Optimized C/C++ code generation

toolchains

The Renesas compiler toolchains

(compiler, assembler and linker)

support the full C++ language

specification and are backward

compatible with C. They have

extensions for complete embedded

system control directly from C,

without requiring the use of any

assembler code. These extensions

cover:

• Interrupt service routines

• Condition control register

operations

• Sleep instruction

• Pseudo functions for instructions

such as multiply-and-accumulate

and decimal add and subtract

• Control of the optimized

addressing and function call

features of the device

architecture and instruction set

The inter-module optimizing linker

produces optimized software load

modules by performing global

optimizations on your application.

Free evaluation HEW download

The flexible licensing technology

in Renesas’ compiler toolchains

means you can download a free

evaluation copy of HEW with the

compiler and generate unlimited

code for 60 days. This is very

useful for benchmarking optimiza-

tion efficiency and architecture

performance. After 60 days, code

size is limited to 64 Kbytes, which

still allows you to evaluate the

architecture or experiment with

peripherals. For smaller devices,

you can even complete a full

application, since the evaluation

version is identical to the full

version with the exception of the

code-size limits, including all

optimization options.
