MIPS Technologies and SAI Technologies Demonstrate Performance Benefits of Multi-Threading for LTE Systems
28 February 2012 - 7:01PM
MOBILE WORLD CONGRESS -- MIPS Technologies, Inc.
(Nasdaq:MIPS), a leading provider of industry-standard processor
architectures and cores for digital home, networking and mobile
applications, and SAI Technology, a leader in secure wireless
communications technologies for the worldwide mobile wireless
market, announced that they achieved a performance increase of over
65% across various packet sizes when leveraging MIPS'
multi-threaded technology running SAI's LTE Protocol Stack for User
Equipment (UE) terminals. The results demonstrate how utilizing two
threads, or Virtual Processing Elements (VPEs), rather than a
single thread, can dramatically improve the efficiency of baseband
processing in mobile devices such as smartphones and tablets.
For many of today's smart, connected consumer devices, it is a
common strategy to leverage multiple cores to achieve the high
performance and Quality of Service (QoS) needed. But leveraging
multiple cores can lead to an increase in silicon area and power
consumption. For many applications, an additional or alternative
strategy is to leverage multi-threading technology, which can
provide a significant performance boost without a significant
increase in die size or power consumption.
For this demonstration, SAI leveraged its system-level expertise
in mobile applications to identify the best way to partition the
control plane and data plane elements of the LTE baseband stack
across the two virtual processors, or threads, in the MIPS core.
The results collected by SAI on the hardware platform, which
emulates a complete mobile network passing triple-play (voice,
video and data) traffic, suggests that the combination of the MIPS
core and SAI stack can support CAT 1 to CAT 4 performance in LTE
user equipment with very efficient area and low power in a
single-core footprint.
"MIPS' patented multi-threading technology provides clear
performance benefits for a wide range of systems. This latest
achievement demonstrates the benefits of multi-threading for mobile
devices, and we anticipate that the benefits can scale to base
station solutions as well, particularly in the burgeoning small
cell equipment area and machine-to-machine (M2M) devices. We are
pleased to team with SAI to enable customers who leverage MIPS'
multi-threading technology and SAI's LTE solutions to build a
better baseband," said Gideon Intrater, vice president of
marketing, MIPS Technologies.
"Our complete solution complies with the latest LTE
specification, has completed interoperability testing, and has
already been approved for use with a major carrier. With our
solution running on the MIPS multi-threaded core, we achieved a
significant performance boost that was virtually 'free' in terms of
die area and power consumption. This solution can be a powerful
differentiator as companies develop next-generation 4G mobile
devices, and with the production-ready solution, companies can gain
a time-to-market advantage," said Dr. Venkat Rayapati, CEO, SAI
Technologies.
About SAI's LTE Protocol Stack
The SAI LTE Protocol Stack is implemented for User Equipment
(UE) terminals compliant to the 3GPP Release 8 and Release 9
specifications. It consists of a fully optimized for Layer 2, Layer
3 and NAS LTE protocol software, enabling high uplink and downlink
data rates supporting Cat-1 to Cat-4. The module has been
integrated and validated with IOT with multiple third-party
commercial processors and solutions. The architecture is designed
to be scalable and portable to different hardware platforms and
operating systems with optimum processor utilization and low memory
footprint. SAI's LTE UE and eNB stacks support today multiple
operating systems: Linux, Android, Vx Works etc. The LTE protocol
stack is supported by a suite of advanced development, test and
verification tools to enable rapid product development. SAI also
provides dedicated support and customization services to assist
with porting, integration and end-to-end LTE system verification
from lab tests to field trials.
