The progressive development of new hard- and software applications leads to an increase in the amount of data to be processed and to a constantly rising need in bandwidth. To be able to efficiently process these data more powerful systems of information and communication technologies are needed. The performance of these systems is determined by its individual components and by the bus systems connecting the components. One can foresee that in the future the performance of the systems will be limited by these bus systems. ... <link>For further information look here.
