| Abstract(in English) | Cool mega array (CMA) is a low power coarse-grained reconfigurable accelerator developed using silicon on thin BOX (SOTB). It's a chip for mounting in wearable devices and IoT which has been developed recently. This time, we report on implementation and evaluation of CMA-Cube-SOTB 2 (CC-SOTB2) which is a new version of CMA developed for 3D stacked chip. CMA architecture consists of a large scale processing element (PE) array, a microcontroller for managing data transfer, and a data memory. In CC-SOTB2, power consumption was reduced by optimizing the direct link connecting each PE. We also implemented a variable pipeline in the PE array. This realized performance optimization and reduction of extra power consumption by glitch propagation. As a result, the power efficiency improved by 18% compared with the previous version CC-SOTB. |
