I read the article co-authored between ImpleC and PICO in FPGAjournal.
The article says that the fixed-point version of the mandelbrot example is
available on your website. Can you tell me where?

Thanks

The Mandelbrot example is a standard application sample provided with the CoDeveloper installation. You can check the Download Zone for links to the current installers.

This particular example has been compiled to two different Virtex-4 platforms, the Pico EP-12 LO (based on a Virtex-4 LX FPGA) and the Xilinx ML403 board (based on a Virtex-4 FX). A forthcoming article in the Xilinx Embedded Magazine describes this and other similar examples used for PowerPC performance benchmarking.
