bitsy

This project provides a Python library to access/modify a numpy array bit-wise, like a stream of bits which can be accessed in FIFO manner only.

Getting Started

Prerequisites

The prerequisites are :

• Python 3 (or more)
• Numpy

You can download python from here. And to install numpy run the following command in command prompt.

pip intall numpy

Installing

To install the package on your machine use the following command.

pip install bitsy

Examples

To use the library you need to import it. And then you can declare an empty bitstream object or instantiate it with a numpy array.

import numpy 
import bitsy 

The numpy array used must be of dtype = 'uint8'/ 'uint16'/ 'uint32'.

arr = numpy.array([255,5,31], dtype='uint8')

Declare the bit streams.

bs = bitsy.bitstream(arr) #bitstream initialized with arr
bs2 = bitsy.bitstream() #empty bitstream

Print the bit streams.

bs.show()

Output :

0b11111111
0b101
0b11111

Read from bitstream and write in other.

five_bits = bs.read(5)
print(bin(five_bits))
bs2.write(5,five_bits)

Output :

0b11111

Now the bit streams are :

bs.show()
print(" ")
bs2.show()

Output:

0b111
0b101
0b11111

0b11111
