China 4G boost: multi-mode multi-frequency and 64-bit is the hotspot of this year's processor

In 2014, with the rapid spread of LTE in the world and the issuance of 4G licenses in China and Apple's first use of 64-bit chips on the iPhone, multi-mode multi-frequency and 64-bit chips will undoubtedly become a hot spot in the mobile industry this year.

Experience improvement is the main cause of manufacturers preparing for 64-bit

As we all know, in the past 2013, the use of 64-bit processors in mobile phones is only Apple, and this pattern will be broken next year. In fact, Qualcomm released its first 64-bit processor, Qualcomm Xiaolong 410, at the end of 2013, targeting the low-end market. It is expected that at this year's CES show, Qualcomm will also release a 64-bit processor for the flagship model. Samsung, also a processor manufacturer, is naturally not far behind. Samsung has publicly stated that it will also have 64-bit processor phones this year.

GfK data shows that the current smart phone market, dual-core, quad-core processor share has been more than half, Samsung, MTK and other manufacturers are pushing the eight-core processor into the market, the launch of A7 64-bit chip in iPhone5S for the mobile phone industry chain hardware competition A new idea, Samsung, Qualcomm and other manufacturers will shift the energy of smart phone hardware upgrade to 64-bit processor. In the Android ecosystem, smart terminals equipped with 64-bit processors may become a new direction for the development of the high-end market. And Google claims that its Android system is already a 64-bit system, only to be supported by 64-bit chips.

In addition to the ARM camp's many manufacturers are gearing up, another camp, the Intel X86 camp is not sitting still. At the Intel Developer Conference in San Francisco in September 2013, Intel has announced the addition of 64-bit chips to the Android platform. Namely the Intel Atom Z3000 processor family codenamed "Bay Trail-T", Intel's first mobile multi-core system chip, the most powerful product for tablet and mobile devices.

According to the reporter, the series has dual-core and quad-core. The most powerful 4-core Z3770 will support a clock speed of 2.4GHz and a resolution of 2560x1600. It is expected that Intel will release the 64-bit Bay Trail processor ahead of schedule.

In this regard, Wang Yanhui, secretary general of the China Mobile Alliance, believes: "I believe that all AP suppliers are developing 64-bit processors. This year, Android high-end mobile phone sales point is undoubtedly 64." In short, the 64-bit computing smartphone battle is about to open.

In addition to vendor competition considerations, the introduction of 64-bit chips provides a new direction for smartphone performance and user experience improvement. In the long run, it is critical to improve the overall smartphone industry and user experience.

"From the perspective of the overall smart phone industry, the trend of smart phone integration with terminals such as tablets and smart TVs is becoming more and more obvious. Mobile terminals are closer to PC-level computing power, which will greatly enhance the processing power of multi-screen interaction of smart phones. Promote the development of the smart phone industry, promote the synergy of multi-screen smart terminals and the integration of the industry chain; from the user's perspective, the current smart phones take on more and more "production" functions, shooting higher-definition pictures and Video, more experience games, and stronger processor performance will bring more functions and experiences to mobile terminals.” Wu Faifeng, an analyst at GfK China, told reporters.

Comprehensive consideration of 64-bit progressive development

The direct benefit of 64-bit chips is the growth of mobile phone memory. In the long run, the increase in mobile phone memory is inevitable, but the technical obstacles of the processor must be solved first. At present, the memory of high-end smartphones is mostly 1GB and 2GB. The memory of previous generation iPhones has been upgraded from 256MB to 1GB for three years. In the next three years, it is possible to see the memory of smart phones over 4GB. The key lies in energy consumption. And battery improvements, and Apple solved the technical barriers on this processor in advance, laying the foundation for future performance improvements, the operating system and App will be fully applicable to the A7 processor.

However, some insiders have raised their own objections. In the PC industry, for example, Windows XP has a 64-bit version since its introduction in 2001, but it is not popular. By 2010, the proportion of 64-bit systems used in Windows XP systems was less than 1%. The proportion of PCs using Windows 7 systems using 64-bit systems is 46%, and the computer industry has experienced 10 years of development. In the consumer market, 64-bit systems are not mainstream, or for most ordinary consumers. Products that require too much performance. Apple executive Phil Schiller said at the press conference that the information industry has been transitioning from 32 to 64 years, and Apple has completed it in one day. The development of product parts and components is likely to be completed in a short time, and the market demand? The evolution of smartphones from 32-bit to 64-bit is unlikely to be faster than the PC industry.

“Although many manufacturers are eager to try, 64-bit chips need to be truly popular on smartphones. Therefore, Wu Xiaofeng told reporters: “The development of smart mobile terminals requires stronger performance, richer functions and user experience. Currently, smart phone chip makers are pushing smart phone chips to move toward eight cores. The 64-bit processor provides a new evolution direction for the development of the smartphone industry and accelerates the overall performance of smartphones. From the perspective of industrial development, on the one hand, the evolution of the overall industrial chain requires the overall promotion of the overall industrial chain and manufacturers such as manufacturers, operating systems, and application development; on the other hand, the competition for hardware performance requires more consideration of power consumption factors. How to balance performance and power consumption on mobile devices is also a key factor to measure. Wu Xiaofeng told reporters.

In addition to the support of the industry chain, the improvement of the smartphone user experience by the 64-bit model is limited.

