Mentor Graphics Announces Support for the Multi-threaded MIPS32 34K Core with the Nucleus SMP RTOS

Mentor Graphics Corporation (NASDAQ: MENT), with its flagship
Nucleus® Real Time Operating System (RTOS), today 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 combination demonstrated
increased embedded application performance of over 20%, without
increasing power consumption or silicon size. The Nucleus product
is the industry’s first RTOS to demonstrate significant performance
gains using MIPS Technologies’ Virtual Processing Engines (VPEs)
over a single-core approach.
The balance between increased performance and power consumption
for connected devices is becoming more delicate as multicore
devices are deployed. Increased silicon area, heat dissipation and
power usage are typical trade-offs associated with multicore
devices in order to achieve performance increases. Through the
combination of MIPS’ multi-threaded architecture and SMP support in
the Nucleus RTOS, Mentor succeeded in increasing performance by
using two hardware threads, or Virtual Processing Elements (VPEs),
versus a single-core approach. The performance increase of more
than 20% was demonstrated using EEMBC CoreMark, a simple, yet
sophisticated benchmark designed specifically to test the
functionality of a processor core.
The Nucleus RTOS provided the software framework for symmetric
multiprocessing (SMP) that 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.
“We are pleased that Mentor recognizes the advantages of
multi-threading, and is supporting our multi-threading technology
with its Nucleus RTOS which has widespread adoption in mobile,
networking and a variety of embedded applications. Nucleus VSMP for
the 34K core can enable developers to achieve significant
performance efficiency benefits,” said Gideon Intrater, vice
president of marketing, MIPS Technologies.
“Mentor’s Nucleus RTOS continues to be one of the most highly
deployed in the industry due to its reliability, efficiency and
power management capabilities,” said Andrew Caples, Nucleus product
line director, Mentor Graphics Embedded Software Division.
“Together with MIPS’ 34K core, Nucleus provides embedded developers
with system performance gains at a much lower cost.”
Used in more than 2.3 billion mobile handsets, 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.
