Tc4200_enc

1) Functional Description

This VCI target corresponds to a IEEE802.16e LDPC encoder. It embeds an internal hardware Cycle Accurate Bit Accurate model of the ​TurboConcept's IEEE802.16e WiMAX LDPC encoder ​tc4200_enc.

TurboConcept's TC4200-WiMAX? Core is the corresponding decoder. It is a high speed Low Density Parity Check code (LDPC) decoder optimized for WiMAX (IEEE 802.16e) specifications. A patented decoding architecture allows meeting high throughputs within small devices, and still offering close-to-ideal Bit Error Rate (BER) performances.

Figure 1 presents the general core structure. The Tc4200_enc is made of a VCI wrapper and an internal hardware decoder model which communicates using proprietary FIFO-like protocols.
