Products Sold on our sister site CrystalGraphics. A silicon chip that contains a CPU. In the world of personal computers, the terms microprocessor and CPU are used interchangeably. At the heart of all personal computers and most workstations sits a microprocessor. Microprocessors also control the bdari of almost all digital devices, from clock radios to fuel-injection systems for automobiles 4 Arm def.
Microprocessor is a programmable device It can be instructed to perform given tasks with in its capability. The programmer selects instruction from the list and determines the sequence of execution for a given task. It takes input from the input device and process the input as it behaves like a CPU and gives the output. Microprocessor is a clock driven semiconductor device consisting of electronic logic circuits manufactured by using a LSI or VLSI technique.
The was later followed in by thethe world’s first 8-bit microprocessor. Then comes that is the 8 bit microprocessor 11 Continued Often the processor is required to manage various different tasks that have to be scheduled somehow and must also deal with outside interrupt sources such as an alarm when something goes wrong.
Real-time systems are those in which timeliness is as important as the correctness of the outputs, although this does NOT mean that they have to be? A real-time system does not have to process data in microseconds to be considered real-time – it must simply have response times that are constrained and thus predictable. Microprocessors are typically used in either reactive or embedded systems.
Reactive systems are those that have an ongoing interaction with their environment – for example, a fire-control system that constantly reacts to buttons pressed by a pilot.
In embedded systems the software system is completely encapsulated by the hardware that it controls. What is difference between microprocessor, microcontroller and microcomputer?

What is a bit, byte, nibble and a word? What is difference between compiler and interpreter?
What is instruction and mnemonic? NOP OUT 8 bit port address copies the contents of the accumulator to the output port specified in the second byte,2 byte instruction 17 Data advvanced operations This group of instructions copies data from a location called a source to another a location called destination without modifying the contents of the source.
All the signals are classified into 6 groups Address bus Data bus Control and status signals Power supply and frequency signals Externally initiated signals Serial input output ports 30 Block diagram of microprocessor It includes Arithmetic and logic unit Timing and control unit Instruction register and avdanced Register array Interrupt control Serial input output control 31 interrupt What is interrupt? Vectored interrupt Non vectored interrupt Enable and disable interrupt instructions Pending interrupts 32 interrupt Interrupt is micgoprocessor process where an external device can get the attention of the microprocessor.
Classification of Interrupts Interrupts can be classified into two types Maskable Interrupts Can be delayed or Rejected Non-Maskable Interrupts Can not be delayed or Rejected Interrupts can also be classified into Vectored the address of the service routine is hard-wired Non-vectored the address of the service routine needs to be supplied externally by the device 33 Interrupts An interrupt is gy to be an emergency signal that may be serviced.
The Microprocessor may respond to it as soon as possible. What happens when MP is interrupted? When the Microprocessor receives an interrupt signal, it suspends the currently executing program and jumps to an Interrupt Service Routine ISR to respond to the incoming interrupt.
Each interrupt will most probably have its own ISR. The DI instruction is a one byte instruction and is used to Disable the non-maskable interrupts. The has a single Non-Maskable interrupt. The non-maskable interrupt is not affected by the value of the Interrupt Enable flip flop. The purpose of the IVT is to hold the vectors that redirect the microprocessor to the right place when an interrupt arrives.
The function of A classified acc to two modes. Contains transistors and is fabricated using HMOS technology.
