Summary

The course studies techniques to exploit Instruction-Level Parallelism (ILP) statically and dynamically. It also addresses some aspects of the design of domain-specific accelerators. Finally, it explores security challenges based on microarchitectural features and hardware isolation techniques.

Content

Pushing processor performance to its limits:

• Principles of Instruction Level Parallelism (ILP)
• Register renaming techniques
• Prediction and speculation
• Simultaneous multithreading
• Optimized memory hierarchies and efficient virtualization
• VLIW and compiler techniques for ILP
• Dynamic binary translation

Domain specific architectures and accelerators:

• Specificities of embedded vs. general computing processors
• Overview of DSPs and related compilation challenges
• Basic notions of High-Level Synthesis
• Statically and dynamically scheduled accelerators

Security concerns:

• Information leakage through the memory hierarchy
• Information leakage through the front-end (branch prediction)
• Hardware-based architectures for isolation (e.g., ARM TrustZone and Intel SGX)
• Power-analysis side-channel attacks

Keywords

Processors, Instruction Level Parallelism, Systems-on-Chip, Embedded Systems, High-Level Synthesis, Hardware Security.
