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
that a microprocessor can understand. So instruction set is an interface between hardware and software (program). An instruction commands the processor to switch relevant transistors for doing some processing in data. For eg. ADD A, B; is used to add two numbers stored in the register A and...
1 Post Your Answer Jul, 200615 Program counter holds the address of either the first byte of the next instruction to be fetched for execution or the address of the next byte of a multi byte instruction, which has not been completely fetched. In both the cases it gets incremented automaticall...
There are many other factors which includes I/O speed and cost, energy consumption par instruction and so on. So we get a fare deal of understanding of what an embedded system is and what contructs an embedded system. But when you look at the miniature embedded system on right of figure...
It is a 16 bit special function register in the 8085microprocessor. It keeps track of the thenext memory addressof the instruction that is to be executed once the execution of the current instruction is completed.In other words, it holds the address of the memory locat...
Microprocessor: It is a single chip that is termed the brain of the device. It carries out arithmetic and logical operations like addition/subtraction, data transfers, I/O operations, and much more. It also enables operations that help communicate instruction to other components in a larger integ...
The microprocessor revolution of the 1970s and 1980s saw the introduction ofpersonal computers, also known as desktop computers. The first true home computer that came with a monitor display was released to the public in 1977. At the time, many large organizations used expensive and massive comp...
- 8085 What are WAIT states in microprocessors, Explain. - The WAIT state plays a significant role in preventing CPU speed incompatibilities. - Many a times the processor is at a ready state to accept data from a device or location, but there might be no input available. This can lead ...
The instruction set on the 4004 was quite limited; an upgraded version was numbered 4040 by reversing the last two digits. By now, they realized the power of a programmable microprocessor. When they made 8 bit processors, the double wide 4004 was the 8008, and the double wide 4040 was the...
I actually started out in 79 writing some assembly language ( Z80, 8085) test program when I was a technician where I need to test out the boards. They notice me doing that and gave me more. All small little programs. I got a big raise out of it! I studied microprocessor, learning...
