Previous Topic

The previous post has elaborated 3 things we need to implement: Half Adder, Full Adder and 16-bit Number Adder. The next is a simpler one: 16-bit Incrementor.

Other Two Chips

16-bit Incrementor

Tip: A single bit “0” or “1” can be represented by true or false in HDL.

ALU

Tips:

Adding two numbers in binary representation is pretty simple. Here we are gonna build an Adder for binary numbers.

Starter (Unit 2.2)

Why does the Adder matter most?

Adder + Negative representation = Subtraction

Multiplication and Division are not hardware’s work, but software’s.

Three steps to build an Adder

Binary and Arithmetic (Unit 2.1)

Project 1 Goal (Unit 1.8)

Given a NAND, build all the gates.

课上给了Project 1的其中几个chips的讲解。讲了Mux, DMux, And16 和 Mux4Way16。

这两个单元主要是介绍了软件怎么用，怎么test和生成output。
简介了Hardware Description Language (HDL) (unit 1.4)

Hardware simulator (unit 1.5)

Feel free to “kick the tires”!

• The simulator is written in Java.
• The download link is here.

这一章除了复习了一遍以前学过的与非或逻辑门，还介绍了为什么一个与非门就能表示所有的逻辑表达式。

Boolean logic (unit 1.1 – 1.3)

Algebra rules

• Commutative laws

Introduction

This is the final project of INFSCI 2140 Information Storage and Retrieval. We built a search engine of movie lines. Users can input a phrase or a complete sentence and it returns a list of best matched movies with excerpts.
