Microcontroller development environment increases performance and lowers power

Use in diverse applications such as motors in home appliances or industrial equipment has resulted in demand for increased processing speed in the microcontrollers used. Longer operating times are required in battery-operated equipment such as healthcare equipment and fire detectors, increasing demands for reduced power consumption in the microcontrollers.

The compiler takes advantage of the low-power capabilities of the RL78 family and can be used in combination with the e² studio (eclipse embedded studio) integrated development environment (IDE).

Key features of the compiler are improved microcontroller processing performance through optimisation technology. The performance of programs coded in standard ANSI C is significantly improved, claims the company, compared to the existing Renesas compilers, without any changes to the code itself. The interrupt response performance, which is critical at the system level, is improved by up to six times.

Additionally, the compiler includes porting support functions for porting from earlier compilers. This allows the users to make effective use of existing software assets.

It contributes to reduced power consumption in user systems by reducing the time spent in the normal state is reduced, and increasing the time spent in the standby state. It also generates code that is 10% smaller than that generated by earlier Renesas C compilers. This allows even more functions to be included in systems.

Functions for checking items in the MISRA-C:2004 guidelines are performed automatically at compile time, preventing missed checks and incorrect file specifications.
