Abstract
The article described a new design of high-speed data transmission, used in BESIII trigger system, with optical fibre that was based on the on-chip serial/deserial transceiver in FPGA. A special custom protocol is defined to transfer the consecutive and real-time data, recover and process the data belongs to the same event at the same time. The design was tested for a long period run. A high level of confidence bit error rate was obtained, and all channels from different transmitters were re-aligned by using unfixed delay alignment method. The design was implemented in the trigger system and would meet the requirements of BESIII.

  • Pretraining has recently greatly promoted the development of natural language processing (NLP)
  • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
  • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
  • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
  • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
