MENTOR EMBEDDED NUCLEUS RTOS SOLUTIONS Embedded operating systems matter more today Complex microprocessors lie at the heart of every electronic device. Embedded systems today – from mobile phones and industrial controllers, to software-defined radios and medical devices such pace makers and handheld monitors – all demand sophisticated software to get the job done. The role of an embedded operating system (OS) is to provide a software foundation that interfaces to the microprocessor, delivering a set of core services upon which to build and deploy applications. But not all operating systems are created equal. In fact, very few meet the full range of requirements demanded by today's more advanced products. These demands include real time responsiveness, high performance, low-resource usage, and breadth of services. Introducing the Nucleus Real Time OS Nucleus® Real Time OS is central to the Mentor Embedded™ software solution. Nucleus empowers a full range of electronic products, and to date, has been deployed in billions of devices running on hundreds of different types of microprocessors. Why Nucleus is the smart choice Not only is Nucleus a proven, highly efficient, and reliable OS, but it offers a comprehensive set of system services that scale to any target hardware. These characteristics combine to deliver best-in-class performance while reducing resource usage, enabling developers and device manufacturers alike to bring a more profitable product to market. Nucleus is a proven, highly efficient OS with a comprehensive set of system services.
