Why 8051 is called 8 bit micro controller?
A: Because it can only control 8 bits of data.
How can you say whether the controller is 8-bit controller or a 16 bit controller?
the uc is 8 bit or 16 is depended on ALU and speed of process and seeing the ports
How do you justify that 8051 is an 8-bit microcontroller?
The 8085 is called an 8 bit microprocessor because the accumulator is 8 bits in size. This means that the primary data size is 8 bits. This is true even though the address bus, certain registers, and certain register operations are 16 bits in size.
When was 4 bit 8 bit 16 bit 32 bit and 64 bit micro processors invented?
The year of 1972.
Safety automation of car project can be carried out using which micro contrller?
One of the least important considerations at the beginning of an automation project is the micro-controller. There are a wide range of them available and they offer a vast array of functionality. The major manufacturers of micro-controllers offer tiny 8 pin devices through 100 pin ICs that have a remarkable set of functions. Before thinking about the micro-controller to use, it is vital that the functional specification of the final product is considered. Without that specification, choosing a micro-controller is nothing more than guess work.
Why the name 8085?
bcoz its operate on 5v only.it is a 8 bit micro processor.800 is series 5 is the voltage
Why 8051 microcontroller called so?
Because it is 8- 8-bit controller (8000 series) 5- It has 5 interrupts 1- It has only one serial communication port
What is a 32 bit counter?
This is the the thing for micro controller . Normally in microcontroller operation we used to give the clock pulse to connected circut chips .One chip requires 4 clock pulse .then the second, third vise versa . By which the pulse starts from 4 is for first chip, 8 is for second chip(4+4), 16(4+8+4) is for thir.............Like that depending upon the requirement of the clock signal for chips we used to tell 16 bit counter , 32 bit counter ect.
How does DMA work?
There are signals DACK, DRQ, and TC. When a peripheral wants to move a byte or 2 bytes into memory (is dependent on whether 8 bit or 16 bit DMA channel is in use -- 0,1,2,3 are 8-bit, 5,6,7 are 16-bit), it issues DRQ. DMA controller chats with CPU and after some time DMA controller issues DACK. Seeing DACK, the peripheral puts it's byte on data bus, DMA controller takes it and puts it in memory. If it was the last byte/word to move, DMA controller sets up also TC during the DACK. When peripheral sees TC, it is possible it will not want any more movements,
Why are 8-bit and 16-bit systems still around?
Because they are simple and easy to implement. You can build a low to medium end controller with an 80188 (high integration 16 bit computer based on the 8088) with very few parts.
Why the name is given as picoblaze to picoblaze microcontroller?
Well, I would imagine it is related to MicroBlaze being a 32-bit processor, PicoBlaze being 8-bit is a smaller,lighter processor, hence Micro -> Pico.
What has the author C J Unsworth written?
C. J. Unsworth has written: 'Design of an 8-bit greyscale active matrix LCD controller for use with T.F.T. displays'
