Variable length coding (VLC) is widely used in the entropy codec part of various video codec standards. Its parallelism is difficult to be developed due to its inherent bit-serial characteristic. As it becomes the system bottleneck of real-time video decoding, this paper presents a bitstream co-processor which greatly accelerates the codec of VLC by(More)
A delay slot scheduling framework for VLIW architectures is presented in this paper. In this framework, an assembly data dependence graph is proposed to describe the data dependences among instructions in a basic block. An assembly control flow graph is also proposed to describe control relations among basic blocks. With the help of predicate analysis(More)
How to design a practical, low-cost voice signal processing system has been paid more attention since voice signal processing plays a significant role for information exchange in our highly developed information society. The paper firstly introduces the function block diagram of the voice signal processing system and its processing method; then expatiates(More)
