Abstract
A decoding device is suitable for a context-based adaptive binary arithmetic coding (CABAC) technique and allows a real-time decoding of high-definition video. The CABAC decoding device allows a simultaneous performing since determination according to multiple conditions is based on logic circuits when the device is formed in hardware. Additionally, when one macro block starts to be decoded, the device reads and stores information about neighboring macro blocks at a time from a memory. Therefore, the device does not need to access the memory at every operation and this improves the overall decoding speed.
