Model Overview

Purpose of this model is to conduct performance analysis of Jet engine control system. Primary requirements of the simulation model is to capture end to end latency for Throttle control signals, impact of throttle control signals on the engine task processing, distribution of tasks between multi-core PowerPC Processing platform, instantaneous and average power consumption of the complete system. These analysis helps the designer to assure that the selected processing platform is capable of processing both engine and throttle control tasks without exceeding power and performance requirements.

The simulation model has 3 cords, IO Cord, Processor Cord and Power Cord. IO cord has interfaces to the RPM sensor, Air Speed Sensor, temperature sensor and Throttle PWM sensor. Processor Cord has 2 PowerPC Processor modules, memory and interconnects. ARINC 653 is modeled to perform time and space partition. We have considered 3 partitions and the tasks can be sceduled to run on different partitions.
