Characterization
Profile the memory demands of neural network layers and accelerator types. Measure how a sensing application responds as other workloads execute.
Memory systems and security
Mem-Clash
Shared memory related security challenges in mobile computing platforms.
Processors on a mobile system on chip often share the same DRAM. When applications compete for memory bandwidth, the resulting slowdown can reveal information about other workloads.
Measuring contention and leakage
The project studies how applications observe memory demand across accelerators, what those observations reveal, and how a system can reduce leakage.
Attack analysis
Examine whether contention signatures reveal network properties or enable communication between otherwise isolated workloads. MC3 studies a covert channel based on shared DRAM contention.
Countermeasures
Investigate memory controller policies and randomization methods that obscure contention signatures, while considering the performance cost.
