RTOS runs on Blackfin processors
The ThreadX real-time operating system is now available for Analog Devices' new network-enabled Blackfin processors
The ThreadX real-time operating system (RTOS) is now available for Analog Devices' new network-enabled Blackfin processors. The newly available ADSP-BF534, ADSP-BF536 and ADSP-BF537 processors are highly integrated system-on-chip (SoC) solutions for next-generation connected applications such as IP set-top boxes, portable and networked media players, automotive safety, driver assistance and audio and security.

Express Logic's ThreadX RTOS provides Blackfin developers with a technically advanced real-time, multitasking solution.
Express Logic's picokernel architecture results in very high-performance and extremely small memory footprint - less than 4Kbyte for minimal usage - by structuring all system services into separate files with no interdependencies.
Applications only link in routines actually used, thereby eliminating the inclusion of unused services commonly carried by monolithic kernel designs.
ThreadX also includes extremely fast software timers, priority inheritance and pre-emption threshhold, a mechanism to help reduce context switching.
'We're pleased that Express Logic's popular ThreadX RTOS will be available to our new Blackfin ADSP-BF534/536/537 customers', stated Gerald McGuire, General Manager, Media Platforms and Services Group, Analog Devices.

'Express Logic has been a strong partner, and together we have many customers that benefit from using ThreadX on Blackfin processor designs'.
As the first RTOS company to port to the Blackfin platform, Express Logic has developed in-depth technical knowledge of the Blackfin architecture, which has made ThreadX a very popular royalty free solution for Blackfin system developers.
Available across the ADI SHARC DSP and Blackfin processor families, ThreadX is fully integrated with Analog Devices' VisualDSP++ IDE and offers ThreadX kernel awareness for the ADI VisualDSP++ debugger.
The ADI VisualDSP++ debugger integration offers Blackfin developers full RTOS support by detailing all ThreadX resources.
Each application thread may be viewed in a separate window, showing the threads current state and location in the application.
As developers can examine all resources - threads, semaphores, queues, timers, event flag groups, memory block pools and memory byte pools - they enjoy greatly enhanced productivity and are able to eliminate cumbersome searches for resource information in the source code.
Developers can display the status of all ThreadX resources using windows.
'We pride ourselves in our knowledge of the Blackfin architecture, and have moved quickly to port our popular ThreadX RTOS to these new network-enabled processors', said William E Lamie, Express Logic's President.
'One of the main reasons for the tremendous popularity of ThreadX for ADI technology is the outstanding integration with development tools like ADI's VisualDSP++ IDE'.
'The VisualDSP++ debugger integration for ThreadX ensures ADI developers get higher quality products to market in less time'.
ThreadX is available immediately from Express Logic for the new Blackfin processors, and is licensed on a source code, royalty-free basis.
Single product licences start at $12,500, including full source code.
