[Turbo Concept]

Introducing turbo product codes with BCH “t=2” codes Customisable bitrate : 7 to 25 Mbits/s

Turbo codes improves a transmission link by an additional gain of 2 to 3 decibels, compared to classical FEC solutions.

TC3000 is a family of IP Cores offering powerful and flexible turbo product codes. TC3000 is

the first IP Core implementing Hamming and double-error-correcting BCH product codes. A

highly generic approach allows TC3000 to be precisely optimised for a target application.

Features

• Very High FEC performance : Hamming and BCH-t=2 codes

• Bitrate customisable : 7 to 25 Mbits/s typical @ 5 iterations

• Large block sizes : up to 65 kbits

• On-the-fly change of the code

• Shortening facilities to adjust packet size and coding rate

• Single-chip PLD IP Core : Altera APEX, no external memory required

• Latency reduction by bank-swapping

• Two selectable configuration interface
