Building Block Networks with Wireless Inductive Coupling Though-Chip Interface (Amano)
Inductive Coupling Though-Chip Interface (TCI) connects stacked chips by
coils only with existing IC interconnections. Over-Gb/s data transfer
rate can be achieved with less than 10mW power dissipation. Parallel data bits
can be multiplexed into one single coil and burst-transferred.
With TCI, a high speed network can be formed just by stacking multiple chips
in various forms. A heterogeneous multi-core system called Cube-1 consisting of
an embedded CPU and multiple accelerators is now available.
By using TCI, a building block network, which
has intermediate properties between Network-on-Chips and wireless ad-hoc
networks, is formed by combining chips in various structures.
