ARM DEVELOPMENT TOOLSET FOR HANDSET BUILDERS

ARM has assembled a tool bundle in its RealView series; it tailored these tools for the needs of engineers creating mobile applications and services. RealView Development Suite 3.1 Professional tools provide a modelling environment for early software builds for mobile/media products and comprise the RealView Development Suite, the RealView Profiler tool, the ultra-fast Real-Time System Models, and the NEON vectorising compiler. You can use them for applications that will employ the Symbian OS. ARM has integrated the tool suite with its ESL tools to provide a unified tool chain from architectural exploration through to the deployment of hardware and virtual platforms. The models support early software design before silicon is available.

ARM has included a real-time system model of the Cortex-A8 processor that incorporates the NEON advanced SIMD unit. The performance of this model is equivalent to silicon running at 200 MHz or more on a typical host PC, which makes it capable of supporting mobile-application development ahead of silicon availability. Together with the cycle timings that the RealView Profiler—which carries out non-intrusive code analysis and provides code-coverage data—delivers, software developers can obtain a thorough understanding of performance bottlenecks to optimise the applications in advance of hardware. The NEON vectorising compiler enables software developers to take advantage of the NEON advanced SIMD media-processing extensions that use standard ISO C and standard ISO C code to improve, ARM says, performance of individual kernels by up to 400% and complete media applications by more than 200%. The toolset supports cores that include the ARM926EJ-STM, ARM1136JF-STM, and ARM1176JZF-STM. The tool suite is available now.
