40-Bit Accumulator
The accelerator also incorporates an automatic accumulator function, permitting the implementation of multiply-
and-accumulate and divide-and-accumulate functions without any additional delay. Each time the accelerator is
used for a multiply or divide operation, the result is transparently added to a 40-bit accumulator. This can greatly
increase speed of DSP and other high-level math operations.
The accumulator can be accessed any time the multiply/accumulate status flag (MCNT1;D2h) is cleared. The
accumulator is initialized by performing five writes to the multiplier C register (MC;D5h), LSB first. The 40-bit
accumulator can be read by performing five reads of the multiplier C register, MSB first.
Ethernet Controller
The DS80C410 incorporates a 10/100Mbps Ethernet controller, which supports the protocol requirements for
operating an Ethernet/IEEE 802.3-compliant PHY device. It provides receive, transmit, and flow control
mechanisms through a media-independent interface (MII), which includes a serial management bus for configuring
external PHY devices. The MII can be configured to operate in half-duplex or full-duplex mode at either 10Mbps or
100Mbps, or can support 10Mbps ENDEC mode operation. The system clock (external clock source after internal
multiplication or division) must be a minimum of 25MHz for use of the Ethernet 100Mbps mode.
For half-duplex mode operation, the DS80C410 shares the Ethernet physical media with other stations on the
network. The DS80C410 follows the IEEE 802.3 carrier-sense multiple-access with collision detection (CSMA/CD)
method for accessing the physical media. The MAC waits until the physical carrier is idle before attempting a
transmission. Having multiple stations on the network results in the possibility of transmissions from different
stations colliding. When a collision is detected, the MAC waits some number of time slots (according to an internal
back-off timer) before attempting retransmission. Unless instructed otherwise, the MAC automatically attempts to
retransmit collided frames up to 16 times before aborting the transmit frame. As a means of flow control when
receiving data, the MAC uses a back-pressure scheme, transmitting a jamming signal to force collisions on
