Physical unclonable functions are integrated circuits well-known for their potential to replace dedicated secure storage of cryptographic keys. On FGPAs, ring-oscillators have received great attention as the most preferable implementation. In this work, we present multiple different approaches of measurement control and readout extraction for external storage. Targeting a Zynq-7000 architecture, the final design extracts 3800 · 10000 readouts within 8.04s, which relates to a data extraction rate of 36Mbit/s. In comparison to an early stage design, a reduction in total run time of 98.2% was achieved.
