MuCCRA-Cube is a scalable three dimensional dynamically reconfigurable processor. By stacking multiple dies connected with inductive-coupling links, the number of PE array can be increased so that the required performance is achieved. A prototype chip with 90nm CMOS process consisting of four dies each of which has a 4 × 4 PE array was implemented. The vertical link achieved 7.2Gb/s/chip, and the average execution time is reduced to 31% compared to that using a single chip.
