1 MAST: A Timing Behavior Model for Embedded Systems Design Processes By: Michael González Harbour, José Javier Gutiérrez, José Carlos Palencia, José María Drake, Julio Medina, Patricia López Universidad de Cantabria, Spain ARTIST workshop on Models of Computation and Communication MoCC, Zurich, November 2006 GRUPO DE COMPUTADORES Y TIEMPO REAL Michael González Harbour 1

2 1. Introduction: Background Many real-time systems are now distributed Cyclic executives being replaced by run-time schedulers Fixed priority and EDF scheduling are most popular among the run-time scheduling policies Schedulability analysis techniques have evolved a lot in the last decade Originally RM and DM priority assignment techniques, together with response-time analysis Extended to distributed systems (holistic analysis, HOPA) Offset-based analysis introduced (FP and EDF) Multiple-event synchronization handled GRUPO DE COMPUTADORES Y TIEMPO REAL Michael González Harbour 2

3 Motivation The latest schedulability analysis techniques are difficult to apply by hand Need for a rich and flexible model of the real-time system: distributed, multiprocessor, or single processor composable software modules separation of architecture, platform, and software modules rich set of event-driven patterns; e.g.: e 1 t 1 m 2 t 5 e 7 + t 7 m 8 t 3 m 4 + t 6 GRUPO DE COMPUTADORES Y TIEMPO REAL Michael González Harbour 3

4 Objectives Develop a model for describing the timing behavior of eventdriven distributed real-time systems Open model that may evolve to include new characteristics or points of view of the system Develop a set of tools for analyzing the timing behavior of the application: - Schedulability analysis (hard real-time requirements) - Synchronization blocking calculation - Discrete-event simulation (soft real-time) - Priority assignment - Sensitivity analysis GRUPO DE COMPUTADORES Y TIEMPO REAL Michael González Harbour 4

18 4. Integration into the design process Components built with their own timing behavior model passive components: operations and shared resources active components: single or multithreaded, distributed,... The model is parameterized i.e., actual data for WCETS Deployment tool instantiates the parameterized component models provides the platform model integrates them with the real time situation model Automatic schedulability analysis is then made GRUPO DE COMPUTADORES Y TIEMPO REAL Michael González Harbour 18

19 Integration into the design process Architectural real-time models Scheduling policies WCET evaluation Translation Design Detailed Design Mechanism Design Coding Architectural Design Unit Testing Concurrency patterns Synchronization patterns Generation of detailed realtime models Object analysis Integration and Test Testing Validation System Engineering Party Requirements Analysis Analysis Mapping real-time properties to subsystems High-level real-time analysis Schedulability analysis Priority Assignment Sensitivity analysis Identification of realtime situations: - Transactions - Timing requirements - Work loads GRUPO DE COMPUTADORES Y TIEMPO REAL Michael González Harbour 19

21 6. Conclusions MAST defines a model for describing real-time systems distributed and multiprocessor complex synchronization and event-driven schemes composable software modules independence of architecture, platform and modules MAST provides an open set of tools hard and soft real-time analysis automatic blocking times, priority assignment, sensitivity analysis... XML specification language allows easy integration with other tools (i.e., UML tools) GRUPO DE COMPUTADORES Y TIEMPO REAL Michael González Harbour 21
