- Jul 6, 2026 Lookup Tables, Carry Chains, and the Routing Fabric How a configurable logic cell implements arbitrary Boolean functions from SRAM bits, why adders get a dedicated carry path, and why interconnect rather than logic sets the achievable frequency. hardware engineering
- Jan 19, 2026 Embedding Layers as Learned Lookup Tables An embedding table is a matrix indexed by token id whose rows receive sparse gradients; its memory arithmetic, initialization, and weight tying decide what a model can learn from rare inputs. deep learning
- Dec 5, 2025 Marching Cubes and the Case Table That Cannot Be Interpolated How a 256-entry table turns a cube of eight samples into triangles, why edge interpolation places the vertices, and where the classic ambiguity creates holes or spurious connections. scientific computing
- Dec 21, 2023 Perceptually Uniform Colormaps and the Failure of Rainbow Ramps How a scalar field becomes color through a lookup table, why monotonic lightness and equal perceptual steps are the two constraints that matter, and where banding and false contours come from. scientific computing
