Hi, I am trying to determine the amount of cycles/time required to transfer an Mpacket from an IXF 440 to RFIFO. I have loaded and examined the receive code from chapter 5 in the IXP 1200 book. The history window however displays the information from the microengine point of view. I am interested from both the IXF 440 and RBS point of view the amount of cycles each unit utilises to accomplish this task. Any suggestions as to how I can view this information on workbench would be appreciated. Regards Liam University of Limerick Ireland
