Haitao (Tony) Xia is Distinguished Engineer of R&D at Broadcom Ltd, leading the research and development of advanced read channel and Serdes architectures for data storage systems. Dr. Xia served as Chairman of IEEE Data Storage Technical Committee and President of Chinese American Information Storage Society (CAISS) in the past. Before his work at Broadcom/Avago/LSI, Dr. Xia worked at Silicon Valley start-up, Linked-A-Media Devices, on signal processing and coding in the area of magnetic recording channels and non-volatile memories. Dr. Xia has published more than 20 articles in peer-reviewed journals/conferences, and has more than 120 US patent granted to his name. Dr. Xia is an IEEE Senior Member.
This paper evaluates the performance of several choices of Reed-Solomon code and shows how a frame-interleaved RS(30,26) code can achieve 1e-15 bit-error rate (BER) in the presence of burst errors. See the authors conclude that, as data rates go higher, current 128b/130b encoding is not a good option as the two-bit 01/10 overhead suffers due to its Nyquist pattern property.
PCIe Gen4 enables new wave of innovation to guide inner-loop SerDes optimization assisted by outer-loop system optimization. This paper introduces an outer-layer equalization scheme for managing SerDes inner-layer equalization to optimize overall system-level aggregate performance.
