| dc.description.abstract | Communication architectures such as Point-to-Point (P2P) and shared bus are poorly scalable as the number of cores or the communication volume increase. Networkon- Chip (NoC) has been proposed to reduce power consumption and has been widely adopted by the System-on-Chip (SoC) community. Yet, NoCs occupy more area and consume more power as the size of network increases. In this thesis, we propose a novel dynamic reconfigurable P2P (DRP2P) communication architecture for reconfigurable embedded systems, which is an alternative to the conventional NoC architectures. In DRP2P, interconnects are reconfigured on-the-fly as new communication requests arrive at the system. In embedded applications running on the multi-core systems, the traffic flow is usually known. Hence, DRP2P is very suitable for embedded systems. DRP2P is inspired from both P2P interconnects and NoC architecture. If the traffic flow is known in advance, it works as fast as P2P while reconfiguration process is done at the time of computation. Thus, next communication scenario can be established before communication starts. Since the reconfigurable wiring area in DRP2P is proportional to the network size, it is as scalable as NoC. In order to achieve reconfiguration efficiently, we developed three different dedicated self reconfiguration engines. The latest version of these engines is exploited in DRP2P architecture. DRP2P gives better results than conventional NoCs if the physical placement of cores on the embedded system is done properly by utilizing mapping and routing algorithms. Hence, fast and heuristic mapping and routing algorithms are also designed in the scope of this thesis. Experimental evaluations have shown that DRP2P outperforms conventional NoCs even in the worst case scenario as the amount of data in on-chip communication increases. | |
