Freescale Semiconductor
Here the MPC8280 channelizes two E1s (up to 256, 16-Kbps channels).
The local bus can control a bank of DSPs. Data to and from the DSPs can be transferred through the
parallel bus to the host port of the DSPs with the internal virtual IDMA.
The slow communication ports (SCCs, SMCs, I2C, SPI) can be used for management and debug functions.

The CPM supports a total aggregate throughput of 710 Mbps at 133 MHz. This includes two full-duplex
100 BaseT and one full-duplex 155 Mbps for ATM. The G2_LE core can operate at a different (higher)
speed, if the application requires it.
