APEIRON: composing smart TDAQ systems for high energy physics experiments
This work addresses the need for efficient, programmable TDAQ systems in high energy physics experiments, but the results are preliminary and lack quantitative performance comparisons.
APEIRON introduces a distributed heterogeneous processing framework for multi-FPGA systems tailored to smart TDAQ in high energy physics, demonstrated through a particle identification application for the NA62 experiment.
We present APEIRON, a distributed heterogeneous processing framework comprising both hardware architecture and software stack for multi-FPGA systems. Targeting smart trigger and data acquisition (TDAQ) systems in high energy physics, APEIRON spans the full software hierarchy: from low-level device drivers to a high-level dataflow programming model based on High-Level Synthesis. We describe the framework design, its core communication infrastructure, and a particle identification application for the NA62 experiment as a representative physics use case.
