Business logic imp in LMAX architecture in python

Question

I am trying to implement disruptor in Lmax architecture . As you know in lmax architecture we have a ring buffer for creating a queue to process data . Here you can see the structure of that :

I have implemented this structure in python as you can see here :

    import multiprocessing




class CircularBuffer(object):

    def __init__(self, max_size=10):
        """Initialize the CircularBuffer with a max_size if set, otherwise
        max_size will elementsdefault to 10"""
        self.buffer = [None] * max_size
        self.blconsumer = 0
        self.receiver = 0
        self.journalerPointer=0
        self.replicatorPointer=0
        self.unmarshallerPointer=0
        self.max_size = max_size

    def __str__(self):
        """Return a formatted string representation of this CircularBuffer."""
        items = ['{!r}'.format(item) for item in self.buffer]
        return '[' + ', '.join(items) + ']'

    def size(self):
        """Return the size of the CircularBuffer
        Runtime: O(1) Space: O(1)"""
        if self.receiver >= self.blconsumer:

        # if self.is_empty():

    def unmarshaller(self):

            self.unmarshallerPointer = (self.unmarshallerPointer + 1) % self.max_size
            return item   
    

As you can see in the picture we have a business logic part in Lmax that fetches data from Ring Buffer into CPU for fast processing . Unfortunately I couldn't find any document to implement Business logic layer . How can I fetch data from ring buffer into cpu register in Lmax with python ?
