Enea Embedded Technology Unveils OSE 5.0 Real-Time Operating System

3/31/2004 - Enea Embedded Technology announced version 5.0 of the OSE real-time operating system (RTOS). Optimized for wireless devices and telecom networking systems, OSE 5.0 features dynamic program management for persistent media, new virtual memory and memory savings capabilities, enhanced networking support, multimedia flash support, and new ease-of-use features that make it easier than ever to install and configure. OSE 5.0 will initially be available for ARM and Xscale processors, including Motorola’s new ARM-based i.MX21 platform, which is optimized for mobile wireless applications. PowerPC and MIPS support will follow in Q4 this year.

“Version 5.0 marks a significant upgrade for the industry’s most advanced high-availability RTOS,” said Eva Skoglund, product marketing manager at Enea Embedded Technology. “OSE 5.0 is easier than ever to configure and start up, and provides a host of new memory/program management and networking capabilities that enhance efficiency and flexibility, boost performance, and simplify overall system design and integration.”

Networking support for OSE 5.0 includes a dual-mode IPv4/IPv6 TCP/IP stack with MobileIP capability. The stack is available in two versions, a full-featured stack for routing applications that provides advanced security, virtual routing, and NAT capabilities; and a compact, high-performance stack optimized for deeply-embedded, resource-constrained applications. OSE 5.0 also offers a comprehensive suite of networking applications, including DHCP, DNS, FTP, TFTP, Telnet, Web Server, SSL and IPSec.

OSE 5.0 features dynamic program management for persistent media such as flash memory, which enables programs to be loaded into flash, execute in place, and survive restarts. OSE 5.0 provides full memory protection for dynamically loaded programs, reclaims memory without fragmentation when it unloads programs, and supports loading/unloading of drivers when new hardware is added/removed. OSE 5.0 also provides multimedia flash support for real-time multithreaded applications such as streaming video.

OSE 5.0 provides enhanced virtual memory support that enables it to leverage both the memory protection and virtual memory translation facilities of hardware MMUs. OSE 5.0 also provides new memory savings features, including a modular architecture that reduces static memory usage, and a dynamic software download mechanism that minimizes buffer usage.

OSE 5.0 provides a number of new features that make it easier to configure, start up, and use. Each board that OSE supports, for example, comes with a Software Reference System that provides turnkey build facilities. This system, which includes a build and configuration framework, board-specific drivers, a full-featured OSE sample system, and sample application modules, enables designers to bring up a full system in less than an hour without a debugger. OSE also supports dynamic OS and system configuration, which enables systems to determine their configuration during run time instead of compile time, and enables the configuration to be changed and the image updated while the system is running. To enhance reliability and portability, OSE 5.0 provides separate application and system programming interfaces.

More on the OSE RTOS
OSE is a compact, pre-emptive, memory-protected, multi-processor RTOS optimized for distributed, fault-tolerant applications that demand the utmost in reliability, security, and availability. OSE enhances reliability and availability by utilizing the target processor’s memory management unit to build a firewall between kernel and application processes, thereby preventing these processes from corrupting each other. OSE further enhances reliability and availability by providing automatic failure detection and supervision (health monitoring) of system processes and applications.

To streamline and simplify distributed communications, OSE’s Link Handler provides an application- and device-independent message-passing protocol that makes interprocess communications transparent to programs running on different CPUs. OSE also features a power management system that extends battery life, a crash-safe file system with flash support, and dynamic download capability, which enhances mobile device flexibility by enabling new applications to be downloaded to systems as they operate in the field.

Development support for OSE includes the ARM compiler (ARM Developer Suite) and C source-code debuggers from ISYSTEM (winIDEA) and Mentor Graphics (X-RAY). To facilitate higher-level application debugging, OSE also offers OSE Illuminator. Tightly integrated with both ISYSTEM and X-RAY, Illuminator enables programmers to monitor and control their applications as a sequence of events, such as context switches and message passing between processes. OSE also offers its own Softkernel simulator, which enables designers to start developing their OSE/ARM applications in advance of hardware availability. Board Support Packages are available for Motorola’s iMX21, Intrinsyc’s Cerfboard and CerfPOD, Vytek’s RedHawk, and ARM Ltd.’s Integrator.

OSE 5.0 is available as of June 2004 from Enea. Pricing information can be obtained via the local Enea sales offices.
