PROFILE
Riccardo Giunti
Worked on the pulp-platform/spatz repository, delivering four hardware features and a bug fix over four months focused on RISC-V vector processing. Developed vector floating-point comparison instructions, implemented comprehensive vector masking, and added support for scalar-to-vector floating-point transfers, enhancing both performance and correctness in vector workloads. Refactored clock gating and optimized vector register file operations to improve scalability and reduce power consumption. Used SystemVerilog and C to design, test, and verify hardware modules, addressing issues in test infrastructure and vector division. The work emphasized robust test coverage, maintainable hardware design, and efficient handling of floating-point and vector arithmetic operations.

Jun 1, 2026June 2026: Delivered Vector Functional Unit vfmv.f.s instruction support in pulp-platform/spatz, including implementing the vfmv.f.s instruction in the VFU, updating operand selection logic for scalar-to-vector transfers, and adding tests validating vfmv.f.s functionality. This work fixes a bug in the VFU's handling of scalar FP values within vector operations and enables more efficient, reliable vector code paths. Commit d81d21c991c19ca0e1a231b10ba2ea4e9844f2fc ([FIX] vfmv_f_s in VFU).

May 1, 2026May 2026 monthly summary for pulp-platform/spatz focusing on architectural refinement and bug fixes in the VRF and vregfile components. Delivered two main items: a Clock Gating Refactor in vregfile to improve the structure of the column clock generation, and a Vector Register File Byte-Selective Read/Write fix to address a vdiv stall by ensuring only significant bytes are processed. These changes enhance scalability, maintainability, and vector arithmetic throughput, while reducing stalls and power/complexity in the vector path.
