Abstract
An embodiment relates to a decoder for decoding CABAC encoded video data in real time for HDTV applications. The decoder comprises a binary arithmetic decoder block for converting an input bit stream into a bin string, a context memory for storing a plurality of context values, and a plurality of finite state machines. Each of the finite state machines is adapted for decoding a particular one of the H.264 syntax elements by providing the binary arithmetic decoder block with an index of the relevant context value within the context memory and by converting the resulting bin stream into a value of the current syntax element. In this manner, a performance of one bin per cycle may be achieved.
