Distributed Waveform Generation and Digitization System Based on Transparent Transmission

Distributed Waveform Generation and Digitization System Based on Transparent Transmission

中文摘要英文摘要

Waveform generation and digitization play essential roles in numerous physics experiments. In traditional distributed systems for large-scale experiments, each front-end node contains an FPGA for data pre-processing, which interfaces with various of data converters and exchanges data with a back-end central processor. However, streaming readout architecture has become the new paradigm for many experiments, benifits from the advance- ments in data transmission and computing technologies. This paper proposes a scalable distributed waveform generation and digitization system that utilizes fiber optical connections for data transmission between front-end nodes and the central processor. By utilizing transparent transmission on top of the data link layer, the clock and data ports of the converters in front-end nodes are directly mapped to the FPGA firmware in the back-end. This streaming readout architecture reduces the complexity of front-end development and keeps the data conversion close to the detector. Each front-end node uses a local clock for waveform digitization. To translate the tim- ing information of events in each channel into the system clock domain within the back-end central processing FPGA, a novel method is proposed and evaluated using the demonstrator system.
