The digital entertainment re-evolution starts with silicon technology. The PortalPlayer platform is based on the 32-bit ARM7TDMI processor core, which offers a unique combination of high performance, low power and software scalability to future ARM-based cores. We extend the ARM’s power with a unique, and patented, architecture that combines multiple processors in a single chip to offer twice the performance of alternative approaches. This performance advantage enables support for more complex encoders and watermarking algorithms, audio post processing effects such as stereo expansion, and 56K soft modem and networking connectivity enhancements. With PortalPlayer, system designs have the performance headroom to accommodate the ambiguity of the evolving digital music market. PortalPlayer products also feature a broad range of on-chip interfaces, helping to lower total system chip count while reducing design complexity. Our baseline platform, the PP50XX family, includes: On-chip SRAM and cache LCD controller and bridge interface Direct memory interfaces to all major removable media types including Memory Stick, MultiMedia Card, Smart Media Card, Compact Flash, DataPlay, and Iomega PocketZip (previously Clic!) Up to four ATAPI devices supported USB 1.0 and RS232 interfaces Low cost 208 TQFP or ultra-small Chip Scale Package for portable devices
