2.2. Energy-Aware Processor Design

Many techniques for controlling both active and standby power consumption have been developed for processor cores [11]. Almost all of these will transition to the MPSoC design space, with some of them taking on additional importance and expanded design dimensions. Figure 2-3 shows the processor power design space for both active and standby power [12]. The second column lists techniques that are applied at design time and thus are part of the circuit fabric. The last two columns list techniques that are applied at run time, the middle column for those cases when the component is idle, and the last column when the component is in active use. (Run time techniques can additionally be partitioned into those that ...
