Master Thesis Student – Compiler Optimization for RISC-V Processors

Job Title

Master Thesis Student – Compiler Optimization for RISC-V Processors

Role Summary

Join the engineering team in Leuven as a Master's thesis student to analyze microarchitectural features of the RMX7xx, RHX1xx, and RPX1xx RISC-V processor families and develop LLVM compiler enhancements to improve code generation and application performance.

Your work will include performance analysis, benchmarking, and close collaboration with processor architects to validate hardware-software co-optimizations.

Experience Level

Entry-level — position intended for a current Master's student completing a thesis.

Responsibilities

As part of your master's thesis you will:

• Analyze microarchitectural characteristics of the RMX7xx, RHX1xx, and RPX1xx processor families.
• Study processor pipelines, instruction scheduling, instruction fusion opportunities, and multi-issue execution behavior.
• Identify performance bottlenecks and compiler-driven optimization opportunities.
• Design, implement, and validate new optimizations in the LLVM compiler framework.
• Evaluate the impact of compiler enhancements using benchmarking and profiling.
• Collaborate with processor architects and software engineers on hardware-software interactions.
• Document findings and present recommendations for future compiler and processor improvements.

Requirements

Must-have skills and attributes:

• Strong understanding of computer architecture and processor design concepts.
• Knowledge of compiler fundamentals, optimization techniques, and code generation.
• Proficiency in C/C++ programming.
• Familiarity with Linux development environments and common development tools.
• Strong analytical and problem-solving skills; ability to work independently and collaborate with experts.
• Good written and verbal communication skills in English.

Nice-to-have:

• Experience with LLVM or other compiler infrastructures.
• Knowledge of RISC-V architecture and instruction set concepts.
• Understanding of processor microarchitecture, pipelining, and performance optimization.
• Experience with benchmarking, profiling, or performance analysis tools.
• Exposure to embedded systems or low-level software development.

Education Requirements

Currently pursuing a Master's degree in Computer Engineering, Computer Science, Electrical Engineering, or a related technical field (Master's thesis project required).
