World’s First Convergent RTOS from Quadros Systems Supports
Analog Devices’ Blackfin processor
RTXC/dm-a unique Dual-Mode RTOS-delivers a fully optimized
development and run-time environment for ADI's Blackfin™ processor
with its unified single core RISC/DSP architecture
HOUSTON, TX, November 8, 2004 - Quadros Systems, Inc., a leading
supplier of configurable and scaleable real-time operating systems
(RTOS), today announced RTXC/dm, the first RTOS that combines a
traditional task-based kernel architecture for real-time control
processing with a specialized executive for DSP and dataflow
operations using a common API. This unified RTOS solution enables
both types of application code to run fully optimized on a single
processor. The development of this innovative RTOS technology by
Quadros Systems has been driven by a fast growing demand for
support of this new generation of convergent processor architectures.
Gerald McGuire, General Manager of Media Platforms & Services
Group at Analog Devices, welcomed the availability of RTXC/dm for
Blackfin: "This Quadros RTOS with its innovative dual mode technology
is the first operating system designed to take maximum advantage of
the unified control and signal processing capabilities of the
Blackfin processor architecture. The single core convergent
approach for ADI's Blackfin processor offers more flexibility and
simplicity at a lower cost for a wide range of applications-from
traditional industrial control to embedded media applications"
New convergent architectures, such as ADI's Blackfin processor,
are rapidly gaining market share in high-volume consumer multimedia
electronics applications, one of the most rapidly growing segments
in embedded systems development. Such next-generation devices merge
the power and flexibility of a RISC engine and a DSP processor into
a single unified core, thus greatly reducing hardware cost, power
consumption and software complexity.
Previously, to develop applications using these convergent
processors, the developer had to choose between an RTOS optimized
for a real-time control with an event-based processing model, or
one designed to support a dataflow-intensive DSP model. The
dual-mode RTXC/dm from Quadros is the first RTOS to elminate this
problem by enabling optimized real-time execution for both RISC
and DSP code.
A conventional RTOS for a RISC processor provides an optimized
environment for asynchronous, event-driven application tasks
typical of control applications. DSP code, on the other hand,
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. In signal processing and
dataflow processing, a specialized lightweight executive with
minimal context, allows the DSP code to execute with maximum
efficiency.
When DSP application code is executed using a traditional
task-based kernel, processing efficiency and overall data
throughput can be adversely affected. Conversely, if control
system application code runs in an executive designed for DSP
and dataflow processing, the application will likely be
affected by delayed responses to asynchronous events in the
system. Other undesirable effects can include code bloat, poor
latency performance, and extended development schedules.
Low-cost, low-power convergent applications cannot afford
the performance hit of these inefficiencies. It is important
for the application developer to concurrently manage
high-speed dataflow processes and event-driven control
processes, and to do so as efficiently as if each were
running on a dedicated MCU or DSP.
RTXC/dm is the first RTOS to specifically to address this
problem. Its dual-mode architecture has been designed to
deliver optimum performance for users of convergent RISC/DSP
processors. By combining a lightweight executive requiring
minimal context for DSP threads with a protected prioritized,
preemptive kernel for event-driven tasks, RTXC/dm ensures
that both RISC and DSP application code execute with maximum
efficiency.
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.
