Abstract
This article presents a technique titled metastability
condition detection and correction (MEDAC) that is featured in a
near-threshold voltage (NTV) network-on-chip (NoC) hardware.
The proposed technique introduces a double-sampling-based
circuitry to detect whether the input data arrives too close
to the receiver’s clock edge, which is defined as a metasta-
bility condition. The MEDAC also contains a metastability
condition mitigation scheme to monitor if the occurrence of
such metastability con
