1. 1. Reconfigurable On-Chip Instrument Access Networks : Analysis, Design, Operation, and Application

   Författare :Farrokh Ghani Zadegan; Integrerade elektroniksystem; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; On-chip instruments; reconfigurable networks; access time optimization; retargeting; fault management;

   Sammanfattning : The constant need for higher performance and more advanced functionality has made the design and manufacturing of modern electronic chips highly demanding. Moreover, the use of smaller transistors in modern chips has increased their sensitivity to aging and faults, hence the need to constantly monitor the correct operation of these chips. LÄS MER
