2-56 Getting Started With SHARC Processors
These easy-to-use USB-based emulators perform a wide range of emula-
tion functions, including single-step and full-speed execution with
predefined breakpoints, and viewing and/or altering of register and
memory contents. With the ability to automatically detect and support
multiple I/O voltages, the HP-USB emulator enables you to communicate
with all of the Analog Devices JTAG processors using a full-speed
USB 1.0 or high-speed USB 2.0 port on the host PC.
Applications and data can be tested and transferred easily (and rapidly,
when the HP-USB emulator is connected to a high-speed USB 2.0 port on
your host PC) between the emulators and the separately available Visu-
alDSP++ development and debugging environment.
The plug-and-play architecture of USB allows the emulators to be auto-
matically detected and configured by the host operating system. It can also
be connected to (and disconnected from) the host without opening the PC
or turning off the power to the PC. A 3-meter (9-foot) cable is included to
connect the emulators to the host PC, thus providing abundant
accessibility.
As a bonus, customers in an environment that does not allow them to
open their PCs without IS support will find that both emulators eliminate
the need to obtain that help and thus can be easily moved from the lab to
the local desktop to the laptop.
