VLSI Implementation of a VC-1 Main Profile Decoder for HD Video Applications

Abstract

SUMMARYIn this paper, we present a high-performance VC-1 mainprofile decoder for high-definition (HD) video applications, which can decode HD 720p video streams with 30 fps at 80 MHz. We implemented the decoder with a one-poly eight-metal 0.13 µm CMOS process, which contains about 261,900 logic gates and on-chip memories of 13.9 KB SRAM and 13.1 KB ROM and occupies an area of about 5.1 mm 2 . In designing the VC-1 decoder, we used a template-based SoC design flow, with which we performed the design space exploration of the decoder by trying various configurations of communication channels. Moreover, we also describe architectures of the computation blocks optimized to satisfy the requirements of VC-1 HD applications. key words: SMPTE 421M-2006 VC-1, video decoder, transaction level modeling, design space exploration
