目標寄存器的尋址控制
1) 當OP=0、R/M=1時，將IR3、IR2作爲目標寄存器地址；
2. 源寄存器的尋址控制
1) 當XP=1時，將IR1、IR0作爲源寄存器地址。
