Project: FIESTA (flexible and energy-efficient embedded systems architecture)

In this research, we tackle application-specific design problems in various embedded system domains. Issues around new solid-state disk (SSD) technology and coarse-grained reconfigurable architecture (CGRA) are of current interest. We are particularly focused on reducing power consumption.
