20110302367 | Write Buffer for Improved DRAM Write Access Patterns - The present invention relates to a method and respective system for operating a DRAM main memory. One buffer line is provided for multiple pages. When writing data to the buffer it is decided which to which buffer-line the data is written to based on its destination main memory address. A tuple consisting of lower memory address and data is stored. Data entered into the buffer-line will be sorted by page in case the line is flushed to the main memory. Sorting the buffer entries results in less page openings and closings, since the data is re-arranged by memory address and therefore in logical order. By using one line for multiple pages only a fraction of memory of a common set-associative cache is needed, thus decreasing the amount of overhead significantly. | 12-08-2011 |
20120158774 | Computing Intersection of Sets of Numbers - The present invention relates to a computer program product, method and system for computing set intersection of a first and a second unordered set of discrete members that stem from a known input range of consecutive discrete numbers. The method breaks the numbers into subranges and for each subrange, utilizes a bit vector in a first random access memory, directly addressing bits representing values in a subrange in the first set to values in the second set in the subrange and writing each number of the second set that is also set member of the first set in the sub range directly to an output. This may be utilized by various applications including database applications. The algorithm may be offloaded to one or more processing subsystems. | 06-21-2012 |

20080314030 | Method for Operating a Nitrogen Oxide Storage Catalytic Converter in a Motor Vechicle with Consideration of Regional Fuel Qualities - The fuel qualities for vehicles differ, for example, in Europe on a regional basis. This applies in particular to the sulphur content of the fuel. If vehicles with modern lean engines or with diesel engines which are equipped with nitrogen oxide storage-type catalytic converters in order to reduce the nitrogen oxide content in their exhaust gas pass through regions with a sulphur content in the fuel which is above the sulphur content which is specified for the vehicle, the engine controller will correspondingly frequently initiate desulphurization of the storage-type catalytic converter after the vehicle has been refuelled with this fuel. Any desulphurization entails an increased level of fuel consumption and greater ageing of the catalytic converter. It is proposed to avoid these adverse effects in that in lean motors the engine controller switches to stoichiometric operation in such a case, and in a diesel engine said engine controller prevents the desulphurization. The information about the region in which the vehicle is moving at a particular time can be transmitted to the engine controller by a navigation system. | 12-25-2008 |
20090297415 | Method For Operating A Nitrogen Oxide Storage Catalyst In A Diesel Engine - A nitrogen oxide storage catalytic converter which is operated for a relatively long time at low exhaust-gas temperatures in the range between 120 and 250° C. exhibits a decreasing storage capacity as a result of incomplete regeneration at said temperatures. In order to re-establish the original storage capacity of the catalytic converter which is operated in this way, two-stage regeneration is proposed, wherein the storage catalytic converter is initially partially regenerated at the low exhaust gas temperature by means of a switch from the lean mode to the rich mode, and wherein subsequently, with rich exhaust gas again, the exhaust-gas temperature of the engine is raised into a range of between 300 and 400° C. for complete regeneration. | 12-03-2009 |
20100055012 | NITROGEN OXIDE STORAGE CATALYST FEATURING A REDUCED DESULFURIZATION TEMPERATURE - Nitrogen oxide storage catalysts are used to remove nitrogen oxides from the exhaust gas of internal combustion engines operated predominantly under lean burn conditions. When these catalysts are used in diesel vehicles, the increased sulfur content in the fuel during operation results in poisoning of the catalyst, which is reversible at high temperatures under reduced exhaust gas conditions. In the case of conventional nitrogen oxide storage catalysts, temperatures of more than 600° C. have to be obtained for desulfurization. This is not always possible in diesel vehicles with a nitrogen oxide storage catalyst in the underbody area. | 03-04-2010 |
