What do you mean by Bootloader in Embedded System A boot loader is a small software or program mostly stored in the ROM memory space of microcontroller. It is the first program runs When any computing system is switched on. Sometimes it is also known as Firmware Program, because it is stored in the ROM. […]

What is the Meaning of Watchdog Timer in Microcontroller or Embedded System
August 27th, 2015 Nilesh Chaurasia 
What is Watchdog Timer Watchdog-timer is a timer which, actually reset the embedded system or microcontroller after the timeout specified completes. To avoid the system from reset, the programmer needs to write some instructions (timer restart command) to prevent the timeout of the Watchdog timer. In case of faulty operation, the timer restart command will […] What do you mean by Shared Resource
August 27th, 2015 Nilesh Chaurasia 
Those resources or devices in a processor that are accessed by different instructions at various times during the operation cycle are known as Shared resources. A shared resource can be any device in a system such as memory, printer, register etc. During the execution of complex set of instruction we need to protect our shared […] Instruction Set
August 27th, 2015 Nilesh Chaurasia 
An instruction set covers a number of aspects such as instructions, addressing modes, interrupts, exceptions, registers, etc. This instruction set plays a major role in the programming of a system. And this programming decides the working behaviour of various I/O ports. Talking about the instructions, they are of following types. Data handling and memory operation […] What is the difference between RISC vs CISC
August 27th, 2015 Nilesh Chaurasia 
CISC CISC is a self explanatory term that works towards making the instruction more complex in order to reduce the semantic gap lying between the instruction and machine codes. This complex instruction is a sequence of numerous critical operations. And hence number of clock cycles is taken for the execution of one single instruction. The […] What do you mean by Context Switching
August 27th, 2015 Nilesh Chaurasia 
Context is basically the state or situation of any particular event .when this word is used in technical terms then it refers to the state of the instruction or thread or task or any mode. Context switching can be defined as the storing of the current state of any thread to be performed at a […]
