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...
(CPU) of a computer. Mainstream microprocessors, such as those of the Intel Pentium or the power pc families, often integrate several additional functional units such as a memory management unit; interrupt controller and bus control unit onto the chip. There is also a tendency toward adding ...
In digital computers, an interrupt is a response by the processor to an event that needs attention from the software. An interrupt condition alerts the processor and serves as a request for the processor to interrupt the currently executing code when permitted, so that the event can be processed...
If we will go back to history the 8051 microcontroller was first invented in the year 1980 by themicroprocessorgiant Intel and gradually it has been accepted worldwide and with the every coming days the importance of the 8051 microcontroller is escalating. When it was invented by the Intel, it...
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...
An interrupt is an exception condition in a computer system caused by an event external to the CPU. An interrupt is an event that causes the execution... Learn more about this topic: Interrupts & Atomic Operations: Definition, Use & Examples ...
A trap is a software-generated interrupt caused by exceptions within a program, such as errors or specific conditions, while an interrupt is typically hardware-generated, signaling immediate attention from the CPU.
High network latency can dramatically increase webpage load times, interrupt video and audio streams, and render an application unusable. Depending on the application, even a relatively small increase in latency can ruin UX. One of the major reasons for poor latency is geography. Highly distributed...
What is a serial communications interface (SCI)? A serial communications interface (SCI) is a device that enables the serial exchange of data -- that is, one bit at a time -- between amicroprocessorand peripherals, such as printers, external drives, scanners and mice. In this respect, it...
How would you justify the use of programmed, interrupt driven, or direct memory access in a variety of different I/O devices? What is the storage capacity of a floppy disk? How many storage cells does each k-input LUT have? What operating system do most supercomputers use?
