It presents the design methodology, high-level architectural overview, architecture and design of each of the processing element of the SIR PF. It also includes the traceability matrix from software component to the requirements. This document covers the functional architecture of SIR PF; although it does not generally address algorithm implementation issues or explain scientific code, references to the relevant documents are included. This document explains what the software does and how, but it does not explain how to operate it, for that refer to the Software User Manual.ELETTRONICOenResearch reportFIS/05 - ASTRONOMIA E ASTROFISICAERC sectors::Physical Sciences and Engineering::PE9 Universe sciences: astro-physics/chemistry/biology; solar systems; stellar, galactic and extragalactic astronomy, planetary systems, cosmology, space science, instrumentation::PE9_17 Instrumentation – telescopes, detectors and techniques
