Tailwind(TM) From Blackhawk(TM) Extends Texas Instruments DSP/BIOS(TM) to Support POSIX(R)
DALLAS and MOUNT LAUREL, N.J., Oct 15, 2008 /PRNewswire via COMTEX/ --
Blackhawk(TM), a
leading maker of digital signal processor (DSP) hardware and software
development tools, today announced the availability of Tailwind(TM), a
POSIX-compliant layer for DSP/BIOS(TM) software kernel. Tailwind(TM) supports
Texas Instruments' (TI) TMS320C6000(TM) high performance digital signal
processors (DSP) for applications including high-definition (HD) digital
video, audio and broadband infrastructure.
Tailwind is composed of a comprehensive set of API functions from the
POSIX standard including real-time extensions, threads and core services, such
as process control, signals, timers and file operations. Tailwind's API sits
entirely above the DSP/BIOS kernel providing users with well-defined and
standardized operating system services on which to design reliable and robust
application software. These standardized operating system interfaces enhance
programmers' productivity by encouraging them to comply with proven and
efficient programming practices, which is the core of DoD's mandated Joint
Technical Architecture (JTA) OS Services.
POSIX, or Portable Operating System Interface, is a set of standards
specified under IEEE Std. 1003 and accepted by ISO, IEC and ANSI. These
standards govern how to write application source code so that the applications
are portable between operating systems. The most well-known POSIX standard is
IEEE Std. 1003.1 (ISO Std. 9945), also known as "POSIX.1". POSIX is most
commonly used to provide a standardized programming interface for porting
applications and is well known by today's programmers, especially those
developing general purpose processor (GPP) applications on Linux for the
ARM(R)-based TI devices.
With Blackhawk's Tailwind POSIX-compliant layer, adapting DSP-based
applications to meet today's requirements, such as software communications
architecture (SCA) requirements imposed on software defined radio (SDR), is
now a reality. SDR technology implements dynamically configurable and
upgradable software for application both in commercial products, such as
public safety radios, general radios and walkie-talkies, and in military
applications, such as Joint Tactical Radio Systems (JTRS).
"Blackhawk's Tailwind layer contains all the necessary SCA services
providing a tremendous advantage to SDR applications running on TI DSPs," said
Ram Sathappan, SDR marketing manager at TI. "Developers can also seamlessly
interface to the common object request broker architecture (CORBA), which
permits dissimilar processors, operating systems and networks to interoperate
over a common communications protocol."
Besides providing a complete set of SCA-required POSIX interfaces,
Tailwind(TM) includes numerous other services and capabilities, e.g. timeout
support for blocking functions. All of these services and capabilities are
aimed at supporting source code portability, an increasingly important
requirement for systems that are currently being developed for commercial
applications and government contracts.
Tailwind(TM) supports TI's C6000(TM) DSP platform, which includes the
TMS320C64x(TM) and TMS320C64x+(TM) cores. In addition, Tailwind also supports
Code Composer Studio(TM) (CCStudio) v3.3 integrated development environment
(IDE), C6000 DSP compiler versions 6.0.x and 6.1.x, socket libraries (TI NDK
1.93/1.94) and TMS320C6455 and TMS320C6416 DSP Software Kit (DSK) target
boards.
Pricing and Availability
Available Distributions for Tailwind are:
-- Evaluation (limited runtime)
-- Standard distribution (binaries, link libraries, examples)
-- Full source-code distribution
Tailwind pricing starts at $500 for a fully-functional evaluation, with
standard product options ranging in price from $10,000 to $15,000 depending on
type of distribution and intended end-user licensing. Contact Blackhawk or an
