Abstract

NISP is the near IR spectrophotometer instrument part of the Cosmic Vision Euclid mission. In this paper we describe an end-to-end simulation scheme developed in the framework of the NISP design study to cover the expected focal-plane on-board pre-processing operations. Non-destructive detector readouts are simulated for a number of different readout strategies, taking into account scientific and calibration observations; resulting frames are passed through a series of steps emulating the foreseen on-board pipeline, then compressed to give the final result. In order to verify final frame quality and resulting computational and memory load, we tested this architecture on a number of hardware platforms similar to those possible for the final NISP computing unit. Here we give the results of the latest tests. This paper mainly reports the technical status at the end of the Definition Phase and it is presented on behalf of the Euclid Consortium.
