ORBexpress Improves Performance Using INTEGRITY 10 on Embedded Multi-core Processors

By Rajani Baburajan, TMCnet Contributor


Objective Interface Systems (OIS), a provider of high-performance, real-time and embedded multi-core communications middleware solutions, announced that its ORBexpress product doubles message throughput when used in conjunction with INTEGRITY 10 on a dual-core processor.


INTEGRITY 10 is a real-time operating system (RTOS) with symmetric multiprocessing (SMP) from Green Hills Software. It provides complete SMP support that is optimized for embedded and real-time use. With SMP support, developers can realize the performance potential of multicore architectures while maximizing software reuse.

"The same architecture that makes INTEGRITY the leader in safety and security in real-time operating systems enables INTEGRITY to scale for embedded multi-core processors," said David Kleidermacher, chief technology officer, Green Hills Software, in a statement.

ORBexpress provides a high-performance communications framework for INTEGRITY 10, enabling real-time and embedded systems to communicate seamlessly with ultra-low latency, company officials said. Featuring a multi-threaded architecture, ORBexpress fully supports SMP for inter-process and intra-process communications. This enables ORBexpress to scale seamlessly in a multicore environment.

"INTEGRITY 10 combined with ORBexpress offers embedded developers an easy path to migrate their mission-critical systems to multicore architectures while maintaining their investment in their high quality code," Kleidermacher added.

Company officials claim that with ORBexpress, SMP support is automatic and requires no additional programming effort from application engineers.

"Our tests showed that operation invocation throughput doubled when moving from a single-core to a dual-core PowerPC at the same clock speed," said Kevin Buesing, director of Technology Services from Objective Interface Systems, in a statement. "This performance gain was achieved using INTEGRITY 10 without modifying the test application code or recompiling the test image."

Recently Objective Interface Systems announced that Communications Research (News - Alert) Centre Canada (CRC) ported a complete APCO P25 waveform and Software Communications Architecture (SCA) radio system to a small form factor Android (News - Alert) device in just one day with zero source code modifications using the ORBexpress communications software.
