Jan 1, 2026January 2026 monthly summary for ucb-bar/radiance: Delivered major Floating-Point Unit (FPU) enhancements, consolidating FP work to increase throughput and correctness while expanding precision support. Implemented dual FP pipelines for add/mul and div/sqrt, added a FP division/sqrt decode field, and introduced tag/format encoding for FPU results. Strengthened gating/read logic, added half-precision support, and updated the test infrastructure to reflect the new FP path. Completed extensive testbench work and FP-specific verifications; core FP path stabilized and aligned with project verification standards.

Sep 1, 2025September 2025 monthly summary for ucb-bar/radiance: Focused on documentation overhaul across the project, including Global Command Processor (GCP), Kernel Engine, DMA Unit, and Local Command Processor (LCP); comprehensive barrier unit documentation (warps calculations, threadblock release); kernel driver runtime APIs (memory management, command stream handling, error parsing); and overall documentation coherence with the CP renamed to Gluon across docs, plus scheduling and retry details for the kernel engine. No major bugs fixed this month; primary value delivered through improved developer experience, onboarding, and maintainability.
