Qualcomm, Broadcom, Intel snatch cake
The domestic 4G market is accelerating, and licenses may be issued before the end of the year. On the eve of the 4G curtain, mobile phone chip makers are eager to try, this huge market cake makes people salivate. Especially foreign chip manufacturers want to grab more shares with their own technological advantages. At a time when domestic manufacturers have a headache for the five-mode 10-frequency, Qualcomm has launched a seven-mode full-coverage chip product, which is not good news for domestic chip manufacturers.
Industry worried about Qualcomm's dominance
The RF360 front-end solution introduced by Qualcomm at the QRD (Qualcomm Reference Design) Summit, for the first time, realizes the design of a single terminal supporting all LTE standards and frequency bands, and supports seven network standards (FDD, TD-LTE, WCDMA, EV-DO, CDMA 1x , TD-SCDMA and GSM / EDGE). Roger, senior vice president of product management at Qualcomm Technology, said that according to Qualcomm ’s current design plan, three cards and three standbys, or even four cards and four standbys can be achieved in mobile phones, and partners can design card slot assignments in products at will.
This means that in the future market where 4G and 3G coexist, switching between various modes will become easier. The only worry is the price of these products. At the QRD summit site, a person in charge of a mobile phone manufacturer told the "IT Times" reporter without worries that most of the patents were in the hands of Qualcomm, resulting in expensive chips supporting multiple models.
Broadcom is also a frequent action. Michael Severo, senior director of Broadcom's product marketing, told the "IT Times" reporter that Broadcom has launched an LTE chip model BCM21892, which is 35% smaller than other solutions in the industry and supports TD-LTE and FDD. -LTE, HSPA +, TD-SCDMA, EDGE / GSM five modes.
Foreign chip manufacturers act frequently, but domestic manufacturers are relatively calm. According to this development trend, foreign chip manufacturers will occupy the dominant position in the domestic TD-LTE terminal chip market, which is also a matter of considerable concern for people in the industry.
Intel carries 22nm counterattack
Although it only has a 2% share in the mobile chip market, in terms of technology, Intel is not at all Qualcomm. Intel said that the 22nm-based chipset has already been used in tablets and ultrabooks. In the second half of this year, the 22nm mobile phone chipset will also be available. Compared with Qualcomm's current 28-nanometer process, it can reflect the advantages of the process.
At the same time, chip performance has once again become the focus of competition among manufacturers. Qualcomm Snapdragon ’s latest 800 processor supports 4k ultra-high-definition video playback and shooting, using DTS-HD and Dolby Digital enhanced audio, supports up to 55 million pixel camera and up to 2560 & TImes; 2048 screen resolution, and 1080p HD Miracast wireless display.
In addition to combining 5G WiFi, globally certified NFC technology and advanced indoor positioning technology, Broadcom ’s VideoCore multimedia supports “dual HD†function, providing synchronized HD output for smartphones and Miracast-capable large screens (such as TVs) and many more.
Reducing chip energy consumption is the main target
Energy consumption has become the biggest "heart disease" of smartphone users, and they hope to achieve a balance between performance and power consumption. 4G, multi-mode and constantly improving chip performance are a huge test for energy consumption.
In this regard, Michael Sivello from Broadcom said that the Broadcom chipset uses a new "wave peak energy control technology", which will automatically adjust energy consumption according to the size of the mobile phone signal. Qualcomm mainly promotes fast charging technology. Roger said that on the Snapdragon 200 and future processor platforms, its power consumption will be 30% lower than competitors, and the use of the latest fast charging technology when charging can also shorten the charging time. Double.
Intel is also working hard to balance power consumption and performance. A person in charge of Intel introduced that in the case of the same power consumption, the calculation rate of Intel mobile chips is higher than other competitors. At the same time, Intel's "Core Frequency Technology" has been applied to mobile phones, and the CPU will quickly increase the main frequency according to the current task volume; after the task is completed, it will quickly return to the low frequency state to save energy consumption.
Chen Rongkun, vice president of Intel ’s product architecture division and general manager of China ’s mobile communications division, told the "IT Times" reporter that there is now a common misconception that there are some inherent energy efficiency issues in the X86 instruction set. In fact, the impact of the instruction set on power consumption is negligible, and the microprocessor architecture is the key to determining the "per-watt performance ratio" indicator. The specific implementation of ARM and X86 is just a design point optimized for different performance levels. "The future trend is that applications will increasingly demand mobile phone performance, and ARM will also have its own problems. If performance is improved, ARM will also encounter great difficulties in power consumption. Therefore, Intel and ARM are Doing things in two directions, the challenge for Intel is how to reduce power consumption while ensuring high performance; ARM's problem is how to improve product performance under the same power consumption situation. "Chen Rongkun said.
It features small size, high reliability, cheap cost and good channel-to-channel uniformity, and is widely used in PON networks to realize optical signal power splitting.
