Wireless applications: OS consideration for Zynq All Programmable SoCs: Page 5 of 5

April 15, 2015 //By Yuan Gu, Xilinx
With the explosive increase in wireless data throughput, there is tremendous pressure on improving digital signaling processing technology and radio equipment. Currently, the focus is on 4G LTE.
The migration from discrete multi-chip solutions to a single-chip integrated solution on the Zynq platform is fairly straightforward. Xilinx provides a smooth migration path to Zynq devices with comprehensive hardware and software solutions. This includes a DSP (digital signal processing) IP library for the DUC, DDC, CFR and DPD. Additionally, multiple OS solutions are supported including device drivers, boot loaders, BSP template and common tools. With a successful migration onto the Zynq platform, this solution can significantly increase the system performance, save total power consumption and lower the BOM cost.

Throughout the document, we discuss key considerations of operating system selection for wireless applications, the implementation architecture and considerations for those (AMP versus SMP), and the direct application of those on a Xilinx Zynq-7000 All Programmable SoC device. In conclusion, these advanced devices from Xilinx enable infrastructure equipment designers with improved performance, increased system integration, lower total BOM cost and lower total power, high reliability and improved time to market while also enabling full programmability of both software and hardware. Designers can now not only develop equipment faster, but also continue to provide updates to the field long after the equipment has been deployed, removing the risk involved with devices such as ASSPs and ASICs.
