Microcontrollers

Microcontroller can be considered as a small size of computer on a chip. Because it consists of processor, random access memory (RAM), read-only memory (ROM) and input/output peripherals. Microcontroller is also named as embedded controllers, since it is part of an embedded system. According to Blacharski (2003) microcontroller defines as “an integrated chip that is often part of an embedded system”. The purpose of develop microcontroller is to evolve the performance and efficiency a machine. Microcontroller can execute itself without the any support from external. Now a day, we can see that there are appliances in everywhere which is developed by microcontroller. For instance, aircraft, vehicle engines, microwaves, fuel injection system, robots, and so on.

For the application of microcontroller, I would like to use vehicle engine as my choice. In recent year, the requirements of customer for a vehicle are making the designer headache no matter on safety, performance, entertainment, or new facilities of a car. Based on the customer required, the new technology of microcontroller has been recommended. For the safety of vehicle, microcontroller is appropriate to provide a new car safety system name fault-tolerant system instead of antilock braking system. According to Bannatyne (2009) not only the electrical fault can be recognized by the fault-tolerant system, but the existing known fault must be worked safely. In the fault-tolerant system, which classifies CPU as two categories, there are main CPU and redundant CPU. The main CPU in charge of testing the whole fault-tolerant system and the redundant CPU is using to verify the stability of the first CPU once the first CPU is getting unstable.

...ncy chip able to solve the problems that previously the electromagnetic compatibility (EMC) was unable to solve it which are high electromagnetic discharge and corruption of radio frequency. After that, microcontroller is able to save the power of being used during the operation of electronic control unit (ECU). And the last advantage is the operation and the memory content of the car safety system gets a guarantee. The operation would not fail and the stability of memory content is getting enhanced under supervise of microcontroller. So, this is all about the advantages of using microcontroller in the vehicle engine.
