Abstract(in English) | DCT is used for a picture or sound extension technology to realize by the system LSI dealing with video signals. Generally, the dedicated processors are needed to process DCT or any other video/audio signals, such as a DSP. However, if a DSP is adopted as a processing element, hardware cost will increase very much. Then, suppressing the increase in hardware cost is necessary as much as possible, and moreover optimizing the structure of a processor is required for high-speed processing. In this research, performance of multiple-accumulate operation and Σ-operation were raised by implementing a major part of DCT as hardware. Speed and hardware cost is compared with respected to conventional multiple-accumulate hardware and Σ-operation machine with a normal processor and a processor-added DCT block. It was shown that the operation speed is 40% faster than normal processor. The cost is 48% lower for the multiple-accumulate hardware and 46% lower for the Σ-operation than processor added the DCT block. |
