Unicore Systems 
Short Desc. : IEEE 802.16e (WiMAX) LDPC Encoder IP core
Overview :
Error-correcting coding is an essential tool for enabling reliable
communication. Unicore Systems provide an Intellectual Property
(IP) core for efficient implementation of low-density parity-check
(LDPC) forward error correcting (FEC) encoding schemes intended for the IEEE 802.16e. The IP core covers the entire WiMAX LDPC specification, in terms of block size and code rate. Block size and code rate can be switched on on a block-by-block basis.
Features : - 19 code length supported;
- all ratio 1/2, 2/3A, 2/3B, 3/4A, 3/4B, 5/6 supported;
- on the fly change of code length and code ratio;
- encoded throughput up to 600 Mbit/sec (Virtex-4 -12 speed
- grade).
- Low latency
