Modern FPGAs have become so affordable that they can be used to substitute ASICs in mass produced devices. A key component of such configurable system on a chip (CSoC) is the processor core. Available and usable cores are either 32 or 8 bit wide. Thus, there is a gap between these two extremes, which we want to fill with our SoC kit. In this contribution we elaborate on our SoC kit and its components...
Modern platform FPGAs integrate fine-grained reconfigurable logic with processor cores and allow the creation of complete configurable systems-on-chip. However, design methodologies have not kept up with the rise in complexity of the target hardware. In particular, there is little overlap between the programming model for embedded software running on a real-time operating system and the programming...
This paper presents a DVS (Dynamic Voltage Scaling) enabled SoC (System-on-Chip) processing platform based on the Leon3 open-source processor and dynamically reconfigurable clock synthesis technology available in Virtex-4 Xilinx FPGAs. A special DVS monitor unit maintains correct operation of the processor core at a given voltage by tracking the behavior of an internal delay line and stopping the...
