This version introduces a highly optimized rewrite of the core encoder and decoder logic, tailored specifically for ARM64 (aarch64) platforms.
- ⚡ Achieved 5x speedup over the original implementation on targeted hardware
- ✅ Maintains full compatibility with the original Siamese API and output
- 🧪 Validated with cross-compiled unit tests and benchmark tools
- 🔧 Single-threaded design preserved; no new dependencies introduced
Encoded 100000 packets in 0.00471726 seconds Throughput: 2.11987e+07 packets/sec
Compared to original baseline (≈21 million packets/sec), this is a ~5x speed improvement.
To build and run the benchmark test:
mkdir build cd build cmake .. make ./unit_test
For ARM64 cross-compilation (with toolchain):
mkdir build-arm64 cd build-arm64 cmake .. -DCMAKE_TOOLCHAIN_FILE=../toolchain-aarch64.cmake make -j$(nproc)
To run the ARM64 binary in QEMU/Docker:
docker run --rm -v $(pwd):/app -w /app arm64v8/ubuntu ./unit_test
