VESA DisplayPort 1.4 Forward Error Correction (FEC) Transmitter

Overview

The DisplayPort Forward Error Correction (FEC) Transmitter IP core implements Reed-Solomon FEC and symbol interleaving as specified by the VESA DisplayPort 1.4 specification. Forward Error Correction is required to ensure glitch-free Display Stream Compression (DSC) bitstream transport.

Key Features

VESA DisplayPort 1.4 compliant
Reed-Solomon (254,250) FEC, 10-bit symbols
Two-way interleaving for 1-, 2-, and 4-lane modes (4-lane mode requires 2 FEC IP core instances)
Optionally includes the DisplayPort main 8b/10b encoder
Status and control can be done with signals or optionally via an
integrated APB register interface module
Single unified APB interface supports 4-lane mode
