Mentor Graphics’ Nucleus SMP RTOS Supports Multi-threaded MIPS32 34K Core

Mentor Graphics announced the Nucleus product integration and SMP (symmetric multiprocessing) support for the MIPS32 34K core that utilizes MIPS Technologies’ MT (hardware Multi-Threading) technology. The combined technology increases embedded application performance by over 20%. In addition, it does this without increasing power consumption or silicon size. Nucleus RTOS with MIPS’ 34K core provides embedded developers with system performance gains at a much lower cost.

Thanks to MIPS’ multi-threaded architecture and SMP support in the Nucleus RTOS, Mentor Graphics increased performance by using two hardware threads, or Virtual Processing Elements (VPEs), versus a single-core approach. The performance increase of over 20% was demonstrated using EEMBC CoreMark, which is a benchmark designed specifically to test the functionality of a processor core.

The Nucleus RTOS provided the software framework for symmetric multiprocessing (SMP). It includes load balancing, task and interrupt affinity, conditional bound computation, and full support for the multiple hardware threads on the same CPU core. The performance gains can be leveraged for a wide range of systems including mobile and machine-to-machine (M2M) applications.

The Mentor Embedded Nucleus product is a proven, highly efficient, and reliable operating system. The Nucleus RTOS delivers high performance while optimizing resource usage in a single-OS or multi-OS platform. Built with a framework for high efficiency and power management, the Nucleus RTOS is ideal for memory resource-constrained devices and for systems where maximizing cycles-per-watt to conserve power is critical.
