1. Getting Started With SHARC Processors 2 55 Evaluation Tools 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 Features e High speed USB 2 0 backward compatible wi
