Image Processing Unit (IPU)

Figure 3.6. Block diagram of the Playstation 2 - Image Processing Unit

The Image Processing Unit is part of the Emotion Engine and performs MPEG-2 macro block decoding, color space conversion and vector quantization for 2D graphics data. This graphics data can be frames from an MPEG-2 movie or compressed textures for 3D models.

There really isn't much more to the IPU, it decodes image data very quickly and thats about it.
