Getting Started With SHARC Processors 2-59
The Evaluation Process
This USB-based emulator performs a wide range of emulation functions,
including single-step and full-speed execution with predefined break-
points, and viewing and/or altering of register and memory contents.
With the ability to automatically detect and support multiple I/O volt-
ages, the USB emulator enables users to communicate with all of the
Analog Devices JTAG processors using a full-speed USB 1.1 or high-speed
USB 2.0 port on the host PC. Applications and data can easily be tested
and transferred between the emulator and the separately available Visu-
alDSP++ development and debugging environment.
The plug-and-play architecture of USB allows the emulators to be
detected automatically and configured by the host operating system. The
USB 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 the USB emulator elimi-
nates the need to obtain that help and thus can be easily moved from the
lab to the local desktop to the laptop.
