Overview
Description
In development of embedded systems, C/C++ Compilers for the RX Family offer powerful optimizations for enhancing execution speed and code efficiency, and the utilities to increase productivity. Products differ depending on each integrated development environment.
Features
- ANSI-compliant
- Support C89, C99(Except for variable length array), C++ of ANSI
- Superior optimization
- Optimization produces code that has excellent performance in execution.
- Optimization for size has also been strengthened to produce more compact code.
- A variety of optimization options is specifiable through the GUI of the IDE you are using.
- In addition to optimization for compilers and standard libraries, optimization at the linker level is included.
- Cooperated with RX MCU architecture
- Supports a high-speed interrupt function (
-fint_register
option) - Provides intrinsic functions
- Supports a high-speed interrupt function (
- Support for easy translation from existing MCUs [ Learn more ]
- Supports the utilization of software resources for existing M16C and H8S and so on
- Supports the translation to more compact object for RX smoothly by the compiler options absorbing/reporting compiler-specific language and powerful optimizations
- Highly accurate simulator
- Possible to evaluate and debug with high accuracy by a variety of debugging functions such as an array of break functions and virtual interrupt function
- An MISRA C rule checker supports the description of high-quality program [Professional edition only]
- Supports automatic checking of C source code based on the MISRA-C: 2004/2012 rules as compiler options
