September 2025 focused on stabilizing Chipyard CI and dependency management to ensure reliable builds amid external tool changes and repo reorganizations. Actions delivered: disabled the CIRCT auto-update workflow to prevent incompatible updates from running in CI, via renaming update-circt.yml to .disabled; updated submodule references to the riscv-tacit organization to resolve dependencies after repository reorganization. These changes directly reduce build failures, preserve reproducibility, and keep development on track while longer-term fixes are pursued. Technologies demonstrated include Git submodule management, CI/CD workflow hygiene, and dependency refactoring.

April 2025 monthly summary focusing on delivering performance improvements and repository hygiene. Key features/bugs delivered: 1) Tacit Branch Predictor Enhancement: Added testchipip dependency and configured a new branch predictor mode in WithTacitEncoder, enabling improved prediction performance. 2) Submodule Pointers Updated to Latest Changes: Updated commit hashes for multiple submodules (rocket-chip, tacit, baremetal-ide, tacit_decoder) to incorporate the latest fixes and maintain build reproducibility. Impact: Enhanced Tacit path performance and more reliable, reproducible builds through synchronized dependencies. Technologies/skills demonstrated: chipyard/ucb-bar stack, testchipip integration, branch predictor configuration, Git submodule management, and build system alignment.

January 2025 performance summary for the ucb-bar/sp24-Baremetal-IDE repository. Delivered core motor-control enhancements, observability, and build tooling improvements with a focus on real-time reliability and maintainability. Implemented Mada timer driver and FOC control test, including SVPWM transforms and PWM updates for motor-control simulations. Introduced performance monitoring (PMU) and tracing, with FreeRTOS integration across the stack and enhanced build tooling (dynamic LLVM paths). Completed API refinements and cleanup to improve maintainability and reduce fragility. The work strengthens evaluation fidelity for motor-control scenarios, improves diagnostics and observability, and lays a scalable foundation for future RTOS-enabled features.

December 2024 (2024-12) monthly summary for ucb-bar/sp24-Baremetal-IDE focused on delivering observable performance improvements, robust testing, and an enhanced build pipeline. Key work spanned DMA-based trace capture, encoding performance tests, PMU sorting validation, trace encoder refactor for locality, and infrastructure improvements to profiling, instrumentation, and benchmarking.

November 2024 monthly summary for ucb-bar/sp24-Baremetal-IDE: Highlights include delivering a Rocket Chip CLINT/PLIC base with chip-header alignment, PMU driver with Embench integration (timer interrupt trigger, counter inhibit and inhibition controls), LLVM toolchain support with LLVM-oriented build improvements, and expanded coverage tooling via embedded gcov and a gcda dump utility. Additional work integrated Embench-PGO with a sample PGO script to enable performance profiling, reinforcing the platform's performance-oriented capabilities and build reproducibility. This month also included build-cleanup and reliability hardening, setting the stage for stable benchmarking and scalable maintenance.
