MICROPROCESSOR AND MICROCONTROLLER

Detailed explanation-1: -– PIC microcontroller use RISC because there is a perception that RISC is faster than CISC : – Ex: A processor with MUL and other one with only ADD. A processor with (ADD X(i), B, C) and other (ADD, Store).

Detailed explanation-2: -Both AVR (Advanced Virtual RISC) and PIC (Peripheral Interface Controller) are the two popular types of RISC (Reduced Instruction Set Computer) architecture-based microcontrollers.

Detailed explanation-3: -Reduced Instruction Set Computer, or RISC, is a microprocessor design that uses a limited, highly optimised set of instructions rather than the more specialised set of instructions found in other architectures.

Detailed explanation-4: -PIC micro chips are designed with a Harvard architecture, and are offered in various device families. The baseline and mid-range families use 8-bit wide data memory, and the high-end families use 16-bit data memory. The latest series, PIC32MZ, is a 32-bit MIPS-based microcontroller.

Detailed explanation-5: -PIC (Programmable Interface Controllers) microcontrollers are the worlds smallest microcontrollers that can be programmed to carry out a huge range of tasks. These microcontrollers are found in many electronic devices such as phones, computer control systems, alarm systems, embedded systems, etc.
