Quadros Systems Announces Multiprocessing RTOS
Support for Texas Instruments’ OMAP™5912
RTXC/mp real-time operating system simplifies development with a
common API and the ability to distribute kernel objects across both
cores
Booth # 411
ARM Developers' Conference, SANTA CLARA, CA - October 19, 2004 -
Quadros Systems, Inc., a leading supplier of configurable and scaleable
real-time operating systems (RTOS), today announced the availability of
its distributed, asymmetric multiprocessing RTXC/mp RTOS for the TI
OMAP5912 dual-core processor. Architectures such as OMAP have become
popular in mobile communications applications, like 3G wireless
telephony, that support both high data rate voice and data processing
while delivering powerful user features such as web browsing, text
messaging, personal information management and gaming. With the RTXC/mp
RTOS, developers can achieve greater programming efficiency while
minimizing development complexity.
OMAP is a dual-core, heterogeneous processor that combines a powerful
ARM™-based 32-bit RISC core for control processing with a
high-performance 16-bit integer TI DSP core for signal processing. Until
now, the lack of unified software for heterogeneous processors has
forced developers to use different operating systems on each OMAP core,
segregating application tasks and limiting design flexibility.
The RTXC/mp RTOS presents the two cores that comprise the OMAP5912 as a
single logical processor that lets the developer distribute the
application’s code and kernel objects to the processor most suited to
the needs of the application or for greatest efficiency. And through the
consistent API, application tasks on one core can transparently make
kernel calls that reference and use kernel objects on the other core,
giving the appearance of a single core system.
“This unified approach to multicore design offers significant
programming flexibility while simplifying the overall effort for OMAP
development,” noted Tom Barrett, Quadros CEO. “Two powerful cores with
one operating system API, a common development environment, and an
integrated intercore communications framework add up to considerable
time savings, with improved processor efficiency and reduced design
risk.”
Since developers can use common tools for both cores, system
development time is improved significantly. The configuration tool,
RTXCgen™, included with the RTXC/mp RTOS, gives the developer
high-level control over kernel and application resources. The integrated
compiler and debugger environment of TI’s CodeComposer Studio™ used for
both the RISC and DSP cores offers additional time savings by
simplifying development.
The RTXC/mp operating system has inherent scheduling support for both
asynchronous control and synchronous, constant-rate data flow processes.
Data flow operations, such as those used in DSP, are handled by
lightweight tasks called threads in a cooperative scheduling model,
resulting in very fast performance and context switching. Control
operations are supported by a preemptive scheduler, in a multitasking,
event-driven model. Multiple task/thread priority levels allow the
developer to set scheduling priorities for optimum performance and
processor efficiency.
The RTXC/mp RTOS uses the same application programming interface (API)
as its single core sibling, RTXC/ms, allowing applications to operate
transparently whether in a single- or multi-core environment. In
addition, RTXC/mp supports application designs that employ multiple
cores or multiple processors whether they are heterogeneous or
homogeneous.
Communication between the OMAP cores is handled transparently by the
Poly-Messenger™ intercore communications framework from PolyCore
Software which has been fully integrated with the RTXC/mp RTOS.
Poly-Messenger is a next-generation software infrastructure for embedded
multicore interprocessor communication. It supports both connectionless
message passing and intelligent data transfers.
Availability
RTXC/mp RTOS for OMAP ships Q4 2004. The RTXC/mp SDK is designed for
use with the OMAP5912 Starter Kit (OSK) using TI Code Composer
Studio™. The OSK and Code Composer tools are available from Spectrum
Digital (www.spectrumdigital.com) or from TI’s worldwide distributor
network. For more information about RTXC/mp, visit

About the RTXC Quadros Family of Real-time Operating Systems
RTXC/mp is one of four highly scalable real-time operating systems
in the RTXC Quadros family, offering distinct performance advantages for
each of the major processing models. RTXC/ss (single stack) utilizes a
cooperative scheduler to support high data rate and signal processing
applications. RTXC/ms (multi-stack) is optimized for control processing
using an event-driven, prioritized, preemptive scheduler. RTXC/dm (dual
mode) marries RTXC/ms and RTXC/ss and is ideal for convergent processing
applications which combine DSP/dataflow and RISC/control processing in a
single-core architecture. Both RTXC/ms and RTXC/dm are brought together
under RTXC/mp in various combinations to support multicore and
multiprocessor implementations.
About Quadros, Systems, Inc.
Quadros Systems, Inc. develops and markets RTXC technology, bringing
together RTOS, hardware and software professionals into one development
