Aging-Aware Reliable Multiplier Design With
Adaptive Hold Logic
AbstractโDigital multipliers are among the most critical arithmetic functional
units. The overall performance of these systems depends on the throughput of the
multiplier. Meanwhile, the negative bias temperature instability effect occurs when
a pMOS transistor is under negative bias (Vgs = โVdd), increasing the threshold
voltage of the pMOS transistor, and reducing multiplier speed. A similar
phenomenon, positive biastemperature instability, occurs when an nMOS transistor
is under positive bias. Both effects degrade transistor speed, and in the long term,
the system may fail due to timing violations. Therefore, it is important to design
reliable high-performance multipliers. In this paper, we propose an aging-aware
multiplier design with a novel adaptive hold logic (AHL) circuit. The multiplier is
able to provide higher throughput through the variable latency and can adjust the
AHL circuit to mitigate performance degradation that is due to the aging effect.
Moreover, the proposed architecture can be applied to a column- or row-bypassing
multiplier. The experimental results show that our proposed architecture with 16
ร16 and 32 ร32 column-bypassing multipliers can attain up to 62.88% and 76.28%
performance improvement, respectively, compared with 16ร16 and 32ร32 fixed-
latency column-bypassing multipliers. Furthermore, our proposed architecture with
16 ร 16 and 32 ร 32 row-bypassing multipliers can achieve up to 80.17% and
69.40% performance improvement as compared with 16ร16 and 32 ร 32 fixed-
latency row-bypassing multipliers.
