“…The controllers by Lee et al [2005] and Sonics [2005;Weber 2001] are most similar to the FlexWAFE controller. A detailed study dealing with various memory controllers and their properties can be found in Heithecker et al [2007]. Regarding digital image processing, target platforms other than FPGAs are feasible.…”

The challenges posed by complex real-time digital image processing at high resolutions cannot be met by current state-of-the-art general-purpose or DSP processors, due to the lack of processing power. On the other hand, large arrays of FPGA-based accelerators are too inefficient to cover the needs of cost sensitive professional markets. We present a new architecture composed of a network of configurable flexible weakly programmable processing elements, Flexible Weakly programmable Advanced Film Engine (FlexWAFE). This architecture delivers both programmability and high efficiency when implemented on an FPGA basis. We demonstrate these claims using a professional next-generation noise reducer with more than 170G image operations/s at 80% FPGA area utilization on four Virtex II-Pro FPGAs. This article will focus on the FlexWAFE architecture principle and implementation on a PCI-Express board.

Round-Robin scheduling is the most popular time triggered scheduling policy, and has been widely used in communication networks for the last decades. It is an efficient scheduling technique for integration of unrelated system parts, but the worst-case timing depends on the system properties in a very complex way. The existing works on response time analysis of task scheduled under RoundRobin determine very pessimistic response time bounds, without considering in detail the interactions between tasks. This may lead to a degradation of the efficiency of Round-Robin scheduling algorithm, and becomes a practical obstacle to its application in realtime systems. In this paper we present an approach to compute much tighter best-case and worst-case response time bounds of tasks scheduled under preemptive Round-Robin, including also the effects of the scheduling algorithm.
