Kromi One is a new home computer for 2D and 2.5D games and creative work, in the tradition of the Amiga. Its own chipset, Aura, runs in the FPGA of the AMD Kria K26; its firmware, KROM, and its operating system, KromiOS, are written for it. A prototype runs today on the AMD Kria KV260.
Kromi One follows the idea of the Amiga, one fixed, fully documented machine you can understand completely, but it is a new platform, not a remake: it runs no old software. Aura draws Full HD at 60 frames per second: sprites, layers, colour grading, AMD FSR 1 upscaling and textured, animated triangles for 2.5D. Programs never touch its registers; the firmware checks every command. Every frame is verified against a reference renderer, bit for bit. A developer edition on the KV260 comes first; Kromi One with its own board follows.

Kromi One folgt der Idee des Amiga, eine feste, vollständig dokumentierte Maschine, die man ganz verstehen kann, ist aber eine neue Plattform und kein Nachbau: Alte Software läuft darauf nicht. Aura zeichnet Full HD mit 60 Bildern pro Sekunde: Sprites, Ebenen, Farbkorrektur, Hochskalierung mit AMD FSR 1 und texturierte, animierte Dreiecke für 2,5D. Programme greifen nie direkt auf seine Register zu; die Firmware prüft jeden Befehl. Jedes Bild wird Bit für Bit gegen einen Referenz-Renderer geprüft. Zuerst kommt eine Entwickleredition auf dem KV260, danach Kromi One mit eigener Platine.
Kromi One at a glance
- What it is
- A new home computer for 2D and 2.5D games and creative work, in the tradition of the Amiga. A new platform, not a remake: it runs no old software.
- Running today
- A prototype on the AMD Kria KV260 starter kit: the chipset draws Full HD at 60 frames per second, the firmware starts the machine, and the operating system, KromiOS, runs on it.
- Processor
- AMD Kria K26 module: four Arm Cortex-A53 cores, all free for programs, plus the programmable logic (FPGA) that holds the chipset.
- Chipset
- Aura, in the FPGA: Klara draws (sprites, rotation and scaling, blend modes, textured and animated triangles), Dora builds the picture (layers composed during scan-out, 3D colour tables, upscaling with AMD FSR 1), Aria plays sound (48 kHz stereo).
- Firmware
- KROM starts the machine and checks every command a program sends to the chipset, in about a microsecond. Programs never touch the chipset's registers, so the chipset can improve without breaking software.
- Operating system
- KromiOS: a desktop in the spirit of AmigaOS, with windows, apps written in Lua and a Terminal. It starts in seconds, with no account.
- Verified
- A reference renderer decides every pixel. The board computes a checksum of every frame it sends and compares it: 432,009 of 432,009 frames exact in a two-hour run; 11,979 of 11,979 in the filmed run.
- What comes next
- A developer edition on the KV260 for early supporters comes first; Kromi One with its own board and case follows. No dates or prices yet.
- Made by
- Sergej Klementinovski, near Munich, Germany.
