It was a chance to make improvements and use more powerful state-of-the-art core components. This included a new Arria 10 FPGA and a completely redesigned housekeeping circuit based on an AVR microcontroller. Further, the project was cleaned by removing unused components and features. Main frame conditions stay fixed for backward compatibility, like the mechanical form factor or the 16-bit parallel bus. Majority of gateware and firmware could be reused and just some adaptations for the new FPGA were needed. Nevertheless, providing continuous compatibility with legacy peripherals needed a substantial effort.Geneva : JACoW Publishing 3 pages (2023). doi:10.18429/JACOW-PCAPAC2022-THP15info:eu-repo/semantics/conferenceObjectinfo:eu-repo/semantics/publishedVersionProceedings of the 13th International Workshop on Emerging Technologies and Scientific Facilities Controls, PCaPAC2022, Dolní Brežany, Czech RepublicProceedings of the 13th International Workshop on Emerging Technologies and Scientific Facilities Controls, PCaPAC2022, Dolní Brežany, Czech Republic<br/>13th International Workshop on Emerging Technologies and Scientific Facilities Controls, PCaPAC 2022, Dolní Brežany, Czech Republic, 2022-10-04 - 2022-10-07JACoW Publishing2023info:eu-repo/semantics/openAccessDEhttps://repository.gsi.de/record/358724https://repository.gsi.de/search?p=id:%22GSI-2025-00606%22Researchersinfo:eu-repo/semantics/altIdentifier/doi/10.18429/JACOW-PCAPAC2022-THP15info:eu-repo/semantics/altIdentifier/doi/10.15120/GSI-2025-00606
