Systems and methods for coding

A system for coding, comprising:

• at least one storage medium including a set of instructions;
• and
• at least one processor in communication with the at least one storage medium, wherein when executing the set of instructions, the at least one processor is directed to cause the system to:
• receive at least two contexts including a first context and a second context;
• for each of the at least two contexts,
• obtain, from at least one lookup table, at least one coding parameter corresponding to the context;
• determine a probability interval value corresponding to the context based on a previous probability interval value and the at least one coding parameter;
• determine a normalized probability interval value corresponding to the context by performing a normalization operation on the probability interval value;
• determine a probability interval lower limit corresponding to the context based on a previous probability interval lower limit and the at least one coding parameter;
• determine a normalized probability interval lower limit corresponding to the context by at least performing the normalization operation on the probability interval lower limit;
• and
• output at least one byte corresponding to the context based on the normalized probability interval lower limit.
