I was wondering why 8086 control bus consists of 4 lines I/O read/write and Mem read/write. These are clearly 4 different functions that can be determ ...
I wrote a code in assembly language for the 8085 microprocessor. The code should change uppercase letters to lowercase. Maybe can you help me of findi ...
I have a code that should convert uppercase letters to lowercase using 8085 microprocessor (the GNUSim8085 simulator). However, the code is not readab ...
Assuming that there is a processor that has a 4294967296-byte data memory and a single data cache that contains 131072 lines. The cache is a 1-way set ...
I have stored light sensor values in comb1, as an array in an unsigned int. I am trying to send these values to a microprocessor. The values are taken ...
So, I have this assignment where I need to design a RISC-32-bit 5 stage pipeline. I must support at least 32 (32-bit) instructions and 32 (32-bit) dat ...
So I'm messing around with the Attiny85, my project requires what in Arduino would have been analogRead, I have learned a bit about ADC in this great ...
I was trying to program my ESP32_CAM module, but every time I got this error: Has anyone had a similar problem? ...
why stack pointer is initialized to the maximum value? I only knows that It is the tiny register which stores the last program request’s address in a ...
I have an STM32F407G discovery board and I am trying to turn on an LED without using any example code. I happen to know that the GPIOs require the RC ...
Assume the 16 bit no. to be 256. So, byte 1 = Some binary no. byte 2 = Some binary no. But byte 1 also represents a 8 bit no.(Which could be an in ...
This is my PC's specification: Processor Intel(R) Core(TM) i3-5005U CPU @ 2.00GHz 2.00 GHz Installed RAM 4.00 GB System type 64-bit operating system, ...
This was a question that was previously posed by a prof of mine and I'm assuming the 8-bit register is either CL or CH. I got it working by simply mov ...
My professor claimed that LOOP is faster on 8086 because only one instruction is fetched instead of two, like in dec cx, jnz. So I think we are saving ...
If two or more processor cores copy a variable into their local cache, how C++ handles that? Does &var return a different memory address depending ...
enter image description here Question 1- In a system like the one below, the user is expected to enter a 4-digit password. The first time the program ...
As 8086 has a 16-bit ALU with 16-bit registers, this is how I pictured adding two 16-bit numbers: But my professor said that 8086 did this operatio ...
I have been writing embedded software for just a few years and I have used MSP430, PIC18, PIC32, and Atmel SAM-D21 MSPs and MCUs using Micrium, FreeRT ...
I'm thinking of taking EXP 301 (Windows User Mode Exploit Development) exam. And I did some research on this exam; I came around many articles which c ...
