ABSTRACT: This paper proposes a solution for back-to-back 200+ MHz 150-channel data acquisition based on Xilinxs Zynq-7000 family (dual-core ARM + Artix-class FPGA) with Linux Ubuntu rootfs and PYNQ software framework and application running in Jupyter notebook. A comparison is made between High Level Synthesis (HLS) and Hardware Description Language (HDL) versions of the device (performance, power consumption). It distinguishes itself from the state of art by providing a very good (MSa/s * channel) / USD value, in addition to large amounts of sample storage.KEYWORDS: SoC, FPGA, HLS, HDL, many channels, logic analyzerRead full text (pdf)
