Unitron

Unitron is a retro-inspired 32-bit RISC-V mini computer implemented as a softcore system on a Xilinx FPGA. Designed as a flexible platform for exploring embedded compute architecture, Unitron brings together a custom processor pipeline, a deterministic memory subsystem, and a suite of peripheral interfaces to form a cohesive, low-level computing environment.

The system emphasizes transparency and control at every layer. Its FPGA-based implementation allows researchers to inspect, modify, and extend the processor architecture, experiment with bus protocols, and evaluate hardware-software interactions that are often hidden inside fixed silicon. Unitron provides a practical foundation for studying instruction-level behavior, memory hierarchies, and peripheral integration within a fully customizable compute stack.

I am currently preparing a full breakdown of Unitron's processor architecture, FPGA implementation, memory design, and peripheral subsystem.

The first public release will include an overview of the platform, its hardware foundations, and the architectural concepts that drive the system. Please check back soon.
