Abstract

At the Large Hadron Collider, the vast amount of data from experiments demands not only sophisticated algorithms but also substantial computational power for efficient processing. This paper introduces hardware acceleration as an essential advancement for high-energy physics data analysis, focusing specifically on the application of High-Level Synthesis (HLS) to bridge the gap between complex software algorithms and their hardware implementation. We will explore how HLS facilitates the direct implementation of software algorithms into hardware platforms such as FPGAs, enhancing processing speeds and enabling real-time data analysis. This will be highlighted through the case study of a track-finding algorithm for muon reconstruction with the CMS experiment, demonstrating HLS's role in translating computational tasks into high-speed, low-latency hardware solutions for particle detection and reconstruction. Key techniques in HLS, including parallel processing, pipelining, and memory optimization, will be discussed, illustrating how they contribute to the efficient acceleration of algorithms in high-energy physics. We will also cover design methodologies and iterative processes in HLS to optimize performance and resource utilization, alongside a brief mention of additional techniques like algorithm approximation and hardware / software co-design. In short, this paper will underscore the potential of hardware acceleration in high-energy physics research, emphasizing HLS as a powerful tool for physicists to enhance computational efficiency and foster groundbreaking discoveries.
