E-110 MAC Core

Figure 1.10 External Connections to the E-110 MAC
For simplicity of application, all per packet interactions (for example, start
of frame and end of frame) between the E-110 MAC and the system take
place through the system data transport. Using the system data transport
eliminates the need for involvement of a processor at 100 Mbit/s because
the E-110 MAC takes over the per packet data transfer responsibility.
The E-110 MAC conforms to existing IEEE 802.3 standards for 10-Mbit/s
operation and IEEE 802.3u standards for 100-Mbit/s operation. It is
expected that a common application of the E-110 MAC will be as a part
of a larger system in user-specific ASICs. The E-110 MAC therefore
imposes very little system personality regarding word size, byte order,
data flow methodology, or management conventions. Alternatively, the
E-110 MAC can be combined with a minimum of logic circuitry connected
to off-chip interfaces to configure a unique MAC device.
To allow for a variety of network media types and methods of connection
to the media, the MII standard has been adopted for the E-110 MAC. The
E-110 MAC uses the MII on a logical basis only. Any implementation of
the E-110 MAC can be used to connect copper wire or fiber media by
means of a PHY. The PHY can reside either within the same ASIC as the
E-110 MAC or external to the ASIC, as long as the PHY interface to the
E-110 MAC is MII-compatible.
The E-110 MAC function transmits and receives nibbles of data to and
from the media over the MII signal lines. The function handles
independent receive and transmit byte streams between MII devices and
the host. On the host side of the E-110 MAC, the byte streams can be
directed into a system memory or bus structure in a variety of ways, such
as shared or separate DMA channels or direct access to multiple port
memories and FIFOs. The byte streams can also be assembled into
system words as desired.
