Introduction
PortalPlayer is a company that makes a chipset using the same name. They are system-on-chip (SoC) chips, with various peripheral connections and two ARM CPU cores.
These are used by at least 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.

PP5020
Used in the iriver H10, Tatung Elio, Olympus m:robe 100, Fourth Generation iPods, iPod Mini, color iPod, U2 iPods and iPod Photo.
According to the publically available 5020 Product Briefing, the PP5020 consists of:
- Dual 32-bit ARM7TDMI processors
- Up to 80MHz processor operation per core with independent clock-skipping feature on COP
- Efficient cross-bar implementation providing zero wait state access to internal RAM
- Integrated 96KB of SRAM
- 8KB of unified cache per processor
- Six DMA channels
PP5022
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.
