A compiler’s overriding mission is to produce correct code, so there
are occasions when the compiler must take a conservative approach
to a code sequence when a more aggressive approach could have
been taken if certain constraints could be guaranteed by the
programmer. The VisualDSP++ compiler supports a broad range of
pragma that allow the programmer to better exploit the compiler
while maintaining C language neutrality. Just as important, the
compiler has the ability to feed back advisory information to the
programmer, offering further improvements to a code sequence should
the programmer be able to make certain guarantees about it. This
information is displayed seamlessly in the VisualDSP++ main editor
window. This “lifts the veil” off the “black box” that compilers are often,
and accurately, accused of being.
Backing the compiler is a powerful assembler and linker technology.
Analog Devices’ processors are noted for their intuitive algebraic
assembly language syntax, and the VisualDSP++ assembler extends that
ease of use with the ability to import C header files, allowing for symbolic
references into arbitrarily complex C data structures. Binary data can
be “included” directly into assembly source files, creating an easy way
to add blocks of static data (such as audio samples and bitmaps) to an
application. The VisualDSP++ linker is fully multicore and multiprocessor
(MP) aware, allowing for the creation of cross-linked, multiexecutable
applications in a single pass. Other powerful capabilities of the linker
include dead code and data elimination, code and data overlays, section
spilling (i.e., automatic overflow from internal to external memory), and
automatic short-to-long call expansion.
Leverage Proven Application Infrastructure
VisualDSP++ goes beyond robust code generation tools, providing
considerable application infrastructure and middleware out of the box
to speed application development. The VisualDSP++ kernel (VDK) is a
robust, royalty-free, real-time operating system (RTOS) kernel. It provides
essential kernel features in a minimal footprint. Features include a fully
preemptive scheduler (time slicing and cooperative scheduling are also
supported), thread creation, semaphores, interrupt management, inter-
thread messaging, events, and memory management (memory pools
and multiple heaps). In MP environments, MP messaging is also
provided. Configuration of these elements is done graphically with code
wizards to speed the creation of new threads and interrupt handlers.
VDK has been available for multiple releases of VisualDSP++ and is now
a key component of products shipping from a number of high volume
vendors. Several commercial RTOSs are also available from select Analog
Devices third parties.
Blackfin Processors can take advantage of the system service library
(SSL), which provides consistent, easy C language access to Blackfin
features such as the interrupt manager, direct memory access (DMA),
and power management units. Clock frequency and voltage can be
changed easily at run time through a set of simple APIs. Interrupt
handling can be live, fired at the time of the event, or deferred to a later
time of the application’s choosing. A device manager integrates device
drivers for on- and off-chip peripherals. VisualDSP++ includes ever
expanding device driver support for all on-chip peripherals and off-chip
devices found on Analog Devices EZ-KIT Lite and EZ-Extender
The SSL is OS-neutral and can be run as a standalone or in conjunction
with an RTOS.

products.
Built upon the system service library, the file system service (FSS)
provides a portable and extensible means of accessing mass
storage media from the Blackfin Processor. Support for the
ADSP-BF548 EZ-KIT Lite development board is provided with
VisualDSP++ 5.0 for FAT file systems on the attached hard disk
drive, supplied SD card, and USB flash.
As embedded applications become increasingly part of the connected
world, the ability to rapidly add reliable Ethernet or USB connectivity
to an application can often make or break a development schedule.
For Blackfin Processors, VisualDSP++ includes a tuned port of the
open source LwIP TCP/IP stack. An example application showcasing
an embedded Web server is among the highlights of this support. For
Blackfin Processors and SHARC Processors, USB 2.0 device connectivity
is provided. Bulk and asynchronous transfer modes are supported out
of the box, with USB-IF logo certified embedded and host applications
provided with full source code.
Wrapping all of these powerful tools and libraries together is the
VisualDSP++ state-of-the-art integrated development and debugging
environment (IDDE). The IDDE includes full-featured editing and project
manage-ment tools with incremental builds, multiple build configurations
(“Debug” and “Release,” for example), syntax-coloring editor, and many
other code editing features. Makefiles can be imported and exported
freely. For Blackfin Processors, many application attributes can be
configured graphically, enabling point-and-click access to SDRAM setup,
stack and heap placement, power management, clock speed, cache
setup, and more.
Debug and Tune Your Application with Ease
The ability to develop a high performance application is often gated
by the visibility into your running system that your debugger provides.
VisualDSP++ excels in this regard, with best-in-class debugging and
inspection support. Robust fundamental C language source debugging
(source-level stepping and breakpoints, stack unwinds, local variable
and C expression support, memory and register windows) serves as a
foundation upon which multiple innovative and unique tools rest.
VisualDSP++ supports a variety of debugging targets. Most common is
a JTAG connection to an EZ-KIT Lite board or to a custom target board
by means of Analog Devices emulator products. However, there will be
Source code generation.
