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...
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 locati...
A bus is a set of conductors intended to transmit data, address or control information to different elements in a microprocessor. Usually a microprocessor will have 3 types of buses : Data Bus, Control Bus and Address Bus. An 8-bit processor will be using 8-bit wide bus. Instruction Set ...
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...
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...
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...
Also, the HP9825 has almost identical architecture/instruction set to an early HP2000 series mini computer, HP2114 I think. Logged tggzzz Super Contributor Posts: 21097 Country: Numbers, not adjectives Re: What kind of code is on 1980's, 1990's scope's/etc ? « Reply #33 on: ...
(1) Wasn't my first, that was a C64, but modded up because it was such a fun machine. I've still got the user manual and it has op codes and descriptions of each cpu instruction in the last chapter. How many computers can make that boast these days? - justinhj ...
