LBP2: Da Vinci CPU v2 - Brief Explaination and Demo

This video shows the first ever LittleBigPlanet 2 working CPU I developed over a period of 3 months. It can handle 15 different instructions and contains 16 bytes within the memory registers.

You can find the level at http://lbp.me/v/0s5dj3 or visit my blog at http://divby0.net!

Sitting in my Comp Sci class I was wondering how difficult it would be to use the microchip feature to make an actual MIPS processor with RAM and how many instructions per game second could be executed. Now, however, I see I wouldn't exactly be breaking new ground and would actually have to really one up for it to be any bit significant...

Nice music choice BTW. Hard to believe that game is over a year old now.

@TheBoredSupremacy Yeah.  It is a reaaal pain the in the ass to be certain. The worst part is developing the programming language and engineering the logic to handle it. You're more than welcome to check out v3 if you want. I'm still in the middle of developing it, but you could probably help me speed things up if you know enough about digital logic.

How full is the therm btw? You really should make a better looking interface, this one is a bit hard.

[Deamosseraph]

@melsomize The therm is around 50%. I would love to make a better interface, which I am aiming for in version 3. This interface is a large improvement from V1 which required knowledge of the exact ASM codes to perform commands.

@Deamosseraph I would be lying if I said I wasn't interested, but I don't know if I have time for that. Not too mention I don't actually have experience with the hardware level aside from simple MIPS and concepts. Though, if V3 is public I might have look it up next time I boot up the PS3.

Het man, im in logic stuff too. I hope you know something about fractals, i recently finished my mandelbrot ser generator in lbp2 it has over 10000 gates and 100000 wires, a screen of 20x20 and 20x24-bit ram. It took me a year to build and the level is filled from bottom to top with multipliers adders and subtractors too run the code. The thermometer is almost full. If you want to see it than you could join me sometime. My psn is tevlon1

[TheXRealXBrapp]

@Deamosseraph Awesome. I'll do that next time I'm on my ps3.

[Deamosseraph]

@TheXRealXBrapp Ahh.. Yeah.. That would be my mistake then. Should be Version 3. Thanks for your interest. If you want, Add me on PSN: Deamos and when I'm on next I'll show ya the current work.

[TheXRealXBrapp]

@Deamosseraph oh, well at the end you said "version 2 will support branch instructions. But anyway, take your time. More time=awesomer cpu.

[Deamosseraph]

@TheXRealXBrapp This posted version is the 2nd version. I am slowly working on version 3, but real life always gets in the way. I am aiming on moving the program storage inside the chip so that branch instructions can be used. This is really slowing me down as I have to do a ton of optimization to allow a large enough pool of memory cells to hold not only a 30+ line program, but some RAM and the registers.
