Express Logic’s ThreadX RTOS Extends ARMv8-A 64-Bit Support to Include SMP

San Diego, CA --- Express Logic’s ThreadX RTOS now provides Symmetric Multiprocessing (SMP) support on the ARMv8-A 64-bit processor family, including the ARM Cortex®-A53, Cortex-A57 and Cortex-A72 processors. ThreadX SMP is based on Express Logic’s industry-leading ThreadX RTOS, a small, highly efficient embedded OS that minimizes system overhead and provides lightning-fast, real-time response. With a memory footprint less than 10KB and submicrosecond interrupt responses and context switches, ThreadX SMP complements the multicore architecture of the 64-bit ARMv8-A architecture with the ease of SMP, while retaining hard real-time responsiveness.

ThreadX/SMP offers developers of ARMv8-A 64-bit based products the following:
• Incremental processing resources
• Automatic load-balancing across all cores
• Ease of application programming
• Use of common code for single and multicore versions
• Increased performance without increased programming complexity

With ThreadX/SMP, an application can exploit the resources of multiple processors to serve its threads, without developers having to tailor the program logic to manage and arbitrate among the processors. In a single-processor system, the moment a top-priority thread begins execution, other threads must wait.

With ThreadX/SMP, threads of equal priority can run in parallel on the other processors, effectively balancing overload situations where one processor could not handle the volume of data to be processed. Using ThreadX SMP, the application can launch a second, third or fourth thread, as needed, to help with the processing. The additional threads can be defined at initialization and automatically run on any available processor or created dynamically as the executing thread identifies processing demand beyond its capabilities.
