A semantic-based model-driven software design method for embedded real-time control system is proposed in this paper. The graphic model and semantic model of main objects are abstracted from popular real-time operating systems. An object-related behavior modeling and sorting method is presented for effective interactive between object models. A real-time data acquisition and display application designed...
Data allocation of on-chip scratch-pad memory is a key problem for the performance of embedded system employing SPM as on-chip data memory. Based on the solution to knapsack problem, we propose its knapsack model then employ dynamic planning method to give its optimal algorithm with the complexity of O(nC). Experiment results show that the method proposed in this paper can obtain the optimal result...
Many uncoordinated tasks often run in the same time in embedded wireless network, In this paper, we studied a task-sharing Optimization mechanism which is based on event semantics; discussed the definition, management and scheduling of the share structure on the bases of actor-oriented design method; described the event semantics system and signal types; at last given an example of multi-task Optimization...
Conventional event-triggered architecture (ETA) can not meet the industry hard R-T control requirements in security field. This paper studies a hard R-T control embedded control software design mode based on TTA; discusses the task scheduling principle and mode switching method which are based on TTA; and give a series of concrete formalized description and the sequence chart of execution.
