Design Challenges
The key requirements of a
microprocessor for the home
entertainment gateway application are
connectivity and price/performance.
Processors for this application require
dual Fast Ethernet interfaces for routing;
a USB 2.0 device controller; and a PCI
bridge to interface to the IEEE 802.11a/
b/g radios, (serial) ATA storage
controller, MPEG2/AC3 video/audio
