How Xilinx XCVU9P Uses SSI Technology to Drive the Highest FPGA Signal Processing

Beyond the components and peripherals, signal processing is one of the core elements to pay attention to in an FPGA. When the signal processing and distribution is inappropriate, the device may not function optimally as it should.

The reverse is the case if the signal processing is operating as it should. In light of this need, Xilinx has provisioned an excellent signal processor in the Xilinx XCVU9P. It is an FPGA family that uses the SSI technology to drive the highest signal processing.

In this article, we point out how the Xilinx XCVU9P is able to achieve that and what the SSI technology is all about.

A Word About Virtex UltraScale Devices

Xilinx XCVU9P is a Virtex UltraScale device. Like the others, it is hinged on the robust UltraScale architecture, which is one of the best architectures to use for FPGA design.

The Virtex UltraScale architecture pushes Field Programmable Gate Arrays (FPGAs) to have one of the best performances. In addition to this, it provides for the optimization of the devices for high-end and compute intensive applications.

One other notable feature of Virtex UltraScale devices is the multiple power reductions innovations. This includes the use of the SSI technology.

Xilinx XCVU9P’s Use of the SSI Technology: What You Need to Know

The SSI technology means Stacked Silicon Interconnect technology. It is a dedicated technology that enables the delivery of the highest satisfaction of FPGA demands, especially as they pertain to the use of the Xilinx XCVU9P device.

The Stacked Silicon Interconnect (SSI) technology also sees to the interconnection of FPGAs and related devices. According to the SSI technology whitepaper, some challenges have been existing with regards to FPGA interconnection.

One of those challenges is the latency that comes with passing signals between Field Programmable Gate Arrays (FPGAs). This latency goes a long way to reduce the performance of the device, as the time spent could have been used to complete the device’s configuration.

Another challenge is the insufficiency of the Input/Output (I/O) pins. The reduction of the pin count means that the device wouldn’t be easily configured, especially for the complex network signals.

To resolve this, the SSI technology in the Xilinx XCVU9P has been delegated to do the following:

Creation of FPGA Die Slices

The SSI technology enables the creation of similar designs for the Xilinx XCVU9P Field Programmable Gate Array (FPGA). It is evident in the use of FPGA die slices to improve the functions of the device.

Typically, the combination starts from the proprietary ASMBL architecture that includes the core building blocks of an FPGA. It also helps in the creation of an assortment of devices that match both the market and user requirements.

Wide Range of Applications

The Xilinx XCVU9P is also ideal for a wide range of applications, especially the ones that involve high computations.

Examples of the use cases/applications are:

  • Radar
  • Wired communications
  • Network acceleration
  • 5G baseband
  • Machine Learning (ML) and Artificial Intelligence (AI)


From the review we wrote in this article, you now understand how the SSI technology plays a role towards Xilinx XCVU9P’s improved performance.

In addition to the stated use cases, you can also use the device for other applications, such as emulation, prototyping and test & measurement.
