ACE’s latest CoSy compiler development system optimizes for extreme architectures

Amsterdam – 14 May 2013 – ACE Associated Compiler Experts bv, world leader in tools and services for professional compiler development, announces the availability of the 2013 Spring Edition of its CoSy compiler development system. Integral support for complex architecture features allows compiler developers now to build, optimize and tune compilers for compute-intensive application domains and extreme architectures.

Standard architectures and their software tools are not adequate to reach the required performance and power levels for application specific domains like audio, video and for new domains like next generation communication standards and embedded vision. Instead, dedicated architectures or extensions to existing architectures are developed together with target specific applications code, using a standard compiler that leaves the tuning up to the application developer. In this 2013 Spring edition, extended and new features like the Target Interface Mechanism and Code Generator Feedback provide for an integral system to create compilers that reach the best possible tradeoffs in performance and application portability for existing and emerging application specific processors.

Using the new Target Interface Mechanism in CoSy, compiler developers can now steer the compiler optimizations to take full advantage of architecture specific features, while abstracting these from existing and validated compiler algorithms.

One of CoSy’s unique compiler features, its modular design and flexibility, has allowed the support for feedback mechanisms in a compiler to steer the compilation for optimal results. The Code Generator Feedback feature in this 2013 Spring Edition provides information from the architecture specific Code Generator to do better decision making in high level optimizations and transformations, resulting in better optimization strategies.

CoSy’s flexible and adaptive type description enables the support for unconventional data types, which are typical for application specific architectures, with parameterizable data size, alignment, etc. in a consistent way and with C level programming support for application developers.

Further tuning of compilers can be reached using 100+ compiler engine options, the 20+ new compiler engines and 100+ improvements from customer and partner feedback. All new components and improvements are robust and in product shape as a result of the thorough testing and validation infrastructure used.

The 2013 Spring Edition comes with a revised, extended and improved set of documentation for the professional compiler developer. Together with the training materials and the ACE compiler experts’ first line support program, compiler developers can go to the finest level of detail in their compiler endeavor.

Overall performance for 100+ industry-standard benchmarks show a 15% out of the box improvement for commodity architectures since the last major CoSy release. Billions of devices have already been shipped containing CoSy supported application specific processors, which typically have factors better performance/power profiles than regular processors.

The CoSy Spring 2013 Edition is readily available

What is “real-time control” and why do you need it?

Sponsored by Texas Instruments

Real-time control is the ability of a closed-loop system to gather data, process that data and update the system within a defined time window. If the system misses that defined window, its stability, precision and efficiency will degrade. Diminished control can be detrimental to system performance; for example, not achieving the necessary speeds or even overheating. This article will explain the functional blocks of a real-time control system and provide an example of a robotics application.

Seamless Ethernet to the Edge with 10BASE-T1L Technology

Sponsored by Mouser Electronics and Analog Devices

In order to keep up with the breakneck speed of today’s innovation in Industry 4.0, we need an efficient way to connect a wide variety of edge nodes to the cloud without breaks in our communication networks, and with shorter latency, lower power, and longer reach. In this episode of Chalk Talk, Amelia Dalton chats with Fiona Treacy from Analog Devices about the benefits of seamless ethernet and how seamless ethernet’s twisted single pair design, long reach and power and data over one cable can solve your industrial connectivity woes.
