Nullstone supports ACE Associated Compiler Experts' DSP-C language extensions in its Automated Compiler Performance Analysis Tool

ACE Press Release

San Jose, California, USA 10 April, 2000

Customer demand creates strength for DSP-C standard

ACE Associated Compiler Experts announced that Nullstone Corporation (Pleasanton, Calif., www.nullstone.com) is now supporting ACE's DSP-C language extensions in the latest release of their compiler performance analysis product. Nullstone's new release will be available later this month. ACE's DSP-C is provided standard with the DSP release of its CoSy® compiler development system.

Nullstone's Automated Compiler Performance Analysis Tool uses a QA approach of test coverage and isolation to measure the quality and performance of an optimizer. The NULLSTONE methodology increases compiler performance by isolating performance regressions and defects; identifying opportunities for improvements; establishing development completion criteria; and providing detailed competitive data.

Nullstone's analysis product for compilers developed with the C language consists of over 6,500 individual tests covering more than 40 compiler optimizations. It automatically tests the compiler optimizer and generates reports that clearly identify failures. It supports both native and embedded development environments as well as architecture-independent operation for cross-architecture comparisons.

"We are customer driven, and we see the potential future in the DSP-C standard," said Christopher Glaeser, president of Nullstone. The DSP-C specifications are supported in the successful DSP release of the CoSy compiler development system of ACE, and we see the continued support of the extensions by other companies. A number of our customers are eager to get their hands on it."

The C programming language is increasingly used to program DSPs. The DSP-C language extensions are particularly suited to compiler development for DSPs, offering fixed-point and saturation arithmetic, circular buffers, and memory spaces, unavailable with the standard C programming language. ACE has submitted a set of extensions, which have been developed in collaboration with the DSP industry, to the relevant working group of the ISO/IEC Joint Technical Committee for inclusion in the next official release of the ISO/ANSI C programming language.

"Performance is crucial in DSP compilers, and we are pleased that DSP compiler developers can now evaluate their compilers with the Nullstone suite to analyze the performance," said Rob Kurver, ACE's managing director. "The CoSy compiler development system, combined with the Nullstone tools, help compiler developers to create the most powerful compilers with the shortest time to market. ACE is committed to providing the most comprehensive, robust compiler development platform in the industry."

ACE Associated Compiler Experts bv (a wholly owned subsidiary of ACE Associated Computer Experts, Amsterdam, The Netherlands) is a world leader in the production of compiler development tools. Its open CoSy compiler development system gives compiler developers the ability to achieve a similar leading edge position in the construction of better and faster optimizing compilers for architectures ranging from 4-bit DSPs to 256-bit VLIW processors. CoSy also accommodates a wide range of programming languages including C, DSP-C, C++, Fortran and Java.
