Optimizing Compilers

The Green Hills Optimizing Compilers for ST100 utilizes Green Hills' global optimizer with architecture-specific optimizations. The compiler has user-selectable options to generate fast, full-featured GP32 code, or compact, efficient GP16 code. The Green Hills ST100 Optimizing Compilers support the following ST100-specific features:

CodeBalance - The ST100 compilers are fully integrated with Green Hills CodeBalance technology. Given a set of user-supplied constraints, CodeBalance uses profiling information to reconfigure the compiler on a function-by-function basis to use the optimal mix of GP16 and GP32 modes.

Small Data Area (SDA) and Tiny Data Area (TDA) Optimization - The ST100 compilers can collect frequently accessed data into special blocks of memory that can be accessed more efficiently than regular memory.

Hardware Loop Support - The ST100 compilers take advantage of the ST100's hardware loop capabilities.

Hand-Coded Library Functions - Many of the most commonly used functions have been hand-coded in ST100 assembly for maximum performance. These routines include: memset, bcmp, and other string-manipulation routines; and many 64-bit integer math routines.

Intrinsic Functions - The ST100 compiler provides an extensive list of intrinsic functions, giving advanced C and C++ programmers easy, highly-optimized access to the most powerful ST100 instructions, including DSP capabilities.

40-bit Arithmetic Support - The ST100 compilers take full advantage of the ST100's native 40-bit arithmetic capabilities.

Predication Support - The ST100 compilers utilize the ST100's predication model, which is effective at removing branches and decreasing penalties from branch mispredictions.
