Webb17 juni 2015 · Therefore, if you have a circulant matrix, C, and you want to solve a system, C x = b, you can simply write, F D F H x = b → D F H x = F H b. Now count the fft's. We need one to determine the diagonal matrix D (as you stated in your comment), another to determine F H b, and finally one inverse fft to recover x from F H x. – Chester.

WebbIn this paper we show a real-world example where we created a common network function, RSS, using both traditional RTL/Verilog tools and then using high-level synthesis (HLS) on the same hardware. What we found was surprising: the HLS approach actually used fewer FPGA gates and memory. There is a reason. Read on for details.
