We present two case studies of different architectures for H.264 video decoder. The objective of this case study is to show the design methodology that can maximize the flexibility of video decoder. First, H.264 is designed based on configurable processor. The configurable processor was used to complement the existing functional units with instruction extensions for the H.264 hardware kernel. Secondly,...
High performance microprocessors are designed with general-purpose applications in mind. When it comes to embedded applications, these architectures typically perform control-intensive tasks in a System-on-Chip (SoC) design. But they are significantly inefficient for data-intensive tasks such as video encoding/decoding. Although configurable processors fill this gap by complementing the existing functional...
