Is dark silicon useful?: harnessing the four horsemen of the coming dark silicon apocalypse
Due to the breakdown of Dennardian scaling, the percentage of a silicon chip that can switch at full frequency is dropping exponentially with each process generation. This utiliza...

A QoS-aware memory controller for dynamically balancing GPU and CPU bandwidth use in an MPSoC
Diverse IP cores are integrated on a modern system-on-chip and share resources. Off-chip memory bandwidth is often the scarcest resource and requires careful allocation. Two of t...

WCET-centric partial instruction cache locking
Caches play an important role in embedded systems by bridging the performance gap between high speed processors and slow memory. At the same time, caches introduce imprecision in ...

Statistical design and optimization for adaptive post-silicon tuning of MEMS filters
Large-scale process variations can significantly limit the practical utility of microelectro-mechanical systems (MEMS) for RF (radio frequency) applications. In this paper we desc...

Towards fault-tolerant embedded systems with imperfect fault detection
Many state-of-the-art approaches on fault-tolerant system design make the simplifying assumption that all faults are detected within a certain time interval. However, based on a d...

Approaching the theoretical limits of a mesh NoC with a 16-node chip prototype in 45nm SOI
In this paper, we present a case study of our chip prototype of a 16-node 4x4 mesh NoC fabricated in 45nm SOI CMOS that aims to simultaneously optimize energy-latency-throughput f...

Analysis of DC current crowding in through-silicon-vias and its impact on power integrity in 3D ICs
Due to the large geometry of through-silicon-vias (TSVs) and their connections to the power grid, significant current crowding can occur in 3D ICs. Prior works model TSVs and pow...
