Context saving and restoring for multitasking in reconfigurable systems
H. Kalte,Mario Porrmann +1 more
TL;DR: This paper discusses ways to save and restore the state information of a hardware task, and significantly reduces the amount of readback data by reading only those configuration frames that contain state information.
Proceedings ArticleDOI
REPLICA: a bitstream manipulation filter for module relocation in partial reconfigurable systems
TL;DR: The REPLICA (relocation per online configuration alteration) filter is developed, which is capable of performing the necessary bitstream manipulations during the regular download process and enables the integration of dynamic systems that can be adapted to changing demands during runtime.
Journal ArticleDOI
A 65 nm 32 b Subthreshold Processor With 9T Multi-Vt SRAM and Adaptive Supply Voltage Control
Sven Lütkemeier,Thorsten Jungeblut,Hans Kristian Otnes Berge,Snorre Aunet,Mario Porrmann,Ulrich Rückert +5 more
TL;DR: An energy-efficient SoC with 32 b subthreshold RISC processor cores, 32 kB conventional cache memory, and 9T ultra-low voltage SRAM based on a flexible and extensible architecture that provides dynamic voltage and frequency scaling (DVFS) combined with an adaptive supply voltage generation for dynamic PVT compensation is fabricated.
Proceedings ArticleDOI
REPLICA2Pro: task relocation by bitstream manipulation in virtex-II/Pro FPGAs
H. Kalte,Mario Porrmann +1 more
TL;DR: The REPLICA2Pro (Relocation per online Configuration Alteration in Virtex-2/-Pro) filter is developed, which is capable of performing task relocations by manipulating the task's bitstream during the regular allocation process without any extra time overhead.
Journal ArticleDOI
Coherent optical communication: towards realtime systems at 40 Gbit/s and beyond.
TL;DR: The results of a realtime QPSK transmission system with a 3x3 coupler in the receiver are presented, with the achieved BER at a data rate of 1.4 Gbit/s is well below the FEC threshold.
