Sleeping device(s) may be changed from a sleeping state to an awake state using a multicast packet that sent to a multicast address of a multicast wake-up group. The packet may include an identifier for one or more particular device(s) in the multicast group, which, when received by the device(s), causes the device(s) to wake up.

A system for providing broadcast content includes at least one content source for broadcasting content, and at least one terminal. The terminal can receive and consume content for a selected channel x, which is one in a set of ordered channels of broadcast content. The terminal can also change channels from the selected channel x to an adjacent channel x±1 in the set of n ordered channels. In response to changing channels to the adjacent channel x±1, the terminal can receive and consume content for the adjacent channel x±1. The terminal can receive and store content for Y next adjacent channels (x±1)±y, y=1, . . . , Y in buffer memory. Content for the next adjacent channels is stored based upon the direction the channel is changed and in response to changing channels.

In one embodiment, a method for controlling an instruction cache including a least-recently-used bits array, a tag array, and a data array, includes looking up, in the least-recently-used bits array, least-recently-used bits for each of a plurality of cacheline sets in the instruction cache, determining a most-recently-used way in a designated cacheline set of the plurality of cacheline sets based on the least-recently-used bits for the designated cacheline, looking up, in the tag array, tags for one or more ways in the designated cacheline set, looking up, in the data array, data stored in the most-recently-used way in the designated cacheline set, and if there is a cache hit in the most-recently-used way, retrieving the data stored in the most-recently-used way from the data array.

A proposal for power management control of an interconnect structure based on power state transition control. The power state transition is based on generating early warning signals and an idle timeout value setting based on response time and detection of subsequent requests.

When chip is in stand by mode, system operation timer of the chip is closed so that each module in the chip stops working. Control is started up under slow timer to maintain save mode so as to reach purpose of reducing power consumption and saving electricity. In order to keep synchronization to base station when save mode exits, the invention designs a calculation method to keep good synchronization to base station when save mode exits, and to possess very small frequency deviation. Comparing with prior art, the invention possesses advantages of few control signals, easy of implementation, controllable time in save mode, and small frequency deviation.

A cooling box (1) comprises a main body unit (2) that has a storage chamber (20) the top surface of which is open and which is surrounded by thermal insulation walls, a door (3) that opens and closes the top surface of the storage chamber (20), a cooling unit (25) that is disposed in a side wall (20a) of the storage chamber (20) and that cools the storage chamber (20), a cold storing bodies (30) that have sealed therein a cold storing agent (31) that freezes due to cooling by the cooling unit (25), and retaining members (41, 42) that retain the cold storing bodies (30), wherein: the retaining members (41, 42) have a ring-shaped frame (45) that engages with the storage chamber (20), and have a support part (46) that is provided upright further towards the inner circumferential side than the outer circumferential edge of the frame (45); the cold storing bodies (30) are mounted on the frame (45) of one retaining member (41) that is disposed in the storage chamber (20), and the frame (45) of the other retaining member (42) is mounted on the top surface of the cold storing bodies (30); and the cold storing bodies (30) are retained between the side wall (20a) of the storage chamber (20) and the support part (46).
