Hardware description

The IP Gateway hardware is based on the 68360 Motorola processor, which is a dedicated
smart CPU with Ethernet and I/O controller. In addition to the communication capabilities, the
IP Gateway has powerful processing capabilities, using 32 Mbytes (8 Mbytes X 32 bit) of
DRAM and 1 Mbyte (256 Kbyte X 32 bit) of FLASH memory.
A simplified block diagram of the IP Gateway hardware is provided in Figure 3-1.
