Welcome to VRM21 Studios — Versatile Reconfigurable Modules

Vision, Rêve, Magie ✨

I am an Electrical Engineering graduate specializing in Digital IC Design, RTL Engineering, and Hardware-Software Co-Design. I am passionate about bridging the gap between low-level hardware architecture and high-level software control.

The VRM21-Studios repositories collectively document a self-directed exploration of digital hardware, ranging from fundamental DSP building blocks and data transformations to processor architectures and AI accelerators.

The goal is not simply to reproduce existing algorithms in RTL, but to understand how mathematical and computational concepts are translated into practical hardware architectures, and how architectural decisions affect resource utilization, throughput, numerical behavior, and system integration.

• Digital IC & RTL Design: Writing highly optimized, reusable Verilog for FPGAs.
• Computer Architecture: Custom RV32I RISC-V cores and AXI4/AXI-Stream interfaces.
• Hardware Acceleration: High-performance Audio DSP pipelines (QMF, FIR/IIR filters, Spatial Audio, Spectral Processing) and AI architectures, including Spiking Neural Networks (SNNs) and Systolic Arrays.
• HW/SW Co-Design: Utilizing Xilinx Vivado, Vitis, and the Python PYNQ framework for seamless IP control across platforms such as Zynq UltraScale+, Kria KV260, and KR260.

My capstone and independent research heavily involve Xilinx adaptive SoCs. I have architected the VRM Series SoC—a system utilizing a custom RISC-V CPU to orchestrate complex DSP hardware accelerators.

True to its origins in Voix, Rythme, Musique, my pinned repositories feature reference RTL implementations of various audio DSP nodes. These modules are designed with maximum flexibility in mind, ready to be reconfigured for diverse applications.

• Expanding my knowledge footprint into Data Science and Machine Learning to further complement custom hardware AI accelerators.
• Preparing and structuring robust RTL architectures for academic research and manuscript publications.
