Good day guys, this code here is part of the initialization code for a firmware of an STM32F030 microcontroller, disassembled using Radare2. It is executed after the clock initialization but […]
My program outputs encoded instructions, and each line represents an independent set of instructions, like this: 0x81FB4300000090 0x69FC4300000090 0x81FC4300000090 0x69FD4300000090 0x81FD4300000090 0x69FE4300000090 0x81FE4300000090 0x69FF4300000090 0x81FF4300000090 0x00054400000090 0x01054400000090 0x02054400000090 0x03054400000090 0x08054400000090 […]
I have a question about using the extended registers as in r8, r9, r10, …. , I want to use them frequently in my program, but I’ve noticed a problem […]
I’m working on a project where I want to execute code from internal SRAM on an STM32F103 as an exercise. My goal is to write some THUMB assembly by hand, […]
In a group work where we are trying to integrate an assembler subroutine for sorting numbers `Shellsort` with a `C` program, the sorting algorithm has been tested as a standalone […]
I want to optimize a computationally intensive loop using SIMD instructions on an Intel Core i7 `12700K` processor and 32GB of DDR4 `3200` memory , to boost the performance for […]
Write a C function to swap all odd and even bits in an unsigned integer. Bit positions 0, 2, 4, … are considered even bits, and positions 1, 3, 5, […]
I am debugging a program on an `x86-64` system `Ubuntu 22.04` `GDB v10.2` `GCC 11.2.0` using `GDB` and encountered an unexpected behavior. I was inspecting the value of the `rbx` […]
I’m working on a network server application in assembly language so I can understand low level networking concepts. So I’ve implemented a socket server using assembly language system calls, but […]
