GSI offers free IP to enable 7.2Gbytes/sec transfers in each direction between its SigmaQuad-IIIe SRAM and UltraScale FPGAs

Got memory transfer-rate problems? Need more memory speed? GSI Technology may have an antidote for your problem in its SigmaQuad-IIIe SRAM, which is capable of transferring 7.2Gbytes/sec in both the read and write directions simultaneously when connected to a Xilinx Kintex UltraScale FPGA over separate, 36-bit read/write buses. That’s with an 800MHz clock rate.


How does GSI know this? The company has developed its own eval board to develop the memory controller IP needed to effect this nosebleed transfer rate and that IP is available free to GSI’s customers. (Contact GSI directly for more information.)


Here’s a photo of the GSI Eval Board with a SigmaQuad-IIIe SRAM connected to a Xilinx Kintex UltraScale KU040 FPGA:

For more information, see this GSI brochure titled “Leading-Edge Memory Solutions for UltraScale & UltraScale+ FPGAs.” You might note from the brochure that GSI is already experimenting with Xilinx Kintex UltraScale+ FPGAs and their SigmaQuad-IVe SRAMs. Unsurprisingly, that combination goes even faster. More details when they’re available.
