課程簡介

此課程目標是建造一台計算機；從Logic(Nand)開始，逐步設計Microarchitecture、ISA、OS及Algorithm，最終實現運作簡單的俄羅斯方塊小遊戲。

章節簡介

Lecture 1、2

Ideal

• All Boolean functions can implementation by not、and
• not、and can combine to nand,so we use nand for implement

For example:

(a or b) => not not(a or b) => not(not a and not b)

not => (a nand a)

Hint: Think from Proposition Logic!!

Lecture 3

Key point

• You have to know how does the DFF work clearly.

Lecture 4

Key point

How to use Variable symbol?

• 寫入「位址」與寫入「內容」的差別

@SCREEN  D=A
@i       A=D+M   // A = SCREEN + i
M = ...          // 對該位址寫資料

Lecture 5
