摘要： A method for maintaining cache coherency while minimizing the power consumption. The method includes operating a first processor in a reduced power mode. While the first processor is operating in a reduced power mode, certain portions of the internal logic in the first processor remain clocked so that the first processor continues to monitor transactions on the system bus. The second processor runs a transaction on the system bus to request data. In the event that the first processor determines that the transaction by the second processor is requesting cache data that is stored in the first processor in a modified state, the first processor signals the second processor. After the current bus cycle is completed, the first processor writes back the modified cache line on the system bus and second processor re-runs the transaction on the system bus.

摘要： Disclosed anti-ram systems comprise at least one bollard section comprising a base of limited height and a plurality of spaced bollards extending upwardly from the base, which may be erected or installed on a paved surface such as asphalt, concrete, paver stones, etc., or on an unpaved surface such as soil, and need not be partially of fully buried, and yet can qualify for Department of State crash ratings previously assigned to buried bollard systems. Disclosed anti-ram systems also comprise a plurality of bollard sections and one or more connectors for interconnecting two or more of the bollard sections, and may also include an anchor or anchor system engaging at least each end of a bollard section not connected to another bollard section. The bollard sections may be filled with ballast and high friction structure may be attached to the bottom of the bollard sections to resist sliding after impact.
