By shortening communication distance across dies, 3D technologies are a key to continued improvements in computing density. For 4G telecom baseband processing, specific computing units arranged in a regular network-on-chip (NoC) array provide power-efficient computation [1]. However, for advanced MIMO processing, more computing power is required when the number of antennas increases. This paper presents a homogeneous 3D circuit composed of regular tiles assembled using a 4x4x2 network-on-chip, using robust and fault tolerant asynchronous 3D links, providing 326MFlit/s @ 0.66pJ/b, fabricated in CMOS 65nm technology using 1980 TSVs in a Face2Back configuration.
