    A soft-core processor is a microprocessor core that can be implemented entirely using digital logic synthesis. It is typically created on a programmable hardware like a field programmable gate array (FPGA). The key feature of a FPGA is that it is reconfigurable with different digital designs allowing functionality to be changed unlimited number of times…

    A microprocessor by itself is not a computer. To be functional, the microprocessor must be connected to other ICs that provide the memory and I/O capability. A microcontroller is a computer on a single IC, designed specifically for control applications. It consists of a microprocessor, memory (RAM and ROM), I/O ports and can have additional…

    The CPU clock dictates how fast the processor can process the data, and a microprocessor having a clock speed of 3 MHz means that it can process data internally 3 million times a second at every clock cycle. The crystal quartz oscillator is the most appropriate frequency determining device in virtually all microprocessors, microcontrollers, PICs…

    A microcontroller is essentially a computer on a chip. It contains a processing unit, ROM, RAM, Serial communication ports, ADCs, etc. In other words, a microcontroller is a computer but without the monitor, keyboard and mouse. They are called microcontrollers because they are small (micro) and because they control machines, gadgets, etc. With a microcontroller…

    To make a change in functionality of a digital circuit, the hardware circuitry must be modified and this may require a redesign. For simple design tasks, this might work however in many mechatronic systems; the control tasks may involve complex relationships among many inputs and outputs which makes hardware solution impractical. A more practical, and…
