Designing Hard Real-time Systems
- in Ada: Moving Towards 2000, Proceedings of the 11th Ada-Europe Conference, Lecture Notes in Computer Science Vol 603, Springer-Verlag
, 1992
"... This paper presents a systems life cycle and a structured design method which are tailored towards the construction of real-time systems in general, and hard real-time systems in particular. The standard systems life cycle is modified to take into account the expression and satisfaction of non-funct ..."

Flexibility in Statically Scheduled Hard Real-Time Systems
, 1994
"... Static scheduling has been shown to be appropriate for a variety of hard real-time systems, mainly due to the verifiable timing behavior of the system and the complex task models supported. ..."

Multi-Criteria Optimization of Hard Real-Time Systems
"... Modern embedded hard real-time systems often have to com-ply with several design constraints. On the one hand, the system’s execution time has to be provably less than or equal to a given deadline. On the other hand, further constraints may be given with regard to maximum code size and en-ergy consu ..."

Language Constructs and Transformation for Hard Real-time Systems
- Proc. of ACM SIGPLAN Workshop on Languages, Compilers and Tools for Real-Time Systems, La Jolla
, 1995
"... In practice, time critical portions of hard real-time systems are still implemented in low-level programming languages and manually tuned to meet all the timing requirements. Without a real-time language that supports an appropriate way of specifying timing constraints for a generic hard real-time s ..."

Integrating Multimedia Applications in Hard Real-Time Systems
- in Proc. 19th IEEE Real-Time Systems Symposium (RTSS’98
, 1998
"... This paper focuses on the problem of providing efficient run-time support to multimedia applications in a real-time system, where two types of tasks can coexist simultaneously: multimedia soft real-time tasks and hard real-time tasks. Hard tasks are guaranteed based on worst case execution times and ..."

Collection for Hard Real-Time Systems *
, 1992
"... Hardware-assisted garbage collection combines the potential of high average-case alloca-tion rates and memory bandwidth with fast worst-case allocation, fetch, and store times. This paper describes an architecture that allows memory fetch and store operations to execute, on the av erage, nearly as f ..."

as fast as traditional memory. Support for caching garbage-collected memory cells and a protocol designed to minimize communication between the CPU’s cache and memory allow the system to deliver very high performance. The architecture is real-time in that the worst-case time required for a memory fetch

Reliability models for hard real-time systems

"... We present a new reliability model for hard real-time systems. This is an extended Markov model, derived from an analysis of the generic properties of hard real-time systems subject to a simple random-fault model. Our model permits analysis of the run-time behaviour of a system, in order to derive t ..."
