Over five months, Wei Zhang developed and refined a hardware-accelerated FFT/NTT 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 to coordinate complex transforms. Using Verilog and SystemVerilog, he enhanced testbenches, optimized memory addressing, and introduced clock-domain management for deterministic sequencing. His work included algorithmic optimization, build automation, and rigorous verification, resulting in a robust, maintainable RTL baseline that improved throughput, reliability, and future extensibility while reducing debugging and integration effort.

Sep 1, 2025September 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.

Jun 1, 2025June 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.
