Self-optimization of MPSoCs Targeting Resource Efficiency and Fault Tolerance
Mario Porrmann, Madhura Purnaprajna, Christoph Puttmann · 2009
A dynamically reconfigurable on-chip multiprocessor architecture is presented, which can be adapted to changing application demands and to faults detected at run-time. The scalable architecture comprises lightweight embedded RISC processors that are interconnected by a hierarchical network-on-chip (NoC). Reconfigurability is integrated into the processors as well as into the NoC with minimal area and performance overhead. Adaptability of the architecture relies on a self-optimizing reconfiguration of the MPSoC at run-time. The resource-efficiency of the proposed architecture is analyzed based on FPGA and ASIC prototypes.
