The IEEE 1687 (iJTAG) standard introduces an efficient access network based on reconfigurable scan, for accessing the increasing number of embedded instruments. Pattern retargeting is defined as the process of translating an instrument pattern to several network-level scan vectors. In this paper, an efficient structured methodology is presented for performing dynamic pattern retargeting. Dynamic retargeting...
Modern systems-on-chips rely on embedded instruments for testing and debugging, the same instruments could be used for managing the lifetime dependability of the chips. The IEEE 1687 (iJTAG) standard introduces an access network to the instruments based on reconfigurable scan paths. During lifetime, instruments could be required to initiate communication with a system-level dependability manager for...
This paper presents two soft-error mitigation methods for DSP processors. Considering that a DSP processor is composed of several functional units and each functional unit constitutes of a control unit, some registers and combinational logic, a unique characteristic of DSP workloads has been deployed to develop a masking mechanism for the control-logic of each functional unit. Combinational logic...
