Emerging, high-speed bus technologies and migration to multi-core platform requires detailed high-level system analysis before scheduling implementation. Systems engineers run multi-variant workloads to conduct a battery of trade-offs including task response time vs. power dissipated; distributed vs. centralized processing; and throughput vs. cost. Analytical means and over-provisioning cannot handle the system complexity required to identify […]

Real-time constraints, reconfigurability and safety have a direct impact on architecture design and on the validation/certification process, at the aircraft and system level. Current certification of Integrated Modular Architecture (IMA) avionics using network calculus cannot accurately predict communication and processing latency. Here is a solution for IMA-based avionics to generate certification tests, conduct what-if analysis, […]

Incremental Designs are common and highly practiced approach in every avionics system design process. Designing a new system from ground-up is prone to multiple issues right from technical to overall cost required. Even a minor up gradation of application software may cause huge impact on the overall system performance and power consumption. Predicting system performance […]
