“…As described in Corcione et al, 8 there are three possible read-out schemes implemented by the DPU. In the Multiaccumulation mode, a non destructive sequence of frames is taken where only some selected frames are read out, organized into several groups, and a linear fit is performed on the average of these groups.…”

In this paper we describe the main requirements driving the development of the Application software of the ICU of NISP, the Near-Infrared Spectro-Photometer of the Euclid mission. This software will be based on a real-time operating system and will interface with all the subunits of NISP, as well as the CMDU of the spacecraft for the Telecommand and Housekeeping management. We briefly detail the services (following the PUS standard) that will be made available, and also possible commonalities in the approach with the ASW of the VIS CDPU, which could make the development effort more efficient; this approach could also make easier the maintenance of the SW during the mission. The development plan of the ASW and the next milestones foreseen are described, together with the architectural design approach and the development environment we are setting up.

The Atmospheric Remote-sensing Infrared Exoplanet Large-survey mission (ARIEL) [1] is one of the three present candidates for the ESA M4 (the fourth medium mission) launch opportunity. The proposed Payload [2], [3], [4] will perform a large unbiased spectroscopic survey from space concerning the nature of exoplanets atmospheres and their interiors to determine the key factors affecting the formation and evolution of planetary systems.ARIEL will observe a large number (> 500) of warm and hot transiting gas giants, Neptunes and super-Earths around a wide range of host star types, targeting planets hotter than 600 K to take advantage of their well-mixed atmospheres. It will exploit primary and secondary transits spectroscopy in the 1.2 − 8 µm spectral range and broad-band photometry in the optical and Near IR (NIR).The main instrument of the ARIEL Payload is the IR Spectrometer (AIRS) [5] providing low-resolution spectroscopy in two IR channels: Channel 0 (CH 0 ) for the 1.95 − 3.90 µm band and Channel 1 (CH 1 ) for the 3.90 − 7.80 µm range. It is located at the intermediate focal plane of the telescope [6], [7], [8] and common optical system and it hosts two IR sensors and two cold front-end electronics (CFEE) for detectors readout, a well defined process calibrated for the selected target brightness and driven by the Payload's Instrument Control Unit (ICU).
