Project: Job Manager
The Job Manager component is responsible for creating and managing jobs
within the system.
This includes tracking the state of "active" jobs and the retrieval of
stored jobs. Job Manager can be thought of as having several roles,
including a registry of jobs, the scheduling jobs, and providing status of
jobs in the system. Additionally, the Job Manager connects I/O filters
with successive Job Stream interfaces before passing the resultant Job
Stream to the Job.

Project: Electronic Diesel Engine Control software
Engine control Software drives the car by using sensors and actuators. This
software is responsible for coordinating and governing various other
subsystems of the vehicle. The major modules involved are Injections
System, Induction System, Fuel System and Exhaust System. For establishing
communication with other Electronic Control Units in Vehicle CAN protocol
is used. Diagnostics and malfunctioning of the system is also monitored.
This project includes identifying the functionalities and modularizing
them. Each modularized software has to be identified as one task and
scheduled for the execution. The inter-task communication has to be
independent of data reentrancy and data should be synchronized.
The software runs on Motorola Power PC MPC555 micro-controller. ERCOS
(OSEK) multi tasking real time operating system is the RTOS used in this
project. This ERCOS was developed considering the Automobile market where
message transfer rate is very high. ERCOS used a tool called "Off Line Tool
(OLT)" for development, which provides a great feature of modular
development in C.
