The Xilinx ZYNQ chip has a hard macro ARM cortex 9 running at 800 mhz or higher. Most fpga designs end up synthesizing to a much, much lower frequency, like maybe 100mhz. The rule of thumb from Xilinx was that you need about 10 pipelines of data in an algorithm before it becomes worth running in the FPGA versus running in the processor. With intel processors running in multi gigahertz ranges, that might be 40 or 50 pipes deep before its better to run on an FPGA. > On Wed, May 3, 2017 at 10:13 PM, Tom Metro <[email protected]> > wrote: >> I think that is saying free developer access...so interesting >> opportunity if one wanted to learn VHDL. Why would you curse someone with the pain and suffering of VHDL? Does Amazon's service come with High Level Synthesis tools? You could write your algorithm in c and then run it as software and run it in an fpga and do a side by side comparison to see which is faster. _______________________________________________ Hardwarehacking mailing list [email protected] http://lists.blu.org/mailman/listinfo/hardwarehacking
