Accolade Technology uses Xilinx FPGAs exclusively for all products. As a result, we keenly track the latest FPGA technology trends with an eye to how we can utilize new capabilities to help our customers. In the summer of 2019, Xilinx introduced a new capability in their high-end FPGAs such as the UltraScale+ called HBM or High Bandwidth Memory. For a detailed look at HBM watch this video: https://www.xilinx.com/video/fpga/high-bandwidth-memory.html
In short HBM takes advantage of silicon stacking technologies to place the FPGA and the DRAM beside each other in the same package. The result is a co-packaged DRAM structure capable of multi-terabit per second bandwidth. This provides system designers with a significant step function improvement in bandwidth, compared to other memory technologies.
The last statement above is what gets our FPGA designers excited. With this new ultra-high-speed memory access any Accolade feature that relies on table lookup or table access can get orders of magnitude improvement in terms of speed. The best example is any of our flow classification related features such as flow shunting which relies on a table to track and monitor 10s of millions of flows. With HBM flow shunting suddenly gets a massive boost in performance.
