NEXT (Bus Bridge)
Network and Streaming Media Devices
- Example: Ethernet, USB, Firewire, 802.11.
- For high throughput should likely be bus master or use a DMA channel.
- More importantly: DMA requires less staging RAM or FIFO in device.
- Shared RAM pool: statistical multiplexing gain.
- The device driver will set up a circular buffer or
linked list of buffers.
