Abstract
A device includes a memory configured to store image data and an image coding unit implemented in circuitry. The image coding unit is configured to store a first portion of a set of context information in memory of the image coding unit as an array representing a direct access table and store a second portion of the set of context information in a hash table. The image coding unit is further configured to determine whether a context value for context-based coding of a value of an instance of a syntax element for a block of image data is stored in the array or in the hash table, retrieve the context value from either the array or the hash table according to the determination, and context-based code the value of the instance of the syntax element using the context value.
