I’m currently studying fast numeric code at university, where I’ve been confronted with the problem of optimizing the Walsh-Hadamard transform using SIMD intrinsics. To be honest, I don’t know a lot about the maths behind it, but apparently it has a lot of applications, specifically in cryptography, signal processing and quantum computing. Since it was so much fun to apply my fresh knowledge about intrinsics on a real-world problem, I thought it may be worth sharing this experience here on my blog.
