Figure 1.2 System Configuration with the Emulator (PCI Card Emulator Used)
The emulator provides the following features:
• Excellent cost-performance card emulator
Compactness and low price are implemented using the PCMCIA interface or the PCI interface.
• Realtime emulation
Realtime emulation of the user system is enabled at the maximum operating frequency of the
CPU.
• Excellent operability
Using the Hitachi Debugging Interface (HDI) on the Microsoft® Windows® 98, Microsoft®
Windows® Me, Microsoft® Windows NT®, and Microsoft® Windows® 2000 operating systems
enable user program debugging using a pointing device such as a mouse. The HDI enables
high-speed downloading of load module files.
• Various debugging functions
Various break and trace functions enable efficient debugging. Breakpoints and break
conditions can be set by the specific window, trace information can be displayed on a window,
and command-line functions can be used.
• Memory access during emulation
During emulation, the memory contents can be read and modified.
• Debugging of the user system in the final development stage
The user system can be debugged under conditions similar to the actual application conditions.
• Compact debugging environment
When the card emulator specific to the PCMCIA interface is used, a laptop computer can be
used as a host computer, creating a debugging environment in any place.
