COFF object code generated from the Linker/Locator. The simulator allows verification
and monitoring of the DSP states without the requirement of the DSP hardware. Besides
a windowed mouse driven interface which can be user-customized it also contains a high
level language debug interface. To simulate external signals or hardware logic, it is
possible to connect DOS files and integrate C functions using the Dynamic Link Library
(DLL) mechanism of WINDOWS. During program execution, the internal registers and
memory of the simulated DSP are modified as each instruction is interpreted by the host.
Execution is suspended when either a breakpoint or an error is encountered or when the
user halts execution. Then the DSP internal registers and both program and data
memory can be inspected and modified.

Siemens provides a development board which can be used for a quick start for a new
project; to develop software, test interfaces, memory configuration, critical ICs, etc. Both,
the Microprocessor and the DSP can be controlled at a time via two different serial
interfaces, Figure 9-11.

Thus the software development engineers can interactively read from and write to all
DOC registers.
The DOC evaluation board, Figure 9-12, implements the full hardware functionality of a
small PBX and supports many features of the DOC within an INTEL 386EX based
microprocessor system enviroment. With the DOC board Siemens will also offer a PBX
orientedand basic software modules.
