Technical trends in high-end embedded microprocessors, such as higher frequencies, customization, smaller packages, and internal cache, make traditional in-circuit emulation difficult. Working with Toshiba, Keysight co-developed a on-chip debug monitor. The Keysight processor probe utilizes this technology to provide support for software debug. The processor probe provides a real-time development environment for the high-speed Toshiba-R3900 embedded MIPS processor series.

What Is the Processor Probe? The processor probe provides much of the capability software engineers need to perform in-target debugging at a much lower cost than a traditional emulator. A benefit to using the on-chip monitor is that the microprocessor does not need to be replaced. Access to the target system is gained using the eight pins dedicated to debugging.
