LTE and LTE Advanced Baseband Processing Get Performance Boost From MIPS(R)
Multi-Threaded Cores

Imagination Technologies Joins With SAI Technology and Mentor Graphics to
Demonstrate User Equipment Reference Platforms at Mobile World Congress

Imagination Technologies (LSE:IMG), a leading multimedia, processor,
communications and cloud technologies company, announces that its
multi-threaded MIPS®* processor cores show significant performance benefits
compared to single-threaded platforms for LTE baseband processing in user
equipment (UE) such as mobile handsets and tablets. Results were achieved on
reference platforms for both LTE and LTE Advanced, which will be demonstrated
at Mobile World Congress, being held February 25 – 28, in Barcelona, Spain.

Leveraging the power-efficient MIPS multi-threaded cores, Imagination and SAI
Technology achieved a performance increase of 45% over a single-threaded
platform when executing SAI's LTE Advanced software stacks on SMP Linux**. As
the next major milestone in LTE evolution, LTE Advanced signifies a dramatic
increase in network capacity and considerably higher data rates enabling high
bandwidth, media-rich services to be delivered to residential and
business/enterprise users. Designers of next-generation systems such as
picocells, femtocells and advanced handsets can leverage the MIPS-Based™
multi-threaded solution—which supports new LTE Advanced Release 10 features
including carrier aggregation, as well as MIMO, EMBMS and Voice-over-LTE
(VoLTE)—to build high-performance, low-power products.

Imagination is also teaming up with SAI and Mentor Graphics to create an
integrated multi-threaded solution for 4G LTE. The solution will include
multi-threaded MIPS processor cores, the popular Mentor Nucleus® VSMP Real
Time Operating System (RTOS) and LTE software stacks from SAI that are
optimized to take advantage of multi-threading. For LTE systems such as
dongles, smartphones, tablets, and high-volume embedded devices within the
'Internet of Things,' the MIPS-Based multi-threaded solution can enable
designers to build products with advanced real-time capabilities, low power
consumption, and high performance.

Both the LTE and LTE Advanced reference platforms highlight the benefits and
feasibility of integrating the solution elements into production 4G systems.
Imagination's proven multi-threaded MIPS processors, including the popular
MIPS® 34K™ core and the latest generation interAptiv™ multiprocessor, are
available for licensing today. Designers can get a head start on creating a
broad range of highly performance-efficient LTE systems by leveraging
multi-threaded MIPS cores together with SAI's verified software stacks for LTE
and LTE Advanced Systems, as well as industry-standard SMP Linux and Mentor
Graphics' Nucleus RTOS. Companies can also benefit from the scalability of the
solutions, leveraging common tools and architecture for development across a
wide range of mobile and wireless systems.

"We have always understood the unique benefits of hardware multi-threading for
mobile and wireless applications. Indeed, that was one of the attractions that
MIPS offered Imagination. Thanks to our partnerships with SAI and Mentor, we
can now demonstrate how this translates into competitive advantage for LTE
systems. These solutions are showpieces for the performance efficiency of the
MIPS architecture."

                     —Tony King-Smith, EVP marketing, Imagination Technologies

"Embedded developers can achieve gains in system performance at a much lower
cost with the combination of Imagination's multi-threaded MIPS processors,
SAI's LTE protocol stacks, and Mentor's Nucleus RTOS. We see particularly
exciting opportunities for this combined solution as internet connectivity
spreads to everyday devices and LTE becomes standard across many embedded IoT
devices. With Nucleus, developers can take advantage of advanced power
management capabilities from one of the most highly deployed real-time
operating systems in the industry."

       —Scot Morrison, general manager of Embedded Runtime Solutions at Mentor

"As OEMs continuously look for ways to differentiate and get products to
market more quickly, we are pleased to work with Imagination and Mentor to
show how companies can attain differentiation through the performance and
efficiency benefits of multi-threading, and also to deliver proven reference
platforms to enable them to quickly create next-generation LTE systems."

                               —Dr. Venkat Rayapati, CEO, SAI Technology, Inc.

About the Mentor Nucleus RTOS

Used in more than 2.3 billon 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. For further information on the new Nucleus-based technologies, visit

downlink data rates supporting Cat-1 to Cat-4 and higher. The SAI LTE Protocol
Stack Architecture is designed to be modular, scalable and portable to
different hardware platforms, and multiple operating systems (Linux, Nucleus,
Android, Vx Works) with low CPU utilization and small memory footprint. SAI
provides design services and customization for porting, integration, IOT,
customization to build LTE products for customers. SAI provides LTE UE and eNB
small cell PHY, protocol stacks and radios to enable complete system products.

Editors Notes

*MIPS is now part of the Imagination Technologies Group.

**Performance scaling for the UE platform was measured on the miniature
LTE-Advanced network test bed by comparing total throughput (uplink plus
downlink traffic) on one thread/VPE versus total throughput on 2 threads/VPEs
when running the SAI stacks. Traffic was comprised of a mix of video, voice
and data as generated by video servers, VoIP phones and network traffic
