Figure 1-1 also illustrates how the ADS can be used as an emulator for a defined target
system whose hardware or software the user needs to debug. Here the user must provide
an access point on the target hardware for a 14-pin JTAG/OnCE interface cable, which
may be as simple as a 2-row
×
7-set of test points. Chapter 3, "Functional Description,"
provides complete details of the pinout on the JTAG/OnCE interface cable.
The ADS software program provides routines the user needs to communicate with the
target DSP on the ADM or the target application. This program has a group of powerful
commands that enable the user to perform a variety of tasks. Operating system command
calls may be made from within the program, or temporary exits to the operating system
may be made without disturbing current set-ups with the target DSP.
For more information about the above paragraph, refer to the
ADS User’s Manual
which
can be found on the Development Tools CD included with the kit or at the following web
address:

The Host interface board provides a physical link between the HOST computer and the
Command Converter via a parallel data and control bus cable. The parallel data path is
used for high-speed data transfers. The control bus signals enable the HOST computer to
reset, interrupt, and send commands to Command Converter simultaneously or
sequentially. The command converter then sends the reset, intercept, and various
commands to the ADM via the JTAG/OnCE cable.
The ADM is the basic platform for evaluating the DSP. It contains a DSP chip with a
JTAG/OnCE interface connector to configure it as a slave to the HOST computer or as a
stand-alone unit. In the slave configuration, the user controls the DSP processor and is
able to interrogate its status. This enables the user to debug hardware and software easily.
In the stand-alone configuration, a user program resident in ROM controls the ADM and
may be used as a prototype system for an end product.
1.2 Operating Environment
The ADS hardware and software is currently supported on the following three host
computers:
PC-workstations
Hewlett Packard HP700 workstations
Sun-4 and compatible workstations
