Even More Phenomenal Cosmic DSP Prototyping Power: ASIC Prototyping Platform harnesses four Kintex UltraScale KU115 FPGAs

Need several million ASIC-gate equivalents for your FPGA prototyping? One way to do that is to use the world’s largest FPGA, the Xilinx Virtex UltraScale VU440—with 4.433M logic cells (equivalent to roughly 44M ASIC gates)—the way that S2C did with its recent introduction of the Single VU440 Prodigy Logic Module. (See “Phenomenal Cosmic Prototyping Power, Itty Bitty Package: The new S2C Single VU440 Prodigy Logic Module.”) Another approach, also taken by S2C on its brand new Quad Kintex UltraScale Prodigy FPGA Prototyping Logic Module: combine four Xilinx Kintex UltraScale KU115 FPGAs on one board with an aggregate capacity of 4.644M logic cells, equivalent to roughly 46.4M ASIC gates. But ASIC prototyping logic gates are not really the story here. This story’s about DSP.

A lot of DSP.

After all, we’re talking about the Xilinx Kintex UltraScale KU115 FPGA.

Here’s a block diagram of this new board:

And here’s a spec comparison of S2C’s two UltraScale-based FPGA Prodigy Prototyping Modules:

Single VU440 Prodigy Logic Module

Quad Kintex UltraScale Prodigy Logic Module

Logic Cells

4.433M

4.644M

Block RAM (Mbits)

88.6

303.6M

DSP Slices

2880

22080

I/Os

A few things jump out at you from this table. Four Kintex UltraScale KU115 FPGAs give you more resources than one Xilinx Virtex UltraScale VU440 FPGA. You get a lot more block RAM and nearly 10x the number of DSP slices with the Quad Kintex UltraScale prototyping board. You don’t get any more I/Os however because that’s a board/connector limitation. Both boards are part of the company’s Prodigy Complete Prototyping Platform.

Put a few of these bad boys in your S2C Cloud Cube if your design needs phenomenal, cosmic DSP capabilities.
