3.8 Compiler intrinsics for Digital Signal Processing (DSP)
The compiler provides intrinsics that assist in the implementation of DSP algorithms.
These intrinsics introduce the appropriate target
instructions for:
- ARM, on architectures from ARMv5TE onwards.
- Thumb, on architectures with Thumb-2 technology.
Not every instruction has its own intrinsic. The compiler
can combine several intrinsics, or combinations of intrinsics and
C operators to generate more powerful instructions. For example, the
ARMv5TE
QDADD instruction is generated
by a combination of __qadd and __qdbl.| Non-Confidential | PDF version | ARM DUI0375H |
