Overview
Reed-Solomon Encoder and Decoder are commonly used in data transmission and storage applications, such as broadcast equipment, wireless LANs, cable modems, xDSL, satellite communications, microwave networks, and digital TV. The Reed-Solomon Decoder LogiCORE module is a high speed, compact design that implements many different Reed-Solomon coding standards including G.709, DVB, ATSC, IEES and CCSDS. The core is fully synchronous, using a single clock, and supports continuous input data with no gap between code blocks. The core is parameterizable, allowing designers to control the symbol size, the code block length, the number of errors corrected, and the control signal behavior. This Decoder supports both error and erasure decoding. It supports any primitive field polynomial for a given symbol size. The core also counts the number of errors corrected and flags any failures.

This paper covers some practical aspects of designing the LDPC decoder starting from comparison between different techniques, different decoders parameters or standards, the effect of those parameters on the LDPC performance, also it discusses the algorithm selection process, and floating point implementation process.
We describe our SoC implementation of a baseband subsystem for a high performance 4G terminal. Our architecture, called FAUST, is based on distributed synchronization and asynchronous communication. We highlight how we have actually implemented these two

DisplayPort uses Secondary Data Packets (SDPs), which are transported over the Main-Link that are not main video stream data. This allows it to carry audio and video simultaneously. The VIP supports audio transmission both in the original mode as defined in the specification as well as just as any other SDP being transmitted.
In this paper, a typical research case will be described on how to extend an existing SoC architecture of baseband processor on 3G terminal to the player on network multimedia compressed with MPEG-4, especially on how to build an effectively multi-layer a
