As datang telecom technology co., LTD. (hereinafter referred to as datang telecom) core enterprise in the field of mobile communications chips, al core technology was introduced in 2015 4 g LC1860 intelligent terminal baseband chip, with its excellent performance, power red rice 2 a phone for breakthrough tens of millions of sales, the industry consensus. 2016 united core technology develops strives for perfection the spirit of craftsman in intelligent terminal application as the core, to the car networking, intelligent household, unmanned aerial vehicles, robots, AR/VR in areas such as further extension. Recently, the core technology to launch domestic first 64 LTE Cat6 SDR LC1881 SoC chip.
As the domestic first 64 commercial SDR chip, LC1881 is following LC1860 launched the first support 64 LTE Cat 6 SDR SoC chip, has the milestone significance. It not only has high integration, easy to expand, the advantages of the wide band, low power consumption, strong computing power and communication capacity, but also a scalable, can be cut, customizable chip products.
LC1881 leading LTE SoC chip architecture design, integration of the AP and the Modem, can significantly improve chip integration and reducing power consumption and cost. CPU adopts unique eight nuclear architecture (A53 size nuclear architecture design, can according to different data processing load, flexible eight nucleus or only a small call, have great power consumption advantages. LC1881 SDR software radio technology adopted, for example, at the same time vector and the combination of the general DSP processor architecture, strong ability in data parallel access and super computing ability, in order to achieve the SDR technology provides a good platform for the support. When applying LC1881 into new areas, only need to program corresponding to the field of all kinds of processing, don't need to design a new hardware accelerators, also do not need to flow again.
As people quality of wireless communications, data transmission rate of the demand is higher and higher, carrier aggregation (CA) as one of the important technology of LTE - A, has in the spectrum, and integration of cross spectrum characteristics of the wireless channel. LC1881 USES 2 x 20 pairs of carrier aggregation, descending rate of 300 MBPS, support (. After application of carrier aggregation (CA) technology, 4 g networks like lane became a multi lane, the Internet speed is exponentially increase.
With the development of mobile Internet, mobile video into full hd era. LC1881 new h. 265 codec technology, the technology can be implemented using 1 MBPS ~ 2 MBPS transmission speed transmission 720 p resolution (1280 x 720) ordinary hd audio and video transmission, compared to the h. 264, more can save bandwidth. Under the same image quality, h. 265 video size will be reduced about 39% ~ 44%. In bit rate decreased by 51% ~ 74% of cases, h. 265 video coding quality also with h. 264 video coding approximate even better, watch online video will have higher quality.
At the same time, LC1881 can support FHD full hd image display. Also escalated on image processor, can support dual 1080 p video, the addition of PDAF phase focus with hardware HDR high dynamic range technology can greatly improve the user experience taking pictures.
On the peripheral interface, LC1881 from usb upgrade to start. USB2.0 maximum transmission bandwidth is 480 megabits per second, and the maximum transmission bandwidth start up to 5.0 Gbps. See the faster transmission speed, more powerful power transmission. And new Type - C solves the worldwide problem of USB plug forbid forever, to achieve both the inserted at will.
In the future, core technology will follow the new trend of the technology, hand in hand cooperation partners launched landmark consumer electronics products, at the same time based on SDR technology platform, in the industry, continuously expand in areas such as automotive, industrial robot, service "Internet + made in China" national strategy.
