Overview

This is a Reed Solomon decoder capable of operating with shortened codewords. The basic mother rate is (N,K) = (255,239) which has 16 parity bytes and can correct up to 8 corrupted bytes (up to 8 bits in a byte can be in error). The mother rate can be shortened to N_MAX <= 255 but still retains the ability to correct up to 8 bytes in error. The decoder only outputs K bytes per N bytes in, and these are in natural order. It has enough memory to operate continuously with one byte per clock cycle on its input, leading to a net rate of 8*CLK bps of coded data. The codeword length is programmable at run-time.

Practical Considerations of LDPC Decoder Design in Communications Systems

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.

Audio Transport in DisplayPort VIP

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.
