The answer is interrupts or exceptions. In short, the interrupt vector table contains addresses ( function pointers) of interrupt service /routines and exception handler functions. The interrupt vector table is a table of memory addresses of interrupt/exception handler routines. In other words, it d...
This is the heart of the computer system or a server or laptop. It is a small computation unit that is fabricated on a single chip. The components used in building up the chip are transistors, registers, diodes, etc which work together to perform the assigned operation. The microprocessor i...
the 4004. The 4-bit microprocessor was designed for use in calculators and small electronics, though it required external memory and support chips. The 8-bit Intel 8008, released in 1972, had 16 KB of memory; the Intel 8080 followed in 1974 with 64 KB of memory. The 8080'...
A processor, or "microprocessor," is a small chip that resides incomputersand other electronic devices. Its basic job is to receiveinputand provide the appropriateoutput. While this may seem like a simple task, modern processors can handle trillions of calculations per second. ...
Ⅲ What is the difference between a microcontroller and a microprocessor? The controller is a single-chip microcomputer that integrates the main part of the microcomputer on one chip. The microcontroller was born in the mid-1970s. After more than 20 years of development, its cost is getting lo...
1.What are the various registers in 8085?Accumulator register, Temporary register, Instruction register, Stack Pointer,Program Counter are the various registers in 8085 .2.What is Stack PointerStack pointer is a special purpose 16-bit register inthe Microprocessor, which holdsthe address of the top...
Firstly, it disables all interrupts so that microcontroller cannot be able to execute any other interrupt service routine such as watchdog time, etc When you upload your code to a microcontroller, the binary image of code gets stored in flash memory. Because flash is a non-volatile memory. Th...
System call is the way in which a computer program requests a service from the kernel of the operating system. It work like a service provider between user program and system software like operating system. System call allows th...
Computer and OS latencyis the combined delay between an input or command and the desired output. Contributors to increased computer latency include insufficient databuffersand mismatches in data speed between the microprocessor and input/output (I/O) devices. ...
The 8-bit PIC microcontroller from Microchip comes with a 20-pin interface. It incorporates the high-performance RISC CPU that assists in the execution of instructions. The microprocessor also has a crystal oscillator of 20MHz for interfacing purposes and the creation of clock pulses. ...
