Perfect Oscillators in Less Than One Clock Cycle
A sequel, of sorts, to my 2024 talk, "Branch-Free Oscillators for fun and profit".
An implementation of analog-style oscillators in C++ which, by taking maximum advantage of modern processor SIMD architectures, can generate high-quality band-limited waveforms at a cost of less than one clock-cycle per sample on consumer-grade AMD Zen5 CPUs.
The techniques covered are more widely applicable to a range of algorithms and CPUs and include a high-level view of branch-free stream programming and modern SIMD concerns. Intermediate-level C++ and basic knowledge of microprocessor architecture topics are recommended. Basic to intermediate maths/DSP.
