Partial core encryption for performance-efficient test of SOCs

O. Sinanoglu, A. Orailoglu
2003 ICCAD-2003. International Conference on Computer Aided Design (IEEE Cat. No.03CH37486)  
The isolation of a core through full I/O scan helps ease SOC test challenges; yet the performance of high-speed SOCs is significantly hampered.  ...  Once the partially encrypted cores are merged into an SOC, the system integrator performs test generation on the visible SOC logic only, greatly reducing the test generation effort expended.  ...  The partial isolation ring technique in [2] proposes the scan of a subset of core I/Os.  ...

Concept of Embedded Dipoles as a Versatile Tool for Surface Engineering

Egbert Zojer, Andreas Terfort, Michael Zharnikov
2022 Accounts of Chemical Research  
In molecular and monolayer electronics, embedded-dipole SAMs can be used to control transition voltages and current rectification.  ...  By varying the orientation of the embedded dipolar moieties, it is also possible to build p- and n-type organic transistors using the same electrode materials (Au).  ...  The dominant peak corresponds to the core-level excitations for C atoms in the top ring; its position is shifted electrostatically by the embedded dipoles.  ...

Asmaa Tellabi, Christoph Ruland, Karl Waedt, Abdelbast Sabri
2019 Journal of Communications Software and Systems  
In the embedded systems´ world, virtualization has been a rising trend, essentially because it offers an isolation mechanism that provides hardware manufacturer´ independence and it avoids obsolescence  ...  For this implementation a type 1 hypervisor called Xtratum is used.  ...  Based on separation kernels, the system´s security is realized partially by physically isolating different modules and managing trusted functions which are executed within some modules.  ...
