Title: Cache memory which evicts data which has been accessed in preference to data which has not been accessed
Inventor: JONES ANDREW MICHAEL
IPC: G06F12/0888
Filed: 2008-11-18
Abstract: A cache memory 1, for providing rapid access to data from a system memory 105, can identify whether a region has been accessed by an external device, such as a processor 101 or DMA controller 107. When data is loaded into the cache, it is loaded into a region which has been accessed in preference to one which has not. If there are no free regions and no regions that have been accessed, the data may fail to load data into the cache. The loading of data may be a pre-fetch operation. The cache may have a status value for each line in the cache which indicates whether the line has been accessed. The status value may be stored with the address tag. The cache memory may be a level 2 cache.

A stack of superposed sheets of thin metal or foil are diffusion welded at areas defined by patterns of stop weld. Metals such as stainless steel, aluminium or titanium alloy are welded in vacuum or inert gas whereas metals such as copper are welded in air. In making a honeycomb core strips 20 of stainless steel foil are provided on one side with zones 21 of a stop weld based on magnesium oxide and are stacked in an enclosure 10 which is evacuated or filled with inert gas. Pressure is applied to the stack 14 by a hydraulic press 12 and current is passed lengthwise through the strips from conductors 16, 17 to provide resistance heating up to 2100 F. A series of varying pressures are applied as the temperature rises so that the strips 20 bend into the spaces between the zones 21 and contact at pressures to produce diffusion welds 25. The stop weld is subsequently removed in an acid bath and the stack expanded to form a honeycomb. In a modification, a stack of copper strips is heated to 1700 F. by interposing electric heater strip between the stack and the platens of the press. A bellows is manufactured by welding together a stack of sheets coated with areas of stop-weld. After welding, the outer regions of the sheets are trimmed off the centre is bored, the stop weld removed and the stack is expanded to form a bellows.
