Hi fellow hobby freeks.
I need to make an LCD cube with 100x100x100 LCDS' and I know that a KEIL CX51 is the best processor for the project.
BUT how can I wire the LCDS' to the processor.
"how can I wire the LCDS' to the processor"
If you don't know such a basic requirement as that, how can you "know" that it's the best one for the job?!
Anyhow, the procedure for you to determine the answer to your question (whichever processor you use) is described here: www.8052.com/.../160143
I think I would go for a full 3D cube of 100MHz 1-clockers. 100x100x100 fast 1-clockers should have quite a lot of computing power to play with - a peak performance of 10^14 instructions/s can't be ignored.
And 1 million processors sending out parts of the video data on the individual serial ports should allow for a quite high total resolution. 19200 baud would be 19.2gbit/s total output capacity - and everyone should know that the 8051 can run at way more than 19200 baud. One full HD image at 24fps with 12-bit/color channel would need about 2.1gbit/s of data. At 19200 baud, the total output capacity would be enough to show one Full HD image on each side of the cube and still have plenty for streaming DTS HD Master Audio.

100x100x100 LCDS'
Wow - One million LCDs
Hope you're not thinking of using wire-wrap!
You could manage with just 60 000 LCD too, if you settle for covering the visible surface.

Maybe OP wants to build a true 3D display? One that actually _has_ depth, instead of just the illusion of depth?
;)
This is more of a FPGA project (at least if you wish to handle DVI/HDMI signals). I've seen the 3d cube displays, even a full color one. There resolution is kind of bad (high granularity).
I am not positive but ... an LCD variant just wouldn't work due to the LCD's obscuring each other.
Maybe the person was thinking 100x100x100 LED's? (why 100 and not 128 or some binary number? sigh)?
As I was saying it looks to be something doable with an FPGA and a pile of driver chips too me.
You could construct your video data in layers and use the HDMI signal to send the 3d data in layers (480p is what 856X480x60 24.65mps?), which the FPGA can split up and display as surfaces in the 3d matrix. do able but I am not sure how good it would look. I believe one needs just the surface illumination and not all the layers between in terms of the 3d data. Hmmm interesting problem.
So what is with the trolling? Are people so bored they like to create problems? Life is way to short to be that bored.

The sentence "[...] and I know that a KEIL CX51 is the best processor for the project." is a quite strong indication that this thread is written by a bored troll, wanting to see how many readers that will take the question seriously, or will argue about 8051 contra ARM contra dedicated hardware.
The OP might have been bored, but the thread got some responses. What does that say about the rest of us?
It says we had a few spare moments in our busy day to entertain ourselves with the thought?
actually 100 X 100 X 9 = 90000 for 9 sided 100 X 100 X 100 cube.
What is a "LCD cube"?

My bedside clock is called an LCD cube, but it don't think its got 100*100*100 LCDs in it (or even 100*100*9 for that matter).

I'm guessing he meant an LED cube, like this:
www.electronicsweekly.com/.../build-your-own-led-cube.html
It would take some time to build a 100x100x100 LED cube containing one million diodes.
Wanting to build such a cube and at the same time saying a 8051 is the best choice seems like a very big contradiction. The video memory for one frame of such a cube would require 128kB of RAM. Being able to run it at 100Hz would require 13MB/s just to write data into the frame buffer, and a further 13MB/s to read out the data to display. It wouldn't be easy to do with a 500MHz ARM9.
