The Renesas H8 C/C++ Compiler is an optimising ANSI C and ANSI C++ compiler for H8, H8S, H8SX family microcontrollers. The package includes a compiler, assembler, linker. A variety of optimisation features allow you to generate highly optimised PROMable code. In particular, code can be optimised for size or speed to match the requirements of the particular application being developed. The compiler toolchain is supplied as part of the High-performance Embedded Workshop IDE.

HEW, a powerful yet easy to use tool suite, features an industry standard user interface and is designed using a modular approach seamlessly incorporating device family-specific C/C++ compilers and the debugger elements for various debugging platforms including emulators and evaluation boards.
