- `GNU Make` |
- Completely described in behavioral, platform-independent VHDL |
- Fully synchronous design, no latches, no gated clocks |
- Very small outline and high operating frequency |
- Very low resource requirements and high operating frequency |
- Internal DMEN (RAM, for data) and IMEM (RAM or ROM, for code), configurable sizes |
- One external interrupt line |
- Customizable processor hardware configuration: |
