Over five months, Wei Zhang developed and refined a hardware-accelerated FFT/NTT processing pipeline in the vic9112/final_project_2025 repository, focusing on scalable digital signal processing for cryptographic workloads. He architected and integrated core modules such as kernel.v and stage_top, implementing RAM control, FSMs, and butterfly-based data permutation using Verilog and SystemVerilog. Wei enhanced clock management, streamlined data flow, and expanded testbench coverage to ensure reliable validation and maintainability. His work included algorithm optimization, build automation, and code cleanup, resulting in a robust, modular RTL baseline that supports deterministic sequencing, improved throughput, and efficient hardware verification for future feature development.

September 2025 performance summary for vic9112/final_project_2025: Focused on architectural improvements to clock management and IOP processing. Delivered a clock selection mechanism for coefficient RAMs, refactored IOP coefficient control, updated decode logic to support sequential processing, and integrated a clock multiplexer into stage_top to route clocks based on operational state. These changes strengthen clock-domain integrity, enable more deterministic sequencing, and lay groundwork for potential performance improvements as the project scales. No major bug fixes were required this month; the work centered on architectural enhancements and maintainability.

June 2025 performance highlights: Delivered substantial Stage_top module and testbench enhancements, enabling more reliable stage processing and improved validation coverage. Implemented FiFFNTT integration with kernel linkage and created kernel_top with a subkernel, enabling tighter kernel-stage collaboration and extensibility. Strengthened core DSP capabilities with updates across kernel.v, kernel_FFT.v, kernel_merged.v, kernel_top.v, and kernel_NTT.v, and added new coefficient and data files (fft_512pt_coef.hex, addr0_511_128b.hex, and (i)NTT coef) to support advanced DSP operations. Expanded validation with updated testbenches, testdata, and TBs (including fiFFNTT_tb.v), and fixed critical I/O and syntax bugs to improve stability. Overall, achieved higher reliability, clearer module boundaries, and accelerated path for future feature work while reducing deployment risk.
