Hey guys! I just wanted to mention that I have now finished my CPU project that I have been working on since the Beta test. What my level does is prove that LittleBigPlanet 2's addition of Logic Gates allows for the construction of highly advanced circuits including the ability to create simple working computers.

Pressing the X button will type a button from the keyboard, and Circle will input the command in to the CPU. Triangle will exit the keyboard and mouse. I know it all sounds a bit complicated and this level is more geared towards those with an understanding of Computer Engineering and Advanced Logic. I am planning on eventually doing a second version of the CPU to be distributed to players to use in their own levels to handle advanced logic functions. In addition, I am also planning on starting up the next version of my Logic Labs series to help explain some of the new LBP2 Logic and how to use it.

Hot ****! I'm still working on my memory module. You have completely outdone what I'm sure I'll ever be able to find time and concentration to finish. Not that I won't try, mind you!

Haha! Yeah. Memory modules are not too bad to make, however they are a bit time consuming for my liking. Largest problem with them is creating a Bus line using a series of OR gates for each bit, IE 2^n. If you ever need help, I'd be glad to assist!

Wow. I just finished a 10-digit BCD addition calculator. Yet I have no clue what you just said. Anyways, I queued your level, and i'll check it out.

This thing can do addition too, however it is limited to only 3 digits to a maximum of 255... I'll try to get that worked out on the next version. Yeah, check it out. I know its pretty difficult concepts to grasp, if you need an idea on what i've done check this article on Wikipedia http://en.wikipedia.org/wiki/Assembly_language

I've have started to provide a bit more information on how to use the CPU and some info on the next version on http://divby0.net

Very nice! I used a similar method for memory when creating my calculator (http://lbp.me/v/wtzfny). In order to store the result I used 2 32-bit registers (with R/W and reset inputs): one for the result and one for the number being entered. Used some BCD adders and 9's compliment converters to do the addition and subtraction. The logic system in LBP2 is just plain amazing... things like this shows just how powerful it is!

Hehe i will give hint to aya about it, he was also working on microprocessor but i think he aimed on some specific emulation. But imo use of full packed CPU is little unpractical in regular levels, must efficient way to do is to build logic for your own needs. For example why you need big back-part CPU to make +1 -1 operations if you can do selector based counters or if you need more you can use simple set of adders or multi tick the selectors if you lazy. Well i got quastion, how much thermo it takes?

Well i got quastion, how much thermo it takes? When applied to normal LBP levels, you are correct.. a CPU/microprocessor is pretty useless. However, imagine having the ability to create programs & execute one in level, then the game really changes. As for Thermo, the first version takes up 90% of the level. However, it is the 14 segment displays & registers that consume a good portion of this. I am already in works of the second version, without the displays and have the thermo down to about 15% total.

Ok Guys! I just finished with the actual second version of the Microprocessor itself today! I will be code naming it Da Vinci and should have it ready for public release by Saturday or Sunday depending on how quickly I can put together the programming and side loading program executers.... Thats right, You are going to be able to program with this sucker by the time I am done. Right now, as it stands the updates will be: 14 Instructions -8 ALU based functions, including Adding, Subtracting, ANDing, ORing, Inverting, XORing, and Shifting Left/Right -8 Bit Data Width -4 bit address line (Expandable to 8 bit Address Line, if someone needs a larger CPU) -8 bit Output -16 Bytes of RAM -3 Special Purpose Registers -2 ALU Registers -1 Working Register -The Ability to Write your Own Programs and execute them! Again, I plan to be finished with this very soon so keep your eyes open here, or at http://divby0.net

Wow thats amazing i qued so i can check it out. i have a quick question though, did your PS3 ever crash from running so many wires? I know mine crashed when i was working on a password system which used a lot less wires then yours.

Wow thats amazing i qued so i can check it out. i have a quick question though, did your PS3 ever crash from running so many wires? I know mine crashed when i was working on a password system which used a lot less wires then yours. It crashed a few times. However, my biggest problem was slowdowns from running so many wires within a chip. Instead of doing it in a chip, I now construct on a Giant Dark Matter Piece which has seriously sped up my prototyping. Also, Keep in mind, the version posted in the level that you queued is the older version of the CPU
