On August 22, 2019, the Origins Space Telescope (OST) Study Team delivered the OST Mission Concept Study Report and the OST Technology Development Plan to NASA Headquarters. A key component of this study report includes the technology roadmap for detector readout and how new radio frequency-system-on-chip (RFSoC)-based technology would be used to advance the far-infrared polarimeter instrument concept for a spaceflight mission. We present our current results as they pertain to the implementation of algorithms, hardware, and architecture for instrument signal processing of this proposed observatory using RFSoC technology. We also present a small case study, comparing a more conventional readout system with one based on the RFSoC and show a trade of system complexity versus technology readiness level.
