Reconfigurable Architectures: Generalities,Open-source and emerging-technologies
Talkat Algorithmic Foundations for Emerging Computing Technologies Boot Camp 2025 · 2025-09-08..09-12·
summary
Covers FPGA microarchitecture: fractionable LUTs, CLBs with dedicated carry chains and DSP macros, and island-style routing plus placement/routing tradeoffs; describes OpenFPGA as an XML‑driven open‑source flow that generates fabric, bitstreams and GDS for rapid prototyping (examples: 160k LUT midrange die, 12 nm tapeouts, RISC‑V+FPGA boards) and supports custom systolic primitives; explores polarity‑controlled transistors and S4 steep‑slope modes that enable compact XOR/majority gates and motivates majority‑inverter graphs for new EDA co‑design.
