PPT-Multiprocessors Interconnection Networks

An interconnection network could be either static or dynamic Connections in a static network are fixed links while connections in a dynamic network are established on the fly as needed A topologybased taxonomy for interconnection . e a circuit Pumps packet bits nonstop to destination No intermediate buffer Requires setup and teardown time Multicomputer Network Interface Interface boards usually contain buffer for packets Needs to control flow onto interconnection network when s 142 brPage 2br Taxonomy SISD single instruction and sing le data stream uniprocessor MISD no commercial multiprocessor imagine data going through a pipeline of execution engines SIMD vector architectures lower flexibility MIMD most multiprocessors to .

Multiprocessing.  is the use of two or more . central processing units.  (CPUs) within a single . computer . system. . The . term also refers to the ability of a system to support more than one processor and/or the ability to allocate tasks between them. The performance of Interconnection network is measured on the following . parameters:. Bandwidth: . I. t is a measure of maximum transfer rate between two nodes. It is measured in Megabytes per second or Gigabytes per second.. NGN. V.K. Agarwal, Dy. Advisor. Telecom Regulatory Authority of India (TRAI). 7/16/2010. TRAI. 2. Present Telecom Scenario.
