SwiftShader: Reference Implementation and Fallback

on YouTube ↗15m

" summary

SwiftShader is a CPU software renderer that JITs per-draw code with a reactor language and LLVM/Subzero, currently passing OpenGL ES 3 dEQP and used as the OpenGL ES fallback in Android Studio and Cloud Android. Architecture uses 128-bit vectors now, plans to widen to AVX-512 256/512-bit, move from scanline multithreading to tile-based rasterization, ingest SPIR‑V to become Vulkan-focused, and aim to serve as a Vulkan reference implementation and inexpensive cloud fallback capable of scaling to 48-core servers (~6 TFLOPS).
