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