Define Task in embedded system?
Before we can explain what a "task" is in an embedded system it is important to understand that most embedded systems use a single microcontroller or microprocessor. The microcontroller (MCU) can do only one operation at a time but is fast enough to handle thousands of these operations per second (or much more, depending on the MCU). The application developer decomposes the application into a series of tasks (also known as threads or processes). Each task is given control of system resources by the real-time operating system (or some other scheduler) for a period of time and then yields control to another task. These tasks must share the MCU with all other tasks so it is important that no single task dominates the system. The developer assigns a priority to each task. The scheduler (in the real-time operating system) gives control of the system to the highest priority task that is ready to run, preempting any lower priority task that is currently in control of the system.
What is embedded application architecture?
An Embedded Architecture is a board that is implemented as the embedded system when programmed an embedded architecture is also a target board on which a uProcessor is plugged
What is the definition of an embedded quotation?
An embedded quotation is a quotation that is worked into the sentence that contains it.
What are the necessity of embedded systems?
An embedded system is a special-purpose computer system designed to perform one or a few dedicated functions,[1] often with real-time computing constraints. It is usually embedded as part of a complete device including hardware and mechanical parts. In contrast, a general-purpose computer, such as a personal computer, can do many different tasks depending on programming. Embedded systems control many of the common devices in use today. Since the embedded system is dedicated to specific tasks, design engineers can optimize it, reducing the size and cost of the product, or increasing the reliability and performance. Some embedded systems are mass-produced, benefiting from economies of scale. Physically, embedded systems range from portable devices such as digital watches and MP4 players, to large stationary installations like traffic lights, factory controllers, or the systems controlling nuclear power plants. Complexity varies from low, with a single micro controller chip, to very high with multiple units, peripherals and networks mounted inside a large chassis or enclosure. In general, "embedded system" is not an exactly defined term, as many systems have some element of programmability. For example, Handheld computers share some elements with embedded systems - such as the operating systems and microprocessors which power them - but are not truly embedded systems, because they allow different applications to be loaded and peripherals to be connected.
What are the advantages and disadvantages of using microcontroller over microprocessor?
disadvantage: microcontrollers have got more comlex architecture than that of microprocessors so to understand it's functionality is quite difficult. advantage: microprocessors have got faster speed of execution than that of microprocessor.Also because of microcontroller embedded system got on the peak of it's development to make new electronc devices.
Difference between microcontroller based system and embedded system?
embedded system also include microcontroller.
What is elevator in microcontroller?
An elevator is an electronic device that transports people or goods in a vertical motion. A microcontroller embedded in the control system of an elevator is used to control the elevator's mechanisms.

What is microcontroller 8051?
The 8051 is a microcontroller. It has the MCS-51 core by Intel and was designed for embedded systems in the 1980's. The name of the CMOS version is 80C51. Today the core is still used in microcontrollers from other companies like Atmel, e.g. AT89C51.
What branches of physics are related to calculator?
The branch included is electronics with a bit programming of Embedded for the microcontroller and processor used thus fully comes under electronics
What is a 8051 Micro-controller?
An 8051 microcontroller is a popular 8-bit microcontroller that was first introduced by Intel in 1980. It is widely used in embedded systems due to its simple architecture, low cost, and ease of use. The 8051 microcontroller typically includes CPU, RAM, ROM, I/O ports, timers, and serial communication interfaces on a single chip.

We don't have to bother much about hardware.Also it will take only less effort to change from one microcontroller to another.Its more easy to....More may be there....
Is an embedded chart a simple chart?
An embedded chart can be of any type. What makes it an embedded chart is the fact that it is embedded into a worksheet. The type of chart is not important, so it can be of any type.

What is difference between microprocesser and microcontroller?
An embedded system has historically been defined as a single function product where the intelligence is embedded in the system. It could be anything from a dishwasher to a hearing aid, if that product includes a microprocessor and software. Many of today's embedded systems are looking more like PCs with user interfaces, touchscreens, displays, keypads and more. Still, these are not general function systems but are designed to perform very specific functions. An embedded system makes use of embedded hardware (microprocessor) and embedded software to accomplish its purpose. Embedded software is generally comprised of: * Real-time operating system (RTOS) * Drivers (HW peripheral interface) * Application software
What are different point s between microprocessor and micro-controller?
Microprocessor = CPU Microcontroller = CPU+peripherals+memory A CPU cannot run independently, it needs peripherals and memory circuits. In embedded systems microcontroller designs are easier than microprocessor design. For example 8051 controllers will have EEPROM, RAM, timer circuit, serial port, SPI, GPIO, etc. If ur application need not have all these, just EEPROM, RAM, GPIO is enough then u can go for 8058 CPU with 8055, EEPROM, RAM. In otherwords CPU designs may provide more flexibility to ur Embedded design. whereas microcontroller designs can make designing easier. Hope this may help u !!
