Somewhat related but this can go pretty low in amount of code (and data) with a bit of design, here is some experiments and details on the generation of monospace blocky font with very low amount of data (data is encoded into bitfield) and

Is there some tools like this which can simulate old school stuff such as magnetic core memory ?

There is Photosounder which have excellent sound quality (all edit is in frequency domain and it then convert back) For free there is also Virtual ANS and https://www.fsynth.com on the more experimental side (conversion is done

Are you on Linux ? There is a known issue on Linux with the server running in background when you launch the AppImage directly (by clicking on it) so it is actually launched but you can't see it and if you launch it a second time it wi

Guess this is not restricted to interface design for example having quit & save keys shortcut close together...

A VSTi i have used several times for birds & animals is "sounds of nature" by Xoxos, maybe you could take a look at how it is done, my guess is some fast FM modulations. To stay in topic i have synthesized some nature sounds (

The sound server itself (the link) is 100% CPU and does not use the GPU at all. One of the client application however (your description) output RGBA data generated by the GPU.

I don't know if that was a good idea considering there is a soldering problem on the Nexus 5X which shorten its lifetime to around 2 years, CPUs just fail after some times. I preferred to take a Android One device since then, cheaper w

Yes, this is actually how it work however page flipping mechanism require a memcpy, as such it is as effective as not using page flipping and just memcpy a front buffer to display and doing software flipping through pointers exchange, the o

Tried to implement page flipping today and performances are terribly low on the Raspberry PI due to direct draw calls to the video mapped memory... so you need to do a single memcpy to avoid multiple write to the video mapped memory, this r

Did a simple clearing test with a 4 cores Raspberry PI 3B and 1280x768 resolution, i get 30 FPS. However a single core memset (still RPI 3B) for this case is fast : 235 FPS

The time goes into calculating a fullscreen pixels-based effect (so yeah; buffer contents), the point of this library is not the FB implementation which is a simple / bare-metal one. The point is to render graphics content in a consist

I am aware of those, this might land in a future update. The library initial focus was just to get multiple cores to work for graphics task...

A late night mistake that is mostly fixed. (and there are some other typo errors as well, will check it later on) Thank you!
