ABSTRACT:
An apparatus (12) and method (80, 120) is described for reducing power consumption in a system (10) having subsystems (34). A controller (40, 40', 40") detects the occurrence of a repetitive operation (62). The subsystems (34, 38) or a power down controller (39) detect (86, 128), whether a subset (60i) of the subsystems (34) is or is not participating in the repetitive operation (62). This preferably occurs during the first iteration (661-662) of the repetitive operation (62). Power controls (36) in or coupled to (39) the subsystems (34), reduce the power consumption of this subset (60i) of the subsystems (34) until the repetitive operation (62) is completed (642), whereupon power thereto is restored (114, 190). In the event of an interrupt (643-644), the subset (60i) is maintained (142) or returned (172) to full power operation until the interrupt (643-644) is finished (144, 174) and the repetitive operation resumes (644-642).
