Modelling Adaptive Systems in ForSyDe

Ingo Sander, Axel Jantsch
2008 Electronical Notes in Theoretical Computer Science  
Since ForSyDe is based on the functional paradigm we can model adaptivity by using functions as signal values, which we use as the base for our concept of adaptive processes.  ...  Depending on the level of adaptivity we categorise four classes of adaptive process, spanning from parameter adaptive to interface adaptive process.  ...  0 i[k − 1] k > 0 Modelling of Adaptivity We extend the ForSyDe framework to model adaptivity on several levels of abstraction.  ...

Dongwook Lee, Hyungman Park, Andreas Gerstlauer
2012 Proceedings of the eighth IEEE/ACM/IFIP international conference on Hardware/software codesign and system synthesis - CODES+ISSS '12  
Addressing ever-increasing complexity and heterogeneity of Multi-Processor Systems-on-Chip (MPSoCs), Transaction-Level Models (TLMs) have emerged to raise the design abstraction to higher levels [3] .  ...  Even with transaction-level modeling and high-level synthesis of hardware, communication interfaces still have to be manually designed at a low protocol level.  ...  Hardware Synthesis Flow Our flow supports hardware synthesis from models at varying levels of abstraction (Fig. 2) .  ...

Achieving Smooth Component Integration with Generative Aspects and Component Adaptation [chapter]

Yankui Feng, Xiaodong Liu, Jon Kerridge
2006 Lecture Notes in Computer Science  
An expandable library of reusable adaptation aspects at multiple abstraction levels has been developed. A prototype tool is developed to scale up the approach.  ...  Although component adaptation has acted as a key solution of eliminating these mismatches, existing practices are either only capable for adaptation at a rather simple level, or requires too much intervention  ...  Using this model, an aspect is described as a set of abstract join points which are used when an aspect is combined with the base-modules of a software system.  ...
