San Jose, Ca. - MIPS Technologies and SySDSoft Inc. have teamed up on what they claim is the first port of the wirekess LTE protocol stack ported to the Android mobile platform.

Benchmarks of the SySDSoft LTE protocol stack running on MIPS-Based Android and Linux platforms achieved nearly theoretical maximum CAT4 data throughput with small packet sizes, low CPU operating frequency, and low power.

With higher upload/download throughput and similar or better performance compared to the competitive solution running at 500MHz, these are believed to be the highest-performance results for such small packet sizes running on a 350MHz core.

“As LTE gains traction in mobile handsets, Android will become increasingly important, and the processors driving those systems must be powerful enough to run the entire software stack and applications on a single processor,” said Khaled Ismail, CEO, SySDSoft.

SySDSoft’s LTE UE software stack was tested with both Linux and Android operating systems on a MIPS-Based chipset featuring a 350MHz MIPS32 24Kf CPU core.

The benchmark tested packets of various sizes using an eNodeB emulator to demonstrate achieved UE performance complying with CAT4 requirements. Results showed 150Mbps download (DL) and 50Mbps upload (UL) data rates for packets as small as 256 bytes. For 128byte packets, results showed throughput of around 100Mbps DL and 50Mbps UL thus achieving CAT3 even under such stringent conditions.

The benchmarks demonstrate high performance with minimal processor MIPS consumption, averaging 95 MIPS. This performance was achieved on both Linux and Android without any code changes between the operating systems—demonstrating the versatility of the LTE UE stack architecture.
