Exclusive : Nintendo 3DS Chip Analysis Reveals Tiny ARM Core

We've got our hands on the first diffusion image of the floor plan of the Nintendo 3DS processor, otherwise known as the Nintendo 1048 0H, one which shows that Nintendo used a proprietary core based on ARM's technology.

The ARM core itself is slightly smaller than the one on the DSi gaming console, according to Allan Yogasingam, Technical Marketing Manager at Market Analysts UBMTechinsights.

The chip integrates the DMP PICA200 3D graphics IP, which competes against ARM's own Mali and Imagination Technologies PowerVR.

The PICA200 reaches up to 15.3 million polygons and 800 million pixels per second respectively at 200MHz although it is likely that the GPU runs at much lower clock speeds.

Although UBMTechinsights has yet to confirm which ARM core Nintendo used in its chip, we suspect that ARM is sticking to the tried and trusted ARM9 possibly clocked at 133MHz like the DSi.

The gaming console comes with 128MB RAM from Fujitsu, two rear facing VGA cameras and a 2D front facing one, a 3-inch QVGA display and one 3.5-inch WQVGA 3D screen, Wi-Fi and 2GB NAND flash.

It was launched in the UK last Friday and saw hundreds queuing up to get the console at various locations. The console is on sale from Amazon for as little as £187.
