Overview
The TurboConcept TC3400 is an iterative decoder of Turbo Product Codes (TPC). TPC is an attractive, advanced forward error correction (FEC) technique offering optimization for low implementation cost or very high throughput.
The TC3400 supports two-dimensional TPC codes, built using parity codes or Hamming codes. Optional support for high-performance Bose-Chaudhuri-Hocquenghem (BCH) codes (double-error correcting BCH family) is also available. The maximum code length and the optional BCH code support are chosen up-front as parameter options before core generation. This enables optimized core resource usage.
Two distinct throughput profiles are available:
-
Single decoder engine, TC3401, offering 40–50 coded Mbps on low-cost devices (Cyclone® series)
-
Four decoder engines, TC3404, offering 300+ coded Mbps on high-performance devices (Stratix® series)
A corresponding TPC encoder is available. Please contact TurboConcept for more details.
