Most of the MINs proposed in the literature have been constructed with 2x2
crossbar switches as basic elements, and have n = [log.sub.2]N switching stages with each stage consisting of N/2 elements, which makes the cost of this network as O(NlogN), as compared to O([N.sup.2]) for a crossbar [3].
OEM pricing in volumes of 1,000 is $599 for the CX27301 Queue Manager and $599 for the CX27302
Crossbar Switch.
Over time, the speed of the processors and the
crossbar switch has increased, but each node was basically identical to an RS/6000 workstation.
Usually a
crossbar switch is used in the router to connect the input external channels to the output external channels.
Just two months ago, Silicon Graphics introduced the 250 MHz MIPS OCTANE/SSE, a powerful UNIX workstation that features the company's revolutionary
crossbar switch architecture and new high-performance E- Series graphics to deliver exceptional performance on the desktop.
The company's engineers met this challenge by adopting a
crossbar switch that uses advanced packet-switching technology to route messages directly from one processing element of the computer - the central processing unit (CPU) - to another, such as the graphics subsystem.
Tokyo, Dec 14, 2009 - (JCN Newswire) - NEC Corporation, in collaboration with the National Institute of Materials Science (Managing Director: Sukekatsu Ushioda; NIMS), today announced the successful integration of NanoBridge(R)(1), a solid electrolyte(2) non-volatile
crossbar switch, in Cu interconnects placed on CMOS logic(3).
Topics include a buffered
crossbar switch fabric using shared memory, an asynchronous PLA with improved security characteristics, a mixed language simulation of VHDL and SystemC, a RISC processor with redundant LNS instructions, and a cascade scheme for concurrent error detection.
3.9-MHz reference signals were routed from a separate chassis to each mixer via a
crossbar switch.
"The doubling of capacity combined with the high bandwidth of Hitachi's
crossbar switch architecture and virtual storage ports are key differentiators between Hitachi's products and the competition.
