Put your FPCiA vendor's memory to the tEst. Virtex'"-E Distributed RAM Block RAM SRL16 External Interface Up to 1014 Kbits Up to 832 Kbits Yes HSTL I, Ill, IV A sk your vendor about value for money. For example, exactly how much block RAM does your FPGA vendor offer? The Virtex-E family beats the competition by a wide margin, even double. Does your FPGA vendor offer distributed RAM? It's a great resource for designing scratch pad memory and small FIFOs. Xilinx FPGAs offer distributed RAM in addition to block RAM, maximizing your design options. Does your FPGA vendor make shift register implementation easy? Compared to alternative FPGAs, Xilinx can offer up to 16 times the number of shift registers with our Shift Register LUT macro (SRLJ 6). That's a big plus for delay line matching in DSP applications, or for Virtex'"-EM Up to 301 Kbits Up to 1120 Kbits Yes HSTL I, Ill, IV Alternative FPGAs ? ? ? ? multiplier coefficients in wireless, video, and imaging applications. Can your FPGA vendor offer design flexibility with on-board CAM? Or are you locked into a fixed CAM solution7 Virtex-E supports CAM with either block or distributed RAM, with either single or multiple matches in one clock cycle. Does your FPGA vendor offer any HSTL standard for external memory interface? Do they really7 Xilinx offers 3 versions: HSTL I, III, and IV, with applications notes and design support to prove it. If your FPGA vendor seems forgetful when asked about value, maybe it's time to think about using the Virtex-E family. We invite you to tEst our memory, and more.
