The X-ray Observatory ATHENA was proposed in April 2014 as the mission to implement the science theme ""The Hot and Energetic Universe"" selected by ESA for L2 (the second Large-class mission in ESA’s Cosmic Vision science programme). One of the two X-ray detectors designed to be onboard ATHENA is X-IFU, a cryogenic microcalorimeter based on Transition Edge Sensor (TES) technology that will provide spatially resolved high-resolution spectroscopy. X-IFU will be developed by an international consortium led by IRAP (PI), SRON (co-PI) and IAPS/INAF (co-PI) and involving ESA Member States, Japan and the United States. We present here a software prototype package (SIRENA) in development as an anticipated contribution of IFCA/Spain to X-IFU through the Digital Readout Electronics (DRE) unit, in particular in the Event Processor Subsytem. SIRENA consists of a set of on board processing algorithms aimed to recognize, from a noisy signal, the intensity pulses generated by the absorption of the X-ray photons, to lately reconstruct their energy, position and arrival time. The current status of the package (integrated in the X-IFU endo-to-end simulator SIXTE), regarding the algorithms trade-offs and different triggering techniques under study will be discussed in this poster.
