Express Logic’s X-Ware IoT platform supports AndesCore RISC-V processors

Royalty-free, RTOS specialist, Express Logic, has announced that its industrial-grade X-Ware IoT Platform, powered by the ThreadX RTOS, provides turnkey support for the AndesCore 32-bit N25 and 64-bit NX25 RISC-V processors.

RISC-V, a standard open architecture instruction set architecture (ISA) is highly portable and enables the open source community to test and improve cores faster than with closed ISAs, explains Express Logic. The RISC-V intellectual property (IP) core is not encrypted, allowing the RISC-V to be used to ensure trust and certifications not possible with closed architectures.

The X-Ware IoT platform is a deeply embedded run-time offering, and includes the ThreadX RTOS, the FileX embedded FAT file system, the embedded GUIX UI framework, the NetX/NetX Duo embedded TCP/IP protocol stack, and the USBX embedded USB support.

AndesCore N25 and NX25 families are 32- and 64-bit V5 embedded cores from the AndeStar V3 family. They are fully compliant with RISC-V technology and provide differential, advanced features, such as Andes Performance Extension to speed up program sequence for memory accesses, branches and other common scenarios, Andes Custom Extension (ACE) to enable user-defined instructions for Domain-Specific Acceleration (DSA), CoDense for code size compression, StackSafe stack overflow/underflow detection to ensure program reliability, and PowerBrake frequency scaling for power saving.

The X-Ware IoT platform contains no open source and has an “extremely small footprint”, says Express Logic. The X-Ware IoT platform automatically scales to use only what is needed by the application, making it suitable for the smallest low-power IoT devices.

ThreadX, FileX, and NetX Duo have attained a range of safety certifications. They include IEC 61508 SIL 4, IEC 62304 Class C, ISO 26262 ASIL D, EN 50128 SW-SIL 4, UL 60730-1 Annex H, CSA E60730-1 Annex H, IEC 60730-1 Annex H, 60335-1 Annex R, and IEC 60335-1 Annex R, 1998.
