Compact Kernel for Real-Time DSP Embedded Systems
Enea OSEck, a DSP-optimized version of Enea’s full-featured OSE RTOS, is a full featured, compact, real-time operating system optimized to suit the specific requirements of high performance, memory constrained applications. Built on a compact kernel that has an extremely small memory footprint, Enea OSEck still combines rich functionality with high performance and true real-time behavior for single and multicore devices.
On top of an extensive list of supported processors and advanced, portable, board support packages (BSPs), Enea OSEck provides efficient interprocess communications (IPC) services, networking protocols and security features that enable DSP developers to design distributed systems using Enea OSE’s built in message passing architecture together with Enea LINX and the newest generation Internet protocols and security standards provided by the OSEck DSPNet solution.
- Small and efficient
- Built for distributed heterogeneous environments
- Highly portable; optimized for single- and multi-core DSPs

OSEck (OSE Compact Kernel) is a DSP-optimized version of Enea’s full-featured OSE RTOS. Occupying as little as 8 kbytes of memory, OSEck delivers fully-preemptive, event-driven, real-time response and features built-in error detection and handling. This combination makes OSEck ideal for wireless, automotive, industrial control, medical and mil/aero applications with tight memory constraints that require reliable real-time control and signal processing.
Like all members of the OSE family, OSEck employs a high-level message passing programming model that makes it easy to break complex applications into simpler concurrent processes, each communicating via high-speed direct messages. This high level of abstraction makes complex applications easier to conceptualize, model, partition, and debug. It also provides transparency that separates applications from the details of the underlying hardware and physical topology, thereby making the resulting code more scalable and easier to migrate.
OSEck provides a simple yet powerful API that offers a high level of abstraction, typically enabling programmers to code the bulk of their application with just eight system calls. This versatile API, together with OSEck’s high-level messaging protocol, reduces application size and complexity, and makes programs easier to maintain, read and understand. OSEck provides a subset of the full-featured OSE API, making it easy to migrate applications between OSEck, OSE, and OSE Epsilon with few if any changes to the application code.
Enea’s LINX interprocess communications (IPC) services extend the benefits of message passing to OSEck applications distributed across multiple DSP cores. LINX makes complex applications easier to partition and distribute. LINX also makes the resulting code easier to scale and maintain, enabling equipment makers to expand their systems, perform upgrades and take advantage of the latest DSP hardware with minimal impact on existing applications.

LINX IPC services also simplify the design of distributed systems that combine CPU cores running OSE and DSP cores running OSEck, either on the same or multiple processors. Many distributed systems utilize general-purpose CPUs for the control plane and DSP cores for the user data plane. Through LINX, OSE and OSEck provide a unified solution that enables designers to leverage the control, networking, and application processing facilities of OSE on the host processor while utilizing the hard real-time attributes of OSEck on the DSP core, without having to learn multiple programming environments.
The OSEck Shell provides easy run-time access to information through built-in or user defined commands and a generic connection (such as Telnet, SSH, or LINX).
Enea’s OSEck Soft Kernel simulation environment allows OSEck processes to run on a Windows, Unix, or Solaris host. It can also work together with a running real-time system. This enables designers to build hybrid soft/hard OSEck target environments in which designers can run a portion of their application on the host and migrate it to hard targets as hardware becomes available.
