IAR Systems® introduces version 1.20 of the high-performing development toolsuite IAR Embedded Workbench® for RL78. The new version brings highly efficient speed optimizations. IAR Embedded Workbench is a full set of development tools for building and debugging embedded applications. It includes a project manager, editor, compiler, assembler, linker, debugger, and library tools in a user-friendly integrated development environment. Thanks to the longstanding and solid relationship between IAR Systems and Renesas Electronics, IAR Embedded Workbench for RL78 was the first set of development tools to be made available for the RL78 family. From start, the compiler has created very compact code, for example by using intelligent linking and making full use of the hardware multiplier/divider for faster arithmetic. This makes the execution run faster and allows the microcontroller to enter one of its low-power modes after fewer clock cycles. Because the RL78 family is specifically designed for use in low-power applications, the power-saving contribution from having highly optimized code is extremely valuable. Version 1.20 of IAR Embedded Workbench for RL78 brings even more improved optimizations. The code generated for integer arithmetic and floating-point operations is now several times faster compared to the previous version.
