APEIRON: composing smart TDAQ systems for high energy physics experiments

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.
