POSTER: computer news   ||   ARCTIC COOLING FREEZER 64 LP	DATE:2007-03-01
The new model of processor cooler with the air type of cooling presented the company arctic cooling. Freezer 64 LP has sufficiently uncommon construction, it is characterized by low profile and high performance. This cooling device  is positioned by producer as high performance cooler for AMD processors sempron, Athlon 64, Athlon 64 X2, Athlon 64 FX Opteron  socket 939 and AM2. Freezer 64 LP consists of two fans, three thermal tubes and specially designed low-profile radiator. It is characterized by the low level of noise, it will be well suited for assembling of low-profile low-noise PC of small form factor (for example, SFF HTPC). The cooling unit freezer 64 LP works on cooling not only processor, but also of located next to it components: the load-bearing elements of power, chipset and other. To Arctic cooling freezer 64 LP, which costs 24 dollars ; the guarantee of the producer 6 years is extended. Arctic cooling freezer 64 LP	Add Comment ( 0 ) ARCTIC COOLING FREEZER 64 LP

The Japanese company buffalo continues to release uncommon manipulators of type mouse for PC. At this time by originality must flash the model BOMU-JK/M, which instead of the customary layout, — of two keys and little wheel of warming up has instead of scroll  button with four degrees of freedom as on the play manipulator joystick, by which the play video attachments and consoles are usually completed. However, in the difference from the play manipulators, this device, according to the intention of the engineers company, to called introduce additional comfort with the work with the office applications and the documents of the large sizes, which because of this mouse can be will be conveniently turned over the pages not is only horizontally, but also is vertical. A series BOMU-JK/M consists in all two models, the only difference between which is the color . The model BOMU-JK/MSV has silver color, and BOMU-JK/OF MBK come with black. Remaining characteristics of both mouse are identical: the type of connection is USB, the optical sensor is 800 dpi, the cost is 27,5 dollars. The beginning of sales is planned for the middle of this month. mouse BOMU-JK-M	Add Comment ( 0 ) MOUSE BOMU-JK-M

As it became known, the company tundra semiconductor, which represented a certain time the back asynchronous bridge PCI-to-PCI with the lowered energy consumption, already beginning its series output. Asynchronous, 32-bit, 66- MHz the bridge tsi350 completely satisfies the specifications PCI local bus specification revision 2.3. On the arrangement of conclusions and program model it is compatible with other microcircuits of bridges PCI-to-PCI, utilized today. At the same time, new product is characterized by the lowered energy consumption. It support two system buses PCI, which work simultaneously, and quantity of conclusions is sufficient in order to connect nine devices (PCI bus master device) directly to the second interface. Thus, Tsi350 gives the possibility to enlarge the load-carrying capacity of system beyond the limits, assigned in the case of only system bus PCI, and is opened before the developers the way of adding additional devices and expansion card  PCI. The microcircuit tsi350 is released in the 208- contact case of type PQFP by sizes 31 X 31 mm. As it is evident, despite the assurances of analysts relative to the complete victory PCI express, producers do not hurry to copy from the calculations system bus PCI.

POSTER: computer news   ||   RESTORATION OF LOGICAL BIS	DATE:2007-03-01
The specialists of corporations NEC and NEC electronics together developed the technology, which ensures the possibility of independent restoration of logical BIS (large-scale integrated circuits, LSI) even during repeated damages, which arose already after delivery, as a result aging microcircuits. Although the similar technology already adapts in BIS memory, which have regular structure, it is much less extended in logical BIS. Technology includes two aspects. One of them is connected with solution of problem detecting the failures, and another is  technique of the reserve chains, which are set in operation in the case of troubles. The detection of failures is based on the replacement of standard triggers by the special, which can recognize worsening on a increase in delays. When delay exceeds the previously predetermined value, is done the conclusion that malfunction, caused by aging microcircuit, occurs, and switching to the reserve chain is excuted out. Reserve chains are formed due to the separation of initial into smaller blocks and duplicating of each such blocks. Today, the majority of logical BIS contains the reserve copies only of comparatively large blocks of – of such, as processor cores. Certainly, in this case, probability that the defects, which arose two large units of one and the same chip, they will lead to its failure, it is completely high. Separation in smaller blocks makes possible to go around this problem : even repeated failures in this case they can be removed by switching the corresponding sections to the reserve chains. restoration of logical BIS	Add Comment ( 0 ) RESTORATION OF LOGICAL BIS
