PortalPlayer is a company that makes a chipset using the same name. They are system-on-chip chips with various peripheral connections and two ARM CPU cores. These are used by various iPods, the iRiver H10 and the Rio Karma, among other devices. As of Jan 5th 2007, PortalPlayer was acquired by NVidia Corporation. As a result, the below links to the PortalPlayer documents are from Wayback Machine archives. nVidia's first chips based on the PortalPlayer architecture were named the GoForce series. nVidia's Tegra series also appear to contain traces of this earlier heritage.

Register Descriptions

Reverse-engineered register descriptions are maintained here:

The nVidia Tegra registers are present in this Android Linux kernel branch, for example: arch/arm/mach-tegra/include/mach/iomap.h. A diff of that branch is attached: tegra.patch.bz2

Used in the Second Generation iPod Mini and color iPods (20GB and 60GB) manufactured from about August 2005 onwards (Hardware Revision 0x60004). This seems to be software-compatible with the PP5020 - the ipodlinux code doesn't appear to differentiate between the two, and works on both processors.
