Meet Aura: Klara, Dora, Aria, Tina, Lina and Ines
The Amiga's chips had names, and so do Aura's parts. Here is what each one does.
The Amiga’s chips had names (Agnus, Denise, Paula), and so do Aura’s parts:
- Klara draws
- Dora builds the picture
- Aria plays sound
- Tina handles sprites and tiles
- Lina runs raster effects
- Ines reads input
Aura runs in programmable logic on AMD’s Kria K26 module. That means a firmware update can give machines already sold new chipset features. A fixed chip can’t do that.
Today Aura needs about 1 μs of chipset time per sprite, so 10,000 sprites take about 10 ms of a 16.7 ms frame. AMD FidelityFX Super Resolution 1 is built into the chipset for sharp upscaling from 720p.
