Arm Assembly vs RISC-V

Write AArch64 assembly when reverse-engineering iOS/Android binaries, bringing up bare-metal firmware on Cortex-M/A silicon, or hand-tuning NEON/SVE kernels where the compiler leaves performance on the table — nothing else gives register-level control on the chip running nearly every phone on Earth meets developers should learn risc-v when working on embedded systems, iot devices, or custom hardware accelerators, as it offers flexibility and cost savings through its open-source nature. Here's our take.

Arm Assembly

Nice Pick

Write AArch64 assembly when reverse-engineering iOS/Android binaries, bringing up bare-metal firmware on Cortex-M/A silicon, or hand-tuning NEON/SVE kernels where the compiler leaves performance on the table — nothing else gives register-level control on the chip running nearly every phone on Earth

Pros

• Skip it for general embedded application logic: C plus intrinsics gets 95% of the speedup at a tenth of the debugging pain, so reach for that instead
• Related to: gcc, gdb

Cons

• Specific tradeoffs depend on your use case

RISC-V

Developers should learn RISC-V when working on embedded systems, IoT devices, or custom hardware accelerators, as it offers flexibility and cost savings through its open-source nature

Pros

• It is particularly valuable for projects requiring tailored processor designs, such as in academia, research, or startups aiming to avoid proprietary ISA licensing fees
• Related to: instruction-set-architecture, embedded-systems

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Arm Assembly is a language while RISC-V is a platform. We picked Arm Assembly based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Arm Assembly wins

Based on overall popularity. Arm Assembly is more widely used, but RISC-V excels in its own space.
