The design of a single-chip multichannel video decoder

Abstract

An analog video decoder is a complicated SOC (system-on-chip) with both analog and digital circuits on it, while a multichannel video decoder will have several decoders integrated on the same chip. In this paper, we talk about the design of a four-channel video decoder. We address the common issues met in the SOC design, and how we handle them in this design. The paper covers different kinds of blocks: analog, phase-locked loop (PLL), digital data-path, and microprocessor etc.
