------------------------------------------------------------

The International Symposium on Highly Efficient Accelerators and Reconfigurable Technologies (HEART) is a forum to present and discuss new research on computing systems utilizing acceleration technology. The main theme of HEART is achieving high efficiency through accelerators, tailored hardware architectures and new methods for computing systems, which are of utmost importance across a wide spectrum of systems. This includes high-performance computing and data centers, as well as the mobile and IoT space.

Accepted papers will be published in the ACM International Conference
Proceedings Series (ICPS) and will appear in the ACM Digital Library open access:

[ Important Dates and Deadlines ]

Submissions due: March 13, 2026 (AoE)
Notification: April 17th, 2026 (AoE)
Conference Dates: June 17-19, 2026

[ Submission Categories ]
1) Regular Papers:
Prospective authors are invited to submit original contributions as
12-page papers (not counting references) to be considered regular papers.

2) Work in Progress Papers:
Prospective authors are invited to submit an extended abstract of up to 4 pages (not counting references) about an ongoing research project. If the abstract is accepted, the authors will be asked to give an oral presentation. The presentation time may be shorter than that for regular papers.

3) Ph.D. Forum Papers:
Ph.D. students working in areas relevant to HEART are solicited to
submit an extended abstract of up to 4 pages (not counting references)
comprising a summary of their research findings, work in progress, and/or planned research―the Ph.D. Forum is intended as a platform for Ph.D. students to interact with peers and experienced researchers.

Important: The form of Ph.D. forum will consist of pitch and poster
Presentations. The Ph.D. student should be the first author; thesis advisors may be co-authors. The technical program committee will review submissions to ensure quality and relevance. Accepted contributions must be presented at the conference and will require a full registration.

[ HEART 2026 Topics ]
Following its tradition, HEART 2026 will continue to focus on high efficiency as a cross-cutting issue and seeks contributions for the main research track in, but not limited to, the following areas:

Architectures for Efficient Acceleration
- Novel systems/platforms based on FPGA, CGRA, GPU, TPU, Neuromorphic, Quantum, and other devices
- Heterogeneous processor architectures and systems for high-performance and/or low-power
- Domain-specific architectures

Design Methods and Tools for Efficient Acceleration
- Programming paradigms, languages, and frameworks
- High-level synthesis and compilers
- Runtime methodologies for heterogeneous systems
- Design space exploration
- Performance and power modeling; evaluation and analysis
- Benchmarking of heterogeneous and high-performance systems
- New **open-source** tools and frameworks for efficient acceleration

Applications and Systems
- Application examples that benefit from efficient acceleration to a great extent (training/inference, DSP, graph, databases, networking, scientific/HPC, real-time/edge, etc.)
- Complete systems demonstrating increased energy efficiency and/or performance
- Comparisons between accelerator technologies, including trade-offs in programmability, efficiency, and scalability

[ Submission Guidelines - Format and Anonymity ]
HEART 2026 adopts a double-blind review process: authors should **not** identify themselves, so author names, affiliations, e-mail addresses, and self-references should be blanked out.
