    Abstract
    The Level 1 of the PLANCK Low Frequency Instrument (PLANCK/L FI) Data Processing Centre (DPC) is devoted to the handling of scientific and hous ekeeping telemetry. It receives raw telemetry packets from the LFI through a tailored version of the ESA telemetry handling software SCOS 2000, and generates time ordered information of scient ific and housekeeping data to be processed by the subsequent DPC levels. In addition, the Lev l 1 performs live diagnostics on the LFI telemetry. An end-to-end test has been performed recent ly at he LFI integration site (Alcatel Alenia Space, Milan) using the qualification model equipmen t of the on-board Data Acquisition Electronics and Data Processing unit, and its core software . For scientific data, the test is based on the injection of deterministic signals with known proper ties in the acquisition electronics and their comparison with the signal reconstructed from the tel metry data. A regression test has been performed on the housekeeping data by inserting known p arameters values into a set of real housekeeping packets.

    • 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
