Gol 4 , A. Nafalski 4 </li></ul><ul><li>1 Faculdade de Engenharia (DEEC), Porto, Portugal </li></ul><ul><li>2 Buskerud College of Engineering, Kongsberg, Norway </li></ul><ul><li>3 INESC Porto, Portugal </li></ul><ul><ul><li>4 University of South Australia, Adelaide, AUSTRALIA </li></ul></ul>Stockholm, Sweden:: 2009 June 29 - July 2 These slides are available at http://www.slideshare.net/josemmf
  2. 2. Introduction and motivation <ul><li>Standardisation trends address high-end solutions </li></ul><ul><li>Embedded internet modules offer low-cost alternatives with increasing performance </li></ul><ul><li>Previous workbenches based on low-cost modules proved to be feasible </li></ul>
  3. 3. The IEEE 1149.1 boundary-scan test standard TDI TMS TCK TDO core circuitry core circuitry core circuitry 001010… 001010… Serial input Parallel input Parallel output Serial output mux mux C/S L
  4. 4. The remote IEEE 1149.1 boundary-scan test workbench TDI TMS TCK TDO core circuitry core circuitry core circuitry Boundary-scan board (experiment hardware) 001010… 001010… Internet IP camera AP7000 Base Linux board 10/100 Mbps Ethernet Experiment interface board
  5. 5. The remote microcontroller workbench Microcontroller board (experiment hardware) Digital I/O Digital I/O Internet IP camera AP7000 Base Linux board 10/100 Mbps Ethernet Experiment interface board
  6. 6. Client view (remote microcontroller workbench)
  7. 7. Client view (remote boundary-scan test workbench)
  8. 8. Conclusion <ul><li>Client and server code for the two workbenches is available as open source modules from Google code </li></ul><ul><li>Performance is far superior to our previous solution based on Maxim-Dallas TINI ® network microcontrollers at ≈ same cost </li></ul><ul><li>The same AP7000 Base board can run multiple experiments simultaneously </li></ul>
