    Hardware-assisted watchpoint systems enhance the execution of numerous dynamic software techniques, such as memory protection, module isolation, deterministic execution, and data race detection. In this paper, we show ...

  • Improving the performance and energy-efficiency of virtual memory 

    Karakostas, Vasileios (Universitat Politècnica de Catalunya, 2016-04-18)
    Doctoral thesis
    Open Access
    Virtual memory improves programmer productivity, enhances process security, and increases memory utilization. However, virtual memory requires an address translation from the virtual to the physical address space on every ...

  • NEMsCAM: A novel CAM cell based on nano-electro-mechanical switch and CMOS for energy efficient TLBs 

    Seyedi, Azam; Karakostas, Vasileios; Cosemans, Stefan; Cristal, Adrian; Nemirovsky, Mario; Unsal, Osman (Institute of Electrical and Electronics Engineers (IEEE), 2015-07-10)
    Conference report
    Open Access
    In this paper we propose a novel Content Addressable Memory (CAM) cell, NEMsCAM, based on both Nano-electro-mechanical (NEM) switches and CMOS technologies. The memory component of the proposed CAM cell is designed with ...
