Arm64 Assembly Programming

Unlock the full performance potential of the Raspberry Pi's Cortex processor. Arm64 assembly allows you to write highly optimized code, bypass compilers, interface directly with the kernel, and harness advanced hardware accelerators like NEON SIMD.

Arm64 Assembly Mastery Route

1. Introduction to Arm64 Assembly

Configure your build environment, learn standard assembler (as) and linker (ld) commands, and compile your first register-based hello world code.

2. Registers and Basic Instructions

Master the core Arm64 architecture: General-Purpose registers (X0-X30, SP, ZR), floating-point registers, arithmetic, logical data operations, and memory load/store instructions.

3. Control Flow and Branching

Implement logic structures in assembly. Learn how processor flags, conditional branch instructions (B.cond, CBZ), and loops control execution flow.

4. Functions and Stack Management

Understand the AAPCS64 calling convention. Learn how parameters are passed via registers, manage the stack frame (SP), handle link register (LR) storage, and build nested functions.

5. Interfacing with C++ and GPIO

Write mixed-language applications. Call assembly routines directly from C++ source files, pass data across boundaries, and control physical Raspberry Pi GPIO pins using low-level memory maps.

6. NEON SIMD Vector Programming

Harness parallel computing. Learn how to use NEON vector registers and instructions to process multiple data elements simultaneously, accelerating image processing pipelines and math solvers.

7. Inline Assembly in C++

Embed raw assembly blocks directly inside your C++ code. Master GCC extended asm syntax, input/output constraints, clobber lists, and low-level instruction mapping.
