DSP Selection Guide 11

VisualDSP++

The IDE allows access to the DSP C/C++

compiler, C/C++ runtime library, assembler,

linker, loader, and splitter. Specification of

options for these tools is made possible through

the property page dialogs. Property page

dialogs are easy to use and simplify

configuring, changing, and managing projects.

These options may be defined once and then

modified to meet changing development needs.

The DSP code generation tools can be accessed

from the operating system command line.

Greatly Reduced Debugging Time

The VisualDSP++ debugger has an easy-to-use,

common interface to all DSP simulators and

emulators available through Analog Devices,

Inc. (ADI) and from many third party partners.

The debugger has many features that greatly

reduce debugging time. C/C++ source can be

viewed interspersed with the resulting assembly

code. Users can profile execution of a range of

instructions in a program; set watch points on

hardware and software registers, program and

data memory; and trace instruction execution

and memory accesses. These features enable

users to correct coding errors, identify

bottlenecks, and examine DSP performance.

The custom register option allows developers

to select any combination of registers to view

in a single window. The debugger, when used

with the simulator, can also generate inputs,

outputs, and interrupts to simulate real world

application conditions. With C++, developers

can realize a significant increase in time to

market with the ability to efficiently work with

complex signal processing data types and take

advantage of specialized DSP operations

without having to understand the underlying

DSP architecture.

VisualDSP++ simplifies DSP development via

common development environment across all

Analog Devices hardware and DSPs.

VisualDSP++ Kernel

The VisualDSP++ Kernel (VDK) provides

state-of-the-art scheduling and resource

allocation techniques tailored specifically to

address the memory and timing constraints of

DSP programming. These techniques enable

engineers to use example code more efficiently,

eliminating the need to start from the very

beginning. The VDK has standard libraries and

frameworks with defined APIs that allow easy

inclusion of boilerplate, class libraries and

value-added IP code.

ActiveX

ActiveX allows new functionality to be added

by developers and third parties to VisualDSP++

in the form of “plug-ins” that integrate into the

VisualDSP++ environment. Third parties will

be able to seamlessly port their software to

VisualDSP++’s front-end. Developers will be

able to merge tool suites together to improve

design, analysis and verification thus they will

only need to learn one interface to use ADI

third party tools.

Multiprocessing Support

VisualDSP++’s smart multiprocessor (MP)

debug support provides a seamless interface to

multiple DSPs on the same physical hardware.

Users are able to issue parallel step, run, and

halt commands to all of the applicable DSPs.

The developer can pick and choose individual

DSP register or memory sets of interest by

pinning those that should be updated between

runs, halts and steps. This feature also

eliminates screen clutter in multiprocessor

debugging.
