Enea Delivers DSP Support; Ports OS to ARM Processors
Real-time operating system (RTOS) manufacturer Enea OSE Systems has announced the availability of the OSE RTOS kernel for digital signal processor (DSP) designs. Through this new release, Enea has now made its RTOS compatible with DSPs from Texas Instruments (TI) and Lucent. In addition, the RTOS will support new DSP platforms within a few months.
In addition to providing DSP support, Enea announced it is incorporating support for distributed processing into the OSE RTOS with the addition of OSE Link Handler.
In a today's base station designs, DSPs are being used to process encoded and decoded signals while other central processing units control the rest of the system. Therefore, managing the communication between these two sets of processors is essential to proper system design and operation.
OSE Link Handler has been released to improve the interconnection and communication between these processing units. With this feature, engineers can build dynamic multi-DSP and multi-network systems without any need for static or global declarations. In addition, engineers can also develop multi-processor networks that transparently communicate with each other.
To provide transparent communication, Enea's Link Handler and RTOS implement a message-passing mechanism that involves kernel calls without sharing memory or message ownership. This means that it is typically not possible for processes to overwrite each other's memory spaces even when sharing data.
In addition to providing the Link Handler functionality, Enea has developed the Illuminator debugging environment for its RTOS. This environment provides a graphical user interface (GUI) with information on variables, execution path, and memory usage.
Increased Processor Support
Enea also announced that its OSE RTOS is being ported to the ARM7 and ARM9 processor families. Enea offers full debugging capabilities for systems using the ARM7 and ARM 9 processors. In addition, Enea delivers Internet protocols, such as a small TCP/IP stack for these processors.
OSE for the ARM7 and ARM9 families is available immediately. Pricing starts at $8,000 for a development license.
