This optimized silicon IP core is designed for IEEE 802.11 n/ac/ax/be (WiFi 4/5/6/7) compliant low-density parity-check (LDPC) decoding, addressing the growing demand for ultra-high-throughput solutions in WiFi transceiver chips with a minimal area footprint. The IP core can meet the stringent 30 Gbps throughput requirements of the latest WiFi 7 (IEEE 802.11be) standard. A cross-layer optimization of algorithm, architecture, and circuit has resulted in the best-reported power, performance, and area results for a WiFi-compliant LDPC decoder. Key features of the IP are:
1. Fully compliant with IEEE 802.11n/ac/ax/be (WiFi 4/5/6/7),
2. Achieves the best-reported power, performance, and area results,
3. Implements layered LDPC decoding for faster convergence,
4. Supports all WiFi code rates; 1/2, 2/3, 3/4, 5/6,
5. Supports all WiFi frame lengths: 648, 1296, 1944,
6. Has configurable max-iterations input.
