It may only be 2.5% on average, but the Tasking C166/ST10 Toolset Version 8 C/C++/EC++ compiler cranks out tighter code using Data Flow Analysis Peephole (DFAP) optimization for improved execution speed and code compaction. The compiler supports the Standard Template Library (STLport). The toolset also includes the Embedded Development Environment (EDE) that now incorporates flash-memory programming utility. The EDE now generates startup code based on customization control-panel inputs. Prices start at $2650.
