Lattice Semiconductor revealed that its new iCE40 LM FPGA has been integrated into the new Huawei P8 flagship smartphone to achieve optimal 4G reception. Huawei will continue to use its Kirin 930 chipset to use Lattice's low-latency, tunable antenna controller in other devices.
Huawei P8's Signal + technology uses iCE40 LM FPGA to automatically optimize 4G reception for multiple RF conditions. The final antenna solution is 80 times faster than other solutions. In high-density cities and rural areas with limited reception, poor coverage or crowded RF environments often occur, the reception quality is 40% higher than Huawei's competitors.
Huawei has invested a great deal of effort in designing the P8's attractive all-in-one aluminum body. Lattice's tunable antenna controller helps it achieve the best RF performance and overcomes the RF quality problems inherent in metal cases. The company said that the iCE40 LM device acts as a bridge between the Kirin 930 application processor and the tuner integrated circuit to minimize wait times during antenna switching and also save system power consumption.
Subra Chandramouli, Lattice Marketing Director, said: "We designed the iCE40 LM to provide our partners with maximum flexibility to design consumer devices with limited space." Huawei has shown that users don't have to choose a beautiful device Sacrifice functionality. "
