| Outline of Final Research Achievements |
To realize advanced IoT systems, active and advanced signal processing on sensor nodes is required, while flexibility is needed to support various applications. In this project, we clarify the highly efficient implementation of signal processing required for the wireless communications and the methodology for transmitting high-quality video images with high energy efficiency with coarse-grained reconfigurable devices. Based on these results, the structure (architecture) of the reconfigurable architecture suitable for the target system has been explored.
