They are also used in industries. ATxmega series is designed for high and complex applications. Their memory size and speed is higher than ATmega series. This series provides DMA direct access memory feature. It also provides the peripheral devices to communicate without interrupting CPU. Atmel has also released its 32 bit microcontroller AVR32 with advance feature which includes video and audio signal processing.
PIC microcontroller pic stands for the peripheral interface controllers or programmable interface controllers these are produced by the microchip technology. Firstly the PIC microcontroller was invented and developed by General instrument in At present PIC microcontrollers are one of the most extensively used microcontrollers due to tremendous features. The architecture of the microcontroller it is a little bit different from the other microcontrollers that are available today.
Here instead of the accumulator resistor the W resistor is used. The difference between the accumulator and W resistor is its position.
It is positioned in a different way than the accumulator in other microcontrollers accumulator is placed at the output of the ALU. So the result of ALU is always stored into the accumulator. However in pic microcontrollers we can store the result either in W resistor or in any other resistor of the data memory also the arrangement of stack memories different in pic microcontrollers here stack is not a part of data memory or your RAM stack memory has its own independent space therefore it has some finite size and this finite size of stack memory depends upon the different pic models that are available.
One another different feature of pic is that they do not have the stack pointer resistor as it is commonly available in most microcontrollers. PIC microcontrollers and AVR microcontrollers use the pipelining technique for the execution of instructions. They are divided into three categories:. They can also be classified as in thus in the form of series like pic 10 series pick 12 pic 16 pic 18 advanced pic 18 pic 24 pic Like this: Like Loading Recommended For You.
They are broadly used in hybrid vehicles to handle engine variants. Furthermore, functions such as cruise control and anti-brake system have been prepared more capable with the use of microcontrollers.
Medical Devices: Moveable medical devices such as blood pressure and glucose monitors use microcontrollers will to show data, thus provided that higher reliability in providing medical results. Peripheral Interface Controller PIC is microcontroller developed by a Microchip, PIC microcontroller is fast and simple to implement program when we contrast other microcontrollers like The ease of programming and simple to interfacing with other peripherals PIC become successful microcontroller.
AVR microcontroller was developed in the year of by Atmel Corporation. The AT90S was the initial microcontroller which was based on the AVR architecture, though the first microcontroller to hit the commercial market was AT90S in the year TinyAVR:- Less memory, small size, appropriate just for simpler applications. MegaAVR:- These are the mainly popular ones having a good quantity of memory up to KB , higher number of inbuilt peripherals and appropriate for modest to complex applications.
XmegaAVR:- Used in commercial for complex applications, which need large program memory and high speed. RISC processors are designed to perform a smaller number of types of computer instructions so that they can operate at a higher speed, performing extra millions of instructions per second MIPS. By stripping out unnecessary instructions and optimizing pathways, RISC processors give outstanding performance at a part of the power demand of CISC complex instruction set computing procedure.
ARM processors are widely used in customer electronic devices such as smart phones, tablets, multimedia players and other mobile devices, such as wearables.
Because of their reduced to instruction set, they need fewer transistors, which enable a smaller die size of the integrated circuitry IC. The ARM processors, smaller size reduced difficulty and lower power expenditure makes them suitable for increasingly miniaturized devices.
Communication Protocols. Memory Architecture. PIC micro-controller was developed by Microchip. This micro-controller is a very fast simple micro-controller in implementation and performance point of view. This micro-controller is easy to program and also it easy to interface with other peripherals. Difference between and PIC : S. PIC micro-controller is faster than micro-controller.
It uses Von Neumann architecture. It uses Harvard architecture. In general if we will see it has more community support than PIC. In general if we will see it has less community support than PIC micro-controller consume low power. PIC micro-controllers are from company micro-chip. It has 12 clock per instruction cycle.
