FPGAs will play an important role in 3G/4G era

Xilinx invented the programmable logic device 26 years ago. Now, Xilinx's products are already in the wireless infrastructure, especially in the deployment of domestic TD-SCDMA. An important value of FPGA is that it provides time guarantee for operators to quickly bring products to market, and the programmability of FPGAs makes it possible to upgrade the next generation of products at a low cost even after the completion of 3G network deployment and provide differentiation. Value-added services. FPGAs that are highly integrated with parallel DSP processing capabilities can also replace ASICs/ASSPs in BBUs, RRUs, PTNs, GPON/EPONs, and 40G/100G Ethernet networks with significant cost and power consumption advantages.

The cost is very important to operators, especially the Chinese market. Xilinx helps operators to optimize costs in three ways. The first is to provide a unified standard platform. The unified standard can support LTE, WiMAX, WCDMA, CDMA2000, TD-SCDMA and GSM. Second, the product life cycle. Many standard devices have a life cycle and will stop production at some point. Compared to standard devices, FPGAs have a long life cycle, which is very important for wireless device manufacturers, which means that there is no need to re-purchase new devices, and it can significantly save investment. Third, capacity expansion. In base station deployment, capacity expansion can be achieved through optimization, while the standard device capacity is fixed. Programmable logic can not only increase the capacity, but also can flexibly support different standards, or a certain part of the implementation of a standard.

In the field of TD-SCDMA, all well-known TD-SCDMA operators use Xilinx products. As the only senior member of programmable logic in the TD-SCDMA technology forum, Xilinx and the related leaders and companies of the forum will jointly work together to promote China's TD-SCDMA and future evolution.

In the next five years, the trend of the communications market will become more and more pressing with high bandwidth, low power consumption, low cost, high performance, ever-changing standard coexistence, compatibility, scalability, and time to market.

With the deployment of 3G deployment, the smooth transition to 4G is a major trend in the field of wireless communications. Speed ​​up 40G/100G deployment in subways, backhaul lines, and core networks to meet the needs of triple play. With the continuous penetration of domestic communications operators in overseas markets, the rapid growth of the market is also a great opportunity for Xilinx.

4G will be an important growth point in the next five years, and one of the major challenges that LTE technology will face is the conflict between bandwidth and delay. The bandwidth demand of users for LTE is higher than that of current 3G. The bottleneck of LTE technology is the delay, that is, it must be required to complete all the tasks in a fixed time. However, most devices now have to sacrifice time delays to meet bandwidth requirements in the face of bandwidth pressure, and to extend the time in order to increase the number of users. This raises the issue that LTE must complete all processing within a fixed period of time. This means that the demand for FPGAs is even greater. In the 2G era, we did not see too many FPGA design concepts. However, starting from 3G, operators are paying more attention to the performance that FPGAs can provide. Most of the 3G devices use FPGAs to solve the conflict between delay and bandwidth. It is not difficult to find that with the fourth-generation communications technology, there will be a greater demand for FPGAs.

The deployment of domestic TD-SCDMA has been in full swing, and the 4G market has broad prospects, which will affect the operators' choices and decisions. Xilinx launched the 4G plan to promote the continuous development of the communications market.
