Dusseldorf, November 28, 2011 – Renesas Electronics Europe, a premier provider of advanced semiconductor solutions, today announced the availability of embOS from SEGGER on Renesas’ V850E2/Mx4 32-bit microcontroller (MCU) series. The embOS product is a priority-controlled real-time operating system (RTOS), designed to be used as a foundation for the development of embedded real-time applications. It is a zero interrupt latency, high-performance RTOS optimised for minimum memory overhead in both RAM and ROM. It features high speed and versatility, providing the benefits of a fully-featured multitasking system.
As well as being high performance, Renesas’ V850E2/Mx4 series of MCUs offer rich connectivity options, such as Ethernet, USB host, USB function and CAN, making them an ideal platform for the multiple connectivity stacks available from Segger. Renesas’ V850E2/Mx4 series of MCUs are now available with Segger’s embOS/IP and emUSB.
The embOS/IP is a CPU-independent TCP/IP stack, a high-performance library optimised for speed, versatility and memory footprint. The emUSB is a high-speed USB device stack specifically designed for embedded systems, which can be used with embOS or any other supported RTOS.
Renesas’ V850E2/Mx4 series of MCUs comprises both single and dual core devices with high processing performance of 2.56 Dhrystone MIPS per MHz per core, which is 1.4 times higher than the company’s previous V850E2 core. The V850E2 CPU core extends its floating point units (FPUs) to facilitate greater accuracy and range in floating point numbers, making it suitable for applications that require high-speed data processing or complex algorithm calculations. By using the dual core solution, embedded system designers can benefit from the world’s highest processing performance of 1024 DMIPS at a clock speed of 200 megahertz (MHz), while still maintaining low power consumption of 0.88 milliwatts (mW) per Dhrystone MIPS, which is 60 percent less compared to using only one core. In addition, the internal system bus that connects each CPU and DMA controller to the peripheral functions has multiple layers. The bus has a total of three layers: one layer for each CPU, and one layer for the DMA controller. The multilayer internal system bus reduces the overhead due to bus arbitration, achieving high-speed real-time operation.
