Figure 1 below shows the architecture of a typical dual-CPU SoC. The blocks in blue implement on-chip redundancy which we call Sphere of Replication (SoR). Each SoR contains identical CPUs (e200z4), eDMA controllers, interrupt controllers, crossbar bus systems, system timers, software watchdog...
A condition, often an error, that causes the program or microprocessor to branch to a different routine. The terms interrupt and exception are very close in meaning. Both can be used to refer to either hardware or software. The only real difference is that an exception usually indicates an ...
