MiSTer FPGA Forum

Hi all, I have a question.
is there a chart out there (for the newest Mister) that displays the minimum required LUTs + RAM for the diverent OS's (cores + peripherals).

For example:
- to run the C64 core (with HDMI display + sound + USB control) the Cyclone V needs x LUT's and need x RAM (is this block ram, SRAM?)
- to run the Amiga core (with HDMI display + sound + USB control) the Cyclone V needs x LUT's and need x RAM (is this block ram, SRAM?)
- to run the ao486 core (with HDMI display + sound + USB control) the Cyclone V needs x LUT's and need x RAM (is this block ram, SRAM?)

I hope this comparisment chart is available?

Cheers and thanks, Jeroen

This should help, however the information may be outdated.

Thx Xbytes,
I guessed the 486 core was pretty hefty, but never reaized SNES took so much resources from the FPGA.
cheers, Jeroen

I'd imagine it's because of the dozen+ additional chips that some SNES carts contained that all have to be recreated in the FPGA, and all the overhead those optional chips require. List of Super NES enhancement chips

Thx Mr. Encyclopedia, also thx for the link.

Another question.
I'm also really into ScummVM games. On the Mister, which core is used to run ScummVM?
I'm interested to know how much LUTs and Ram is needed to run (most) of the games for this excellent platform.

grts, Jeroen

ScummVM doesn't run a 'core', it runs on the linux side on the ARM processor

Thx zakk (cool game zak mc kracken and the alien mindbenders )
So does this mean games with the scummvm engine are emulated??
Cheers, Jeroen

ScummVM is not an emulator. It's a reimplementation of the games it supports, it is basically using the art and scripting assets in the game files and 'running' them in a modern cross platform executable.

ScummVM can run on a variety of platforms (windows, x86_64 linux, ARM linux etc). When you run it on the Mister you are just running the linux arm version of ScummVM

Thx for your answer zakk4223 I appreciate it

Hi all, 2 more questions regarding this topic (scummvm and ram).

1. Scummvm is not using a core (read: making use of the fpga on the de10 board). But a distribution for linux thus making use of the arm processor on the de10 board? Is this true for video and audio, or is audio processed via the fpga (thus making use of more better options for sound like the roland mt32)?

2. The de10 board has 1GB DDR3, but an external ram module (32MB-128MB) is used. Is this because of latency issues with DDR3? The external ram module is this fast ram? and how does this differ from block ram of the fpfa itself?
What type of ram is used in this module and is there any more info (on this forum / site) regarding the use of ram for the many cores like snes and amiga (whdload)?

Thx so much in advance, Jeroen
