General Purpose Computer | Embedded Systems |
---|---|
It is designed using a microprocessor as the main processing unit. | It is mostly designed using a microcontroller as the main processing unit. |
It contains a large memory semiconductor memories like cache and RAM. it also contains secondary storage like hard disks etc. | It uses semiconductor memories,but does not require secondary memories like hard disk,CD.lt sometime has special memory called flash memory. |
It is designed such that it can cater to multiple tasks as per requirement. | It is designed such that it can cater to a particular predefined task. |
It is mostly costlier compared to the embedded systems | It is cheaper compared to a computer. |
It requires huge number of peripheral devices and their controllers | It is cheaper as it requires less no of peripheral devices and their controllers are microcontroller chip itself. |
The Operating system and other software for the general purpose computers, are normally complicated and occupy more memory space | The operating system(mostly RTOS i.e Real Time Operating System) and other software occupy less memory space. |
