I am looking for a taxonomy of embedded processors. Which processors belong to which families? Who decends from whom? Does anyone here know of a simple article that describes it? ...
What is the role of stack in a microprocessor? ...
I harbor a secret fantasy (oops, not so secret anymore) to build a simple computer from scratch. I'm looking for an easy-to-use microprocessor to start with. I know about the usual suspects such as the 6502, 68000, 8086, Z80, etc. But I'm wondering if something better is out there. Here's my wish list: Must have: Low clock rate (4-25 ...
I am preparing for a microprocessor exam. If the use of a program counter is to hold the address of the next instruction, what is use of stack pointer? ...
Hi there, I would like to know Whats the difference between these instructions. MOV AX, TABLE-ADDR and LEA AX, TABLE-ADDR P.S: As I am not skilled in this domain, kindly provide a simple solution. ...
Greetings! I'm new to the world of Python and my programming skills are fairly poor but I'm trying to figure a way to use Python to display the output from an EEG circuit (using the OpenEEG circuit http://openeeg.sourceforge.net) The analogue output is amplified and processed via an ADC (in an ATmega8 microcontroller) and is converted ...
Hi, In my work I deal with different micro-controllers, micro-processors and DSP processors. Many of them have 24-bits registers and counters. I know how to use them, this is not my question. My question is why do they have 24-bits register! why not make it 32 bit? and as I know, it is not a problem of size, because the registers are ...
Let's say you have a single (1) Intel/AMD x86-64 bit 2 GHz 8 core processor. Does each of the 8 cores all run at the full 2 GHz or, does each core run at some fraction of the full 2 GHz clock (e.g. 250 MHz)? ...
we can also do queues opration in microprocessor? ...
Hello all, I am a .net web developer. I have several years of experience in this field. Lately, I have received a job proposal for developing .net embedded code on .Net Arm Microprocessors. I wanted to know, what overhead or problems should I expect in developing on microprocessors? I know that developing for the web and for hardware a...
What'll be the behaviour of the 8086 Microprocessor when the stack is full and even then I push something into it? ...
What do 16-bit, 32-bit and 64-bit architectures mean in case of Microprocessors and/or Operating Systems? In case of Microprocessors, does it mean maximum size of General Purpose Registers or size of Integer or number of Address-lines or number of Data Bus lines or what? What do we mean by saying "DOS is a 16-bit OS", "Windows in a 32-...
Why can't we move data directly from a memory location into another memory location. Pardon me if I am asking a dumb question, but I think this is a true situation, at least for the ones I've encountered (8085,8086 n 80386) I am not really looking for a solution for moving the data (like for eg, using movs n all), but actually the rea...
Hello, Is there an easy way to benchmark a piece of software across a wide range of processors? The software I am looking to benchmark is a piece of an SSL Library - I'm looking to test the performance of some of the algorithms as hardware changes. Because I don't personally have the wide range of physical processors which I would li...
I have read that the microprocessor consists of several components, each having same/different "sizes". But what really confuses me is what determines the stated size of a microprocessor as 16-bit, 32-bit or 64-bit... Is it: the the ALU's capacity? the size of the data bus? the size of the address bus? the "least common denominator" o...
I am taking a class in microprocessing, and having some trouble writing a program that will hold a value in a port for two seconds before moving on to the next port. Can any one help this make more sense? I have thought of using NOP but realized thats a bit unrealistic, I have tried ACALL DELAY but for some reason its pulling up as an u...
