Projects

ParPerOS: Parallel Persistency OS (DFG: LO 1719/8-1 and DI 2840/2-1)

In ParPerOS, we examine new abstractions for unified but efficient and optionally crash-consistent low-level memory management for data objects in heterogeneous memory systems that consist of volatile, persistent, distributed and other types of main memory.

Primitives and Abstractions for Self-Contained Virtual-Memory Areas in the Linux kernel

Implement the basic abstraction for self-contained virtual-address-space areas in Linux, by which we want to ease the allocation, the sharing, and the management of huge amounts of memory. [PDF]

How to trust the Snake: Extending the Chain of Trust to Interpreted Languages on Highly Embedded Systems

Extend Micropython so, that it can decide whether or not the code was put in place by the developer, not a hacker. Also the integrity of the code needs to be proven during execution.
