mean that the processor of mcu will check spesfic registers in loop way
while (1)
{
if (PINA = ... ) then >>>>>
if(PINB = ... ) then >>>>>>>>
if(PINC = .....) then >>>>>>>.
}
here the processor polling polling for this register
8051 Microcontrollers were popular computer chips used in Intel computers throughout the eighties and nineties. Though technology has advanced beyond their common use, they can still often be found in engineering schools as tools used in introductory microcontroller classes.
Atmega is IC produced by ATMELPIC is IC produced by MICROCHIP TECHNOLOGIESboth these IC names are used as a prefix for their microcontrollers
The advantage of programmable logic device is in terms of money. This device is cheaper rather than using microcontrollers that has to be certified before someone can use it.
ANSWER The Intel 8051 had integrated RAM, ROM, and various I/O functions. This is typical of microcontrollers. I forget the amounts, probably 4 kB of ROM and 64 bytes of RAM? Newer 8051-compatible microcontrollers have a wide variety of memory and integrated I/O options. (Useless information: the 8051 used 12 oscillator cycles per machine instruction cycle, due to the synchronous way it decoded the instructions, fetched the operands, and stored the results. Newer versions get semi-asynchronous and run the same operands in 4, 3, or even 1 cycle.)
A look-up table is a table of constants stored in program memory -Look-up tables can be used to speed up arithmetic operations -The look-up table may be accessed using the DPTR or PC as a pointer to the start of the table. The A register is used as an index to the table.

The polling booth was hacked during the elections.We need to be at the polling both by midday.
internet polling
polls, polling is a survey process
230 constituencies and 24,000 polling stations
because easy
It is called polling station or polling place.
Polling place
British Polling Council was created in 2004.
Public Policy Polling was created in 2001.
The Perils of Polling was created on 2000-10-01.
Due to many impressive features of microcontrollers, any engineering student likes to work on projects based on microcontrollers. So, on this page, we are going to publish a list of mini projects based on microcontrollers. These microcontroller based mini projects are very useful for the engineering students
