This paper presents the power consumption estimation for the novel Virtex architecture. Due to the fact that the XC4000 and the Virtex core architecture are very similar, we used the basic approaches for the XC4000-FPGAs power consumption estimation and extended that method for the new Virtex family. We determined an appropriate technology-dependent power… (More)
This paper presents a new approach to the design of embedded systems. Due to restrictions that state-of-the-art methodologies contain for hardware/software partitioning , we have developed an emulation based method using the facilities of reconfigurable hardware components , like Field Programmable Gate Arrays (FPGA). Our own emulation environment called… (More)
This paper presents the emulation of an embedded system with hard real-time constraints and response times of about 220 /spl mu/s. We show that for such fast reactive systems, the software overhead of a real time operating system becomes a limiting factor. We analyze the influence of novel microcontroller features, e.g., different on-chip caches, which tend… (More)
This paper analyzes the performance of two different real-time operating systems. Therefore, we used a real benchmark embedded system design with fast external reaction times of about 220µs. We show that for such fast re-active systems, the software overhead of a real-time operating system becomes a limiting factor. We analyze the influence of novel… (More)