In this regard, Qualcomm related sources told reporters: "Smartphones to complete fast, stable 4G LTE connection, ultra high definition (4K) video capture and playback, high-definition audio, advanced digital camera features, fast web browsing and seamless video streaming, etc. This requires ensuring that the entire SoC is optimized, not just the CPU, to ensure the best balance between performance and power consumption. Although CPU specifications are a concern, in a modern mobile SoC, the CPU only accounts for about 15%. The remaining 85% of Qualcomm's Opteron processors are made up of a number of dedicated, diverse engines, including the industry's most advanced 4G LTE modems, Adreno GPUs, and low-power Hexagon DSPs. The diverse engines efficiently handle different applications. Work tasks to enhance the user experience and ensure ultra-low power consumption."

LTE boosts multi-mode multi-frequency Qualcomm leadership continues

In addition to the above-mentioned 64-bit chips will be the hot spot for manufacturers this year, with the issuance of domestic TD-LTE licenses, as of now, there are 23 TD-LTE commercial networks deployed in 18 countries around the world, and more than 40 In the planned deployment of commercial networks, the global user scale has exceeded 5 million. The TD-LTE Global Development Initiative initiated by China Mobile has successfully brought together 80 operators and 63 industry partners from around the world to form a considerable scale of operations. The TD-LTE industry chain has begun to take shape with the cooperation platform of merchants and manufacturers.

According to statistics, the coverage of global LTE commercial networks is gradually improving, and the demand for LTE terminals (mobile phones, tablets, and data cards) is becoming more and more urgent. Last year, global mobile phone chip manufacturers including Qualcomm, Broadcom, NVIDIA, and ST-Ericsson launched related LTE products. It can be said that the outbreak of LTE terminals is not far away. MediaTek and Spreadtrum, which compete in China's smartphone market and Qualcomm, are also actively deploying, focusing on multi-mode LTE products integrating TD-LTE and FDD-LTE.

According to the reporter, the most mature 4G LTE full-mode chip (G/G/E/W/TD/TD-LTE/FDD) solution is Qualcomm, the second is Ericsson, and the next is Huawei's HiSilicon. In terms of shipments, Qualcomm and HiSili are top 2 manufacturers of global shipments of LTE chips. The chips are doing well, and they are also close chip partners of LTE on Huawei terminal companies. Hisilicon's chips have also been shipped in large quantities in global markets such as Japan, Europe, China, Asia Pacific and Latin America.

The new PXA1088 LTE chip is the industry's first quad-core "5-mode 13-band" Category 4 LTE single-chip solution for the mass market. Lianxin has also launched the quad-mode 11-band TD-LTE/LTE FDD/TD-SCDMA/GGE baseband chip LC1761.

In the face of the upcoming 4G market, Intel will also provide leading low-power, global modem solutions that can support multiple frequency bands, multiple regions and multiple devices as its important strategy. A single RF chip has been introduced to support 15 simultaneously. XMM7160 multi-frequency multi-mode platform in the FDD-LTE band.

"Although multi-mode multi-frequency is not necessarily the real demand of most consumers, mobile chip manufacturers will support the future launch of chips from the cost considerations. At present, Qualcomm stands out. With the addition of MediaTek and Spreadtrum in 2014, market competition will gradually become reasonable. Breaking the Qualcomm monopoly situation, but the actual formation of a number of competition is estimated to be in 2015." Wang Yanhui predicted the multi-mode multi-frequency chip competition.

The challenge is still multi-frequency and multi-mode

According to the reporter, at present, in the multi-mode frequency band, different countries have different frequency bands. This leads to the high requirements on the technology of the terminal equipment due to the need to support LTE and 2G, 3G multiple modes and multiple frequency bands, and needs to support nearly 17 different frequency bands; on the other hand, for different countries and How to coordinate resources between bands between regions.

“With regard to multi-mode multi-frequency, the industry generally believes that the band is not unified is the biggest obstacle to the global LTE terminal design. Currently, the diversity of global 2G, 3G and 4G LTE network bands poses a challenge to mobile terminal development. Global 2G and 3G technologies Each uses 4 to 5 different frequency bands, plus 4G LTE, the total number of network bands is nearly 40." Qualcomm related sources told reporters.

In addition, support for multiple technical parameters, backward compatibility of technology, and reduction in power consumption and chip area are challenges that chip vendors have to deal with. For example, LTE technology requires chip products to support different frequency bands to meet the needs of LTE network standards and frequency bands in different countries and regions. At the same time, chip products are also required to adapt to various antenna system standards, such as 2X2 MIMO and 4X4 MIMO.

In response, Wang Xiang, senior vice president and president of Qualcomm Wireless Semiconductor Technologies, told reporters: "In response to the above challenges, Qualcomm has released the RF360 RF front-end solution, which is the first in the world to integrate all 40 frequency bands. Together with the RF front-end chip, the terminal manufacturer has the opportunity to make a mobile phone a global roaming mobile phone, which simplifies the most troublesome power consumption and area short-circuit faced by many engineers in mobile phone design. Due to the support of more than 40 frequency bands, it is necessary to occupy a very large PCB area, and the design of the antenna brings technical bottlenecks. However, through the Qualcomm RF360 front-end solution technology, the terminal manufacturers have significantly reduced the introduction of LTE terminals. Technical thresholds and design difficulties shorten the time-to-market of terminals and increase the competitiveness of terminal manufacturers."

"Multi-mode multi-frequency dependent chip manufacturers upgrade, currently MediaTek, Spreadtrum will be behind Qualcomm for about a year. This is mainly because Qualcomm is investing in LTE much earlier than MediaTek and Spreadtrum, but with the gradual removal of technical obstacles, It is only a matter of time before the companies such as MediaTek and Spreadtrum are multi-frequency and multi-mode." Wang Yanhui told reporters.
