OSE Epsilon is a fast, small, low-cost RTOS optimized for resource constrained embedded microcontroller applications. This fully pre-emptive real-time kernel, written entirely in assembler, is optimized for each target processor, employs efficient system calls to reduce application code size, and occupies just 4 kbytes of memory.
.
OSE Epsilon incorporates built-in error handling to enhance end-product robustness and reliability. OSE Epsilon is also available with a crash-safe flash file system and a suite of basic networking protocols, including TCP, UDP, IP, ICMP, ARP, Proxy-ARP, RARP, PPP, Web Server, DNS client and DHCP client.
OSE Epsilon speeds application development by combining simple yet powerful system calls with high-performance inter process communications services. In fact, with just eight simple system calls, most designers will have all they need to write the bulk of their application.
Like all OSE family members, OSE Epsilon employs a simple, intuitive message passing programming model that makes it easy to break complex applications into simpler concurrent processes, each communicating via a high-speed, transparent, direct message passing protocol.
Enea’s OSE Soft Kernel simulation environment allows OSE Epsilon real-time kernel processes to run on a Windows, Unix, or Solaris host. This capability speeds development by enabling programmers to develop and test their applications on the host before moving them to the target hardware.
