Hard Real-Time Delay (RTD) Estimation and Analysis for Safety-Critical System

Avionics embedded systems encapsulate the greater number of processing units that are completely under its control and with respect to the functional requirement very often they have strict timing analysis. The purpose of this work is to capture the timing analysis of the system-level data transfer using the AFDX format sending to the Multi-functional display computer, which has an IMA architecture. In the most recent years due to the strong partition of integrated modular avionics (IMA) architecture, they have been widely adopted in the field of avionics. In the development of avionics systems, although the architecture of IMA can achieve an effective reduction in cost and enhancement in reliability it results in less scheduling difficulty. So, even under the worst-case situations the deadlines of the IMA system should be meet and evaluation of the latency period has to obtain. The methodology involved for timing analysis is presented based on the case study carried out using visualsim simulation platform.
