Leading RTOS for StarCore Now Available in Dual Mode Version for
Convergent SC2000 Family
Quadros Systems unique RTXC dual mode RTOS optimizes control and
DSP code on latest generation of StarCore synthesizable cores
EW2005: 10-130
Embedded World 2005, Neuremberg, Germany, February 22, 2005 - Quadros
Systems, Inc., a leading supplier of configurable and scaleable real-time
operating systems (RTOS), announced dual mode RTOS support for the latest
StarCore processors. RTXC/dm is the first RTOS to support both multi-stack
and single-stack operation within the same API development and run-time
environment, allowing both RISC and DSP code to run fully optimized on a
single core. The dual-mode RTXC Quadros RTOS addresses the needs of
convergent processor designs, such as the recently launched StarCore
SC2000 family, that are rapidly taking market share of high-volume consumer
multimedia electronics applications, one of the fastest growing market
segments.
These new generation devices provide the power and flexibility that once
required a RISC + DSP design in a single unified core, thus greatly
reducing hardware cost, power consumption and software complexity. The dual
mode RTXC/dm from Quadros Systems is the first RTOS to address the dual
nature of convergent processors by optimizing real-time execution of
applications that use both control and dataflow code.
"RTXC is already a leading choice for StarCore processors," noted Allen
Hyman, Strategic Alliances Manager at StarCore LLC. "With this innovative
dual mode RTXC Quadros RTOS technology, the SC2000’s enhanced performance
and cost benefits can be fully exploited. The single core, convergent
approach delivers greater simplicity and flexibility at lower cost, and
RTXC/dm allows these benefits to be accessed directly by users."
Traditionally, embedded multimedia electronics applications requiring both
RISC and DSP functionality have targeted separate cores with separate
development teams and separate development tool chains. The convergence of
control and dataflow functionality on a single core has many obvious
advantages, both in hardware and software, particularly in high-volume
consumer applications. A unified processor lowers unit cost, simplifies
system complexity, and reduces power consumption-significant advantages in
price-critical applications that are often handheld.
Working within a single software environment for an application—both during
development and at run-time—is also of major benefit. Using a single
development environment can shorten time-to-market as it minimizes the tool
learning curve, inter-team development resolutions and dual environment
debug time. Until now, however, no RTOS has addressed the problem of
optimizing for the very different run-time requirements of RISC and DSP
application code on the same core.
A conventional RTOS for a RISC processor provides an optimized multi-stack
environment for embedded applications that are typically interrupt-driven
and involve frequent changes of program flow. Conversely, DSP code needs to
execute a tight set of repetitive data manipulation functions to completion
within a defined timeframe, and must respond rapidly to changing data sets.
Therefore a lightweight, single-stack environment enables the DSP code to
execute with maximum efficiency.
If DSP threads are run under a multi-stack RTOS designed to support
efficient execution of conventional control flow/interrupt-driven tasks,
the response time to changing data-sets takes a significant hit. Similarly,
RTOS environments designed for dataflow applications do not handle the
multiple interrupts of an interruptive, control-driven application.
In the low-cost, low-power application targeted by convergent processors,
such a performance hit is untenable. Quadros RTXC/dm is the first RTOS that
specifically addresses this problem, delivering optimum performance for
convergent control-dataflow applications. By providing a single-stack
environment for DSP threads, and a protected multi-stack environment for
interrupt-driven tasks, RTXC/dm can ensure that both RISC and DSP
application code execute with maximum efficiency.
Quadros RTXC/dm for the StarCore 2000 family supports StarCore's advanced
architectural features, such as user and supervisor privilege levels, as
well as offering hardware memory protection, ensuring the highest level of
code security and data integrity.
Price & Availability
Single-project licenses for RTXC/dm start at $15,500. Price includes a
source code distribution and a Software Development Kit (SDK).

About the RTXC Quadros Family of Real-time Operating Systems
RTXC/dm 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 lightweight specialized executive 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 (multiprocessing) 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
team to provide innovative technology that maximizes real-time
responsiveness and eases the development process for customers. In
