PROFILE
Joshua
During a two-month period, Jyou contributed to the ucb-bar/radiance repository by architecting and refactoring the Load Store Unit (LSU) core, focusing on memory operation management and interface design. Leveraging Chisel, Verilog, and C++ FFI, Jyou implemented per-warp queues, memory space separation, and packetized request handling to improve throughput and predictability. The work included comprehensive documentation updates, clarifying ISA encoding and memory organization, and introduced testbench scaffolding for early validation using Cyclotron memory simulation. Jyou also addressed parameterization bugs, stabilizing builds and configuration. The depth of these contributions established a robust foundation for future performance and verification efforts.

Oct 1, 2025October 2025 focused on advancing the LSU groundwork in the Muon stack for the ucb-bar/radiance repository, establishing core design foundations, interfaces, and memory-request/response handling. Completed initial draft and documentation, reached compilable status, and began testbench scaffolding and integration work with Cyclotron memory simulation to enable early validation. Addressed a parameterization risk with a bug fix to prevent stack overflow by correcting sourceIdBits and refactoring LsuQueueToken.width to MuonCoreParams. Initiated test harness work (C++ FFI in Cyclotron.cc, Verilog memory module, and unit-test boilerplates) to support future verification efforts.
