Popular DSPs gain real-time support

OSE Systems has developed a support package for the Texas Instruments TMS320C64x digital signal processor architecture.

OSE Systems has developed a support package for the Texas Instruments TMS320C64x digital signal processor architecture.

The OSE robust fault-tolerant real-time kernel offers the system designer the highest level of abstraction and portability at the applications level while implementing systems with optimised low-latency drivers for high-bandwidth I/O.

Designers can now create and deploy real-time DSP and multiprocessor applications with minimum overhead while managing the complexities of interprocessor communications.

"Over the past ten years OSE has demonstrated technology leadership in the wireless communications market", said Will Strauss, president of Forward Concepts.

"Understanding the fault-tolerant attributes of base stations infrastructure and switching centres, compounded by the complex dynamics of a rapidly evolving communications market, puts OSE in a unique position for success", he concluded.

"The combination of TI's C64x DSPs and OSE's operating system is a perfect match for the high-performance multiprocessing environment found in the wireless infrastructure market", said Jerold Givens, worldwide marketing manager for TI's wireless infrastructure business unit.

"OSE's expertise in real-time software components for telecommunications and data communications will give our customers differentiated solutions and capabilities".

OSE provides fast, deterministic real-time performance, combined with reliability, scalability, portability and a small footprint.

The minimum C64x configuration of the kernel requires less than 8Kbyte of memory.

In a hard real-time environment, system behavior must remain strictly deterministic.

Interrupt routines in the kernel are extremely efficient, resulting in very low interrupt latency.

A novel feature of OSE allows interrupt processes to be scheduled in response to a software event as well as a hardware interrupt.

The direct message passing design of OSE is the most powerful and safe method of interprocessor communications.

OSE can be used between two processes located on the same CPU or two processes in remote CPUs.

Because OSE messages are sent directly from one process to another, ownership of a message is never shared and the operation is fully transparent between different CPUs.

This capability is independent of the underlying hardware topology and is provided without compromising key design parameters.

OSE for Texas Instruments TMS320C64x DSPs is available immediately.
