hamster Posted October 22, 2015 Share Posted October 22, 2015 I've got my 1080i real-time fractal design running on the Genesys2 board, and the source checked in at https://github.com/hamsternz/FPGA_Mandelbrot - I spent last night getting rid of the 8-bit colour look, using the HDMI's 24 bit range.It uses about 100k flip-flops, 150k LUTs and 640 DSP slices, so uses a large chunk of the FPGA. If anybody is after a reference point, the Kintex-7 FPGA on the Genesys2 added 0.670ns slack to the 225MHz design that just meets timing on he Artix-7. But I can't make can't make use of the extra speed as the calculations run at a multiple of the pixel clock. The logic was also fast enough that I could implement 20% of the multipliers using LUTs - allowing me to get to 255 iterations in real time.

hamster Posted November 22, 2015 Author Share Posted November 22, 2015 I've updated this project... As well as buttons it can use PmodENC (rotary encoder) to zoom, and an analog joystick on a PmodAD1 for pan. Link to comment Share on other sites More sharing options...
