Worked on the os-chip-design/dtu-soc-2025 repository to architect and enhance a scalable SPI controller subsystem using Chisel and Scala, focusing on digital logic and embedded systems design. Developed a configurable SPI controller core with prescaler-based clocking, flexible data paths, and support for all SPI modes, enabling 64-bit data transfers and robust memory device integration. Introduced visualization and monitoring utilities to aid debugging and performance analysis, while also improving build stability by cleaning up legacy code. The work established a foundation for end-to-end SPI operations, emphasizing maintainability, interoperability, and testability within a modern hardware design workflow.

April 2025 performance-focused update for os-chip-design/dtu-soc-2025. Key features delivered include SPI Controller Enhancements for Memory Device Interface and Flexibility, providing 64-bit data transfers, flexible lengths, prescalers, multi-mode support, and new visualization/monitoring utilities to aid debugging and interoperability. Major bugs fixed include cleanup of SevenSegmentDisplay commented code, removing error-causing lines and stabilizing builds. The changes, implemented via commits such as 2d6b2ce476be9535d44d7512ed2bb2fe9d101bbd, 1e3be15b2a8ffec13407e22dec694a6115f0b311, 6f9350a27db30dbdb3cd58f5e23699caccbf071d, 110e70afd4def9c61ff20b4c27fa07e925d1557b, 8bd9e32048c155d94417a408a65014dd70c66db0, and the cleanup commits 077c40a3ca08b2ef908b1da2301948520dabb762, a7aa5eddd9f8afb5eaaae798171bdccb45ad87c5. These changes improve system stability and readiness for memory-module integration. Overall, the updates enhance interoperability with memory devices, reduce build risks, and accelerate bring-up. Technologies/skills demonstrated include SPI protocol engineering, memory interface design, 64-bit data path implementation, prescaler and mode support, visualization/monitoring tooling, code maintenance, and test updates.

March 2025 monthly summary for the os-chip-design/dtu-soc-2025 repository. Focused on delivering foundational SPI controller work and enhancements, establishing a scalable SPI subsystem foundation with prescaler-based clocking, configurable transfer lengths, and direction control. Implemented a top module scaffold and expanded the general SPI controller to support more flexible data paths, chip-select handling, and a ready/done signaling mechanism. This sets the stage for a full state machine and end-to-end SPI operations.
