As an established real time operating system shipped in over three billion devices powered by hundreds of different types of MPUs and MCUs, it is unsurprising that Mentor Graphics’ Nucleus embedded RTOS is ready to fall lockstep into the Internet of Things. New SoC architectures designed for IoT require operating systems such as Nucleus optimized for size and performance. What’s unique – and maybe a pleasant surprise even to Mentor – is that developers in the nascent wearables market have already begun to design their RTOS into medical, fitness, and security wearable devices.
“We may be new to wearables,” said Warren Kurisu, Director of Product Management for Mentor’s Runtime Solutions, “but multicore is working its way into that market and Nucleus’s built-in power management framework, out-of-the-box connectivity, and scalability make it a perfect fit, allowing designers to address a broad spectrum of wearable devices for faster time to market. Nucleus is more than just a kernel; it is a complete stack and file system,” said Kurisu.
导师嵌入式Nucelus RTO为云连接提供了广泛的协议支持，包括低功率IoT，M2M，安全性，防火墙和基于IP的网格和零配置网络。带有过程间通信（IPC）和远程过程生命周期的集成多项框架支持启动并根据用例关闭单个处理器/内核，以节省功率。
内置电源管理框架支持处理器中的低功率功能，包括动态电压频率缩放（DVF），低功率和睡眠模式以及CPU空闲模式。该框架通过使用简单的高级API来管理每个外围设备，一组外围设备或整个可穿戴系统的功率状态。当更改电源状态时，电源管理框架可以协调对处理器模式，操作频率和外围设备操作的协调控制。
该操作系统可在高性能MPU和资源受限的MCU中提供内存空间分区，以支持软件更新和升级，设备配置以及从用户应用程序商店下载的软件下载。它包括丰富的IPv4/V6网络堆栈，M2M协议以及IoT应用程序的安全性和云连接性。
