LDPC Encoder/Decoder IP Core

Nand Flash write cycles are limited.

Contact Provider Request Datasheet

Overview

Nand Flash write cycles are limited. An ECC detects and corrects failed operations, increasing the lifetime of the Nand Flash memory. For Nand Flash-based data storage, using an ECC is mandatory to ensure data validity. The IPM-LDPC is based on the LDPC algorithm. The  IPM-LDPC Encoder/Decoder is full-featured with multiple parameters to fit your own needs in FPGA and SoC designs.

In fact IPM-LDPC Encoder/Decoder is fully configurable, allowing to it reach the best latency or the smallest footprint.

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.
