Energy Efficient Near-Threshold Voltage Massive MIMO Computing

arXiv:2611.06772v1 Announce Type: new Abstract: Near-Threshold Computing (NTC) offers a substan- tial energy savings, i.e., up to 10x, for digital circuits. However, due to Process, Voltage, and Temperature (PVT) variations, low voltage operating digital processors face increased susceptibility to timing errors. This work equips conventional massive MIMO algorithms with computational error detection mechanisms, en- abling reliable operation down to near-threshold voltages. While conventional hardware based Timing Error Detection (TED) systems introduce substantial overhead, this work modifies MIMO algorithms to seamlessly integrate low overhead Algorithm Based Fault Tolerance (ABFT).
