Post-silicon validation is a critical part of integrated circuit design methodology. The primary objective is to detect and eliminate the bugs that has escaped pre-silicon validation phase. One of the key challenges in post-silicon validation is the limited observability of internal signals in manufactured chips. Leveraging on-chip buffers addresses this(More)
A key problem in post-silicon validation is to identify a small set of traceable signals that are effective for debug during silicon execution. Most signal selection techniques rely on a metric based on circuit structure. Simulation-based signal selection is promising but have major drawbacks in computation overhead and restoration quality. In this paper ,(More)
A key problem in post-silicon validation is to identify a small set of traceable signals that are effective for debug during silicon execution. Structural analysis used by traditional signal selection techniques leads to poor restoration quality. In contrast, simulation-based selection techniques provide superior restorability but incur significant(More)
Optimization techniques are widely used in embedded systems design to improve overall area, performance and energy requirements. Dynamic cache reconfiguration is very effective to reduce energy consumption of cache subsystems which accounts for about half of the total energy consumption in embedded systems. Various studies have shown that code compression(More)

— Estimation of peak power consumption is an essential task in order to design reliable systems. Optimistic design choices can make the circuit unreliable and vulnerable to power attacks, whereas pessimistic design can lead to unacceptable design overhead. The power virus problem is defined as finding input patterns that can maximize switching activity(More)

Memory-based computing (MBC) is promising for improving performance and energy efficiency in both data- and compute-intensive applications. In this paper, we propose a novel reconfigurable MBC framework for multicore architectures where each core uses caches for computation using Look Up Tables (LUTs). Experimental results demonstrate that on-demand(More)
Code encryption is a promising approach that encrypts the application binary to protect it from reverse engineering and tampering, and decrypts the instructions during runtime. A major challenge is to trade-off between the security level and runtime decryption overhead. In this paper, we explore a synergistic combination of various code compression(More)
