Commercial 4 G, mobile phone upload and download data rate slow problem has been A certain degree of relief, the focus of concern of the industry gradually transferred to local area wireless communication and control field, such as bluetooth Mesh, WiFi, Zigbee and 2.4 G RF, but global mobile operators for the next generation of LTE higher data rate - A Pro and 5 G cellular network communication technology high interest has no reduction, for example, American mobile operator Verizon 8 to 9 different locations in the last month of 5 G field test for more than 1 Gbps data transfer rate, and plans to mobile hotspot and fixed wireless (fixed wireless) as its early application of 5 G wireless technology.

Market Research firm Juniper Research company recently has 5 g market prospect made a visionary predictions: while the first 5 g commercial deployment is expected in 2020, but by 2025, 5 g adoption is very common. By 2025, the global 5 g services revenue is expected to top $65 billion, compared with its commercial operation in 2020 to $100 million in the first, and operator services will account for 2025 about 7% of its total.

In 2 g, 3 g and 4 g Modem market steady qualcomm of their market in recent years has been to develop LTE - A Pro Modem, is publicly announced last February to develop the industry's first rate reaches 1 GBPS of LTE - A Pro Modem. Industry insider, the Modem engineering of qualcomm samples will be until the second half of 2016 to the market, production until 2017.

Pro and 5 g LTE - A Modem need 5 carrier aggregation technology, which will bring huge challenges of Modem control because of the need to each carrier to perform measurement, calibration and other processing functions, and often need to deal with two units at the same time, increase the complexity of the receiving link control. Also, since Pro and 5 g LTE - A Modem is to different formats in the Modem integrated into A Modem, so you need to be able to efficiently fusion, 3 g, LTE - A td-scdma and 2 g software solutions, and ultra low delay to move from one format to another format.

Next generation LTE - A Pro and 5 g modem baseband implementation of 3 big challenge can be summarized as follows: first, how to arrange the modem PHY (physical layer) is the challenge of A very headache, because you need real-time scheduling many accelerator, processor and the coprocessor, very mechanism is needed to arrange the location of the PHY devices automatically, in the premise of no additional costs to achieve very low time delay; Second, the complexity of speech processing in rapid growth. Compared with the traditional codec, ((EVS) increased the complexity of the 4 to 5 times, not only such, power consumption has a very tight budget and card, and the memory demand has increased by 10 times compared with AMR; Third, the modem must be an ultra-low power design. First of all, the machine must be competitive on the battery service life, this increases the complexity of design, secondly, must be idle cycles of modem design special deep sleep mode.

CEVA recently launched CEVA - X4 processor IP is the perfect solution of the above design challenges, it is also the world's first LTE - A Pro and more than 5 g modem standard PHY control processor IP development. It integrates was applied to control the PHY layer control processing and advanced DSP processing ability, and adopted the extensible VLIW and SIMD instructions architecture to support the fixed point and floating-point processing operations.

CEVA marketing vice President Eric Briman pointed out: "compared with the previous generation products, CEVA - X4 processor IP will be promoted double DSP processing performance, power consumption was reduced by 50%, the control performance improvements for three times. CoreMark/MHz standards control test results is 2 times of qualcomm products."

CEVA - X4 and CEVA - XC4500 processor IP cooperate when using, can make the next generation LTE - A Pro and 5 g modem implement the following properties: 1) the carrier may achieve 100 MHZ bandwidth; 2) downstream data rate reached 1.2 Gbps; 3) 220 MBPS uplink rate; 4) Modem run multiple formats at the same time, realize the dual SIM card, acer stations and small household base station connected at the same time, 3 g calls downlink LTE - A Pro data at the same time; 5) extensible architecture to support the upcoming Rel. 14 version (support 32 carrier).

CEVA is the world's supply of baseband processor IP market leader, is also the first DSP IP cellular baseband global suppliers. Eric Briman said: "out of every three smartphones globally in 2015 with A baseband IP CEVA is adopted, CEVA is the world's first LTE/LTE - A DSP IP vendors have yielded more than 20 design (winning), CEVA can provide complete LTE - A, LTE, td-scdma and WCDMA baseband IP and 2 g. CEVA current trademark customers with samsung, Intel, core technology and spreadtrum."

CEVA baseband IP authorized suppliers are: mediatek, new coastline, spreadtrum, via, zte, samsung, Intel, core technology and CYIT.
