An upgrade to IAR Embedded Workbench for Renesas RX adds features that measure a number of execution aspects that provide insight into how well an app performs on the microcontroller (MCU). They also identify opportunities for tuning and optimizing software performance. The performance analyzer can be enabled by IAR J-Link debug probe or Renesas E1/E20 emulators and works in real-time on hardware. It measures the number of executed instructions, execution time and cycles, and number of accepted interrupts and exceptions and cycles spent in them. It is non-intrusive and does not slow down the execution of an application. IAR SYSTEMS SOFTWARE INC., Marlborough, MA. (508) 281-6680.
