I have discovered that it seems r0 is always set to 1, meaning INIT2 is never skipped.

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 […]

Impact of Using Extended Registers (r8, r9, etc.) on Code Size and Performance

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 […]

Ensuring 16-bit THUMB Instruction Encoding for Code Execution from SRAM on STM32F103

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, […]

Why is my assembler subroutine for Shellsort not sorting the array when integrated with a C program

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 […]

How to optimize SIMD instructions for double precision floating point operations on Intel Core i7

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 […]
