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 powerful messaging service, LINX (with its Open-Source protocol) allows for transparent Inter Process Communication (IPC) in a heterogeneous Operating System environment for multicore applications, regardless if they run on a single CPU, several cores, or different nodes in a distributed system. LINX makes complex applications easier to partition and distribute. LINX also makes the resulting code easier to scale and maintain, enabling system developers to expand their systems, perform upgrades, and take advantage of the latest 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.

Enea’s DSPNet, a compact, high-performance secure IPv4v6 stack optimized for OSEck and DSP applications help system developers lower network processing costs while taking full advantage of the DSP’s real-time processing capabilities.
