1.7.2.1 Basic System
In the basic system configuration, shown in Figure 1-9, the G2_LE core is enabled and uses
the 64-bit 60x data bus. The 32-bit local bus data is needed to store connection tables for
many active ATM connections. The local bus may also be used to store data that does not
need to be heavily processed by the core. The CP can store large data frames in the local
memory without interfering with the operation of the system core.
