In this paper, we propose an optimized real-time MPEG-2 video decoder. The decoder has been implemented in one FPGA device as a HW/SW partitioned system. We made time/power-consumption analysis and optimization of the MPEG-2 decoder. On the basis of the achieved results, we decided for HW implementation of the IDCT and VLD algorithms. Remaining parts were realized in SW with 32-bit RISC processor. MPEG-2 decoder (RISC processor, IDCT core, VLD core) has been described in Verilog/VHDL and implemented in Virtex…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
