Bit, Bytes and Logical Gates Abstraction.

Project description

BitJoy

Bit, Bytes and Logical Gates Abstraction.

About

Repository to 'Padrões de Projeto' subject at university. A height level Bit/Bytes and logical circuits abstractions.
Also Udacity Machine Learning Engineer Nanodegre program to add these package to PyPi.

Usage

Installing

pip install bitjoy

Starting with Bit

Importing and instantiating Bit class.

from bitjoy.dtypes import Bit

zero = Bit(0)
# ZeroBit(0)
one = Bit(1)
# OneBit(1)

Creating a bit passing 0 in the __init__ method, it will create another class: ZeroBit. The same away, passing 1, it will create a OneBit.

Logical Gates

There is also support to logical operators (called logical gates or logical circuits).

from bitjoy.dtypes import LogicalOperator
  • NOT
LogicalOperator.not_(zero)
# OneBit(1)
LogicalOperator.not_(one)
# OneBit(0)
  • OR
LogicalOperator.or_(zero, zero)
# ZeroBit(0)
LogicalOperator.or_(zero, one)
# OneBit(1)
LogicalOperator.or_(one, zero)
# OneBit(1)
LogicalOperator.or_(one, one)
# OneBit(1)
  • AND
LogicalOperator.and_(zero, zero)
# ZeroBit(0)
LogicalOperator.and_(zero, one)
# ZeroBit(0)
LogicalOperator.and_(one, zero)
# ZeroBit(0)
LogicalOperator.and_(one, one)
# OneBit(1)

There is also support to others Logical Gates:
nor_, nand_, xor_andxnor_`

Bytes

There is also a Bytes class.

from bitjoy.dtypes import Bytes

Passing a list of Bit to the Bytes' constructor to creating a bytes instance. NOTE that bytes only have 8 bits. So passing more or less it'll throw an error.

bits = [Bit(0), Bit(0), Bit(0), Bit(0), Bit(1), Bit(1), Bit(0), Bit(0)]
b = Bytes(bits)
# Bytes(0, 0, 0, 0, 1, 1, 0, 0)

To creating a easy bytes, use int_to_bytes function from utils to help.

from bitjoy.utils import int_to_bytes

b1 = int_to_bytes(10)
# Bytes(0, 0, 0, 0, 1, 0, 1, 0)
b2 = int_to_bytes(175)
# Bytes(1, 0, 1, 0, 1, 1, 1, 1)
  • Adding Bytes Bytes class also has support to + operand with __add__ method.
b1_b2 = b1 + b2
# Bytes(1, 0, 1, 1, 1, 0, 0, 1)
  • Casting Bytes supports casting with other number types: int, bin, oct and hex.
int(b1_b2)
# 185

bin(b1_b2)
# '0b10111001'

oct(b1_b2)
# '0o271'

hex(b1_b2)
# '0xb9'

Adders

For arithmetic operators, the class Adder has two method to make additions:
half: to half-adder
full: to full-adder
