Debug features

One of the most important features in debugging is the ability to set breakpoints. UltraSPARC-III has the feature of setting watchpoints, and they can be taken on both virtual as well as a physical address and are fully controllable via software. Another debug feature is clock control. This mechanism allows for the precise stopping of the internal clock, using one of the three methods: scan, a logic analyzer, or using watchpoints. We can now use one of the techniques to probe into the processor and watch out for any potential problems.
