Why is this advertising-like stuff worth of hackernews?
It means almost an order of magnitude less divisions (and additional calculations as well). Quake had to do this because it would have been too much especially for a low-end Pentium when it was released in 1996. Yes it…
Afaik, Quake does not do one divide per pixel, it is in steps of 8 pixels (see dscan.c in winquake). Yes, there is non divide but instead of taking hundreds of cycles, tables and other approximations could be used. Of…
I think the article says the same. The gba port is impressive. I guess FPU would not be even required with 120 pix horizontal resolution. CM33 does in a single cycle even more: 2 16 bits multiplications, addition and…
The LCD internal memory is write only and it is used just to hold the image being shown. Unlike the GBA where the video RAM is like a GP RAM, just slower.
It's even simpler than this. On the "pregnancy test" Doom is actually running on a pc and the scaled video is sent via usb to the replaced microcontroller which drives the replaced display. Source:…
