Hamid Farzaneh received his bachelor's degree in Computer Engineering from Shiraz University in August 2019, and his master's degree in Computer Systems and Architecture from Shahid Beheshti University in November 2021.
In August 2022, he joined the chair as a research assistant. He works on high-level compiler frameworks (like MLIR) and optimization for data and computation mapping onto highly heterogeneous systems with mainstream CPUs, FPGAs, SRAM, DRAM, and emerging NVMs and accelerators.
The volume of data processing in these applications has skyrocketed in recent years and demands significantly higher off-chip memory bandwidth. However, increasing the off-chip bandwidth is becoming increasingly expensive and is strictly constrained by the chip package and system models. To overcome the memory wall and capacity and power walls, computer architects are moving to non-Von-Neumann system models like near-memory and in-memory computing. However, The programmability aspect of these systems has received relatively less attention. Using the power of compilers, I tackle issues in high performance, energy efficiency, and hardware/software cooperation of these systems.
In that regard, my current main topics are:
- Working on high-level compiler frameworks (like MLIR) and optimizing data and computation mapping for data and computation mapping onto heterogeneous systems
- Developing models for managing workloads in heterogeneous systems
Possible student topics include:
- Front-ends for MLIR Computing-in-Memory(CIM) Compiler
End-to-end compilation flows for CIM-capable systems exist, but interfaces to high-level languages are missing (limited). The goal of this project is to design and implement front-ends to enable lowering high-level languages/descriptions to the CIM compilers.
- Heterogeneous Systems: Mapping and Optimizations
Also, if you have a related topic in mind, please feel free to reach out.

Abstract
This paper explores the challenges and opportunities of integrating non-volatile memories (NVMs) into embedded systems for machine learning. NVMs offer advantages such as increased memory density, lower power consumption, non-volatility, and compute-in- memory capabilities. The paper focuses on integrating NVMs into embedded systems, particularly in intermittent computing, where systems operate during periods of available energy. NVM technologies bring persistence closer to the CPU core, enabling efficient designs for energy-constrained scenarios. Next, computation in resistive NVMs is explored, highlighting its potential for accelerating machine learning algorithms. However, challenges related to reliability and device non-idealities need to be addressed. The paper also discusses memory-centric machine learning, leveraging NVMs to overcome the memory wall challenge. By optimizing memory layouts and utilizing probabilistic decision tree execution and neural network sparsity, NVM-based systems can improve cache behavior and reduce unnecessary computations. In conclusion, the paper emphasizes the need for further research and optimization for the widespread adoption of NVMs in embedded systems presenting relevant challenges, especially for machine learning applications.
