Time Predictable CPU and DMA Shared Memory Access
In this paper, we propose a first step towards a time predictable computer architecture for single-chip multiprocessing (CMP). CMP is the actual trend in server and desktop syste...

Static Detection of Livelocks in Ada Multitasking Programs
Abstract. In this paper we present algorithms to statically detect livelocks in Ada multitasking programs. Although the algorithms’ worst-case execution time is exponential, they...

Bus Access Optimization for Predictable Implementation of Real-Time Applications on Multiprocessor Systems-on-Chip
In multiprocessor systems, the traffic on the bus does not solely originate from data transfers due to data dependencies between tasks, but is also affected by memory transfers a...

Decoupling of Computation and Communication with a Communication Assist
Abstract. In an embedded multiprocessor system the minimum throughput and maximum latency of real-time applications are usually derived given the worst-case execution time of the s...

Obstacles in Worst-Case Execution Time Analysis
The analysis of the worst-case execution time (WCET) requires detailed knowledge of the program behavior. In practice it is still not possible to obtain all needed information aut...

CheckerCore: enhancing an FPGA soft core to capture worst-case execution times
Embedded processors have become increasingly complex, resulting in variable execution behavior and reduced timing predictability. On such processors, safe timing specifications e...

Partial Program Admission
Abstract—Real-time systems on non-preemptive platforms require a means of bounding the execution time of programs for admission purposes. Worst-Case Execution Time (WCET) is most...

Predictable Implementation of Real-Time Applications on Multiprocessor Systems-on-Chip
Worst-case execution time (WCET) analysis and, in general, the predictability of real-time applications implemented on multiprocessor systems has been addressed only in very restri...

Automatic scenario detection for improved WCET estimation
Modern embedded applications usually have real-time constraints and they are implemented using heterogeneous multiprocessor systems-on-chip. Dimensioning a system requires accurat...

Optimal static WCET-aware scratchpad allocation of program code
Caches are notorious for their unpredictability. It is difficult or even impossible to predict if a memory access will result in a definite cache hit or miss. This unpredictabilit...
