Emerging on-ship debugging techniques for real-time embedded systems

The increased clock frequencies and higher integration levels of today´s high-performance embedded microcontrollers have led to the widespread incorporation of on-chip debugging logic into new microcontroller chip designs. The newly defined standard for embedded system debugging, the IEEE-ISTO Nexus 5001 Forum Standard for a Global Embedded Debug Interface, is introduced and is related to the test and debugging requirements of development engineers.
