Multiprocessor Systems-on-Chips

2.6. Conclusions

This chapter has surveyed a number of energy-aware design techniques for controlling both active and standby power consumption that are applicable to MPSoCs. In particular, it covered techniques used to design energy-aware MPSoC processor cores, the on-chip memory hierarchy, the on-chip communication system, and MPSoC energy-aware software techniques. The vast majority of the techniques are derived from existing uniprocessor energy-aware systems that take on new dimensions in the MPSoC space. As energy-aware MPSoC design is a relatively new area, many open questions remain.

Other issues to be considered but not discussed in this chapter are the possible promise of globally asynchronous, locally synchronous (GALS) clocking for ...
