1A Bridge from User Requirements to Forecasted Embedded Systems Technology

Abstract — The design studies of the embedded systems for future distributed data-processing applications assess the cost and performance of the hardware infrastructure. Spec-ifications are derived from user requirements depending on system architecture; delivery time and enabling forecasted technology. Relating requirements to forecasted technology is complex because these aspects are much intertwined. We bridge the gap for the embedded system technology that are major parts of the next generation radio telescopes, LOFAR and SKA. We were able to take the technology advances into ac-count early in the project. This was possible using hierar-chical and stochastic performance models. Hence we could derive hardware specifications from astronomical applica-tions and assess cost-performance ratio for signal processing scenarios from specifications of forecasted technology
