| Abstract(in English) | Nowadays, from battery supplied mobile devices to supercomputers, reducing the power consumption has become a serious design issue. Although using low power supply is the most efficient way to reduce the power, it also increases the leakage power and delay variance. Low-power Electronics Association & Project (LEAP) developed Silicon On Thin Buried Oxide (SOTB) technology in order to solve those problems. Since the SOTB employs fully depleted silicon-on-insulator (FD-SOI) CMOSFET, not only floating-body effects but also variability of threshold voltage due to channel impurity an be suppressed. In order to verify the SOTB technology, we have applied to general-purpose and automotive microcontroller core V850E-Star. In this paper, we demonstrate that SOTB is possible to control the power consumption by applying the substrate bias to the actual chip. Using Dikctra from MiBench embedded benchmark, the power consumption and available clock freqency controlled by the substrate bias voltage were evaluated. From the results, it appears that the bias voltage control to the memory is more effective compared with that to CPU core. |
