Who am I?

After a basic education in computer science, I specialized in computer engineering, especially in FPGA designing with
Xilinx ISE, Xilinx Vivado and Altera Quartus-II as well in simulation and verification of such implemented designs.
While studding in the master program, I got involved in giving lectures and labs on hardware design, too.

My first big project was a streaming optimized controller for the Serial-ATA protocol. One major goal of this controller
was to be platform independent in means of FPGA device, FPGA family, FPGA vendor and even tool chain vendor
independability. The second project was a Gigabit-Ethernet stack for UDP/IPv4/IPv6, which had the same goals as before.

My major commitment now focuses on streaming optimized and platform independent hardware modules, which are
provided open source on GitHub, named PoC -Library. A second commitment is my PicoBlaze -Library, an extension to
the PicoBlaze processor written by Ken Chapman. This library provides a System-on-Chip ecosystem for the PicoBlaze.

My Personal Preferences

  • Preference for the editor, default is the WYSIWYG editor. The options are raw, wysiwyg:
    • Set EDITMETHOD = raw

  • Show tool-tip topic info on mouse-over of WikiWord links, on or off:
    • Set LINKTOOLTIPINFO = off

  • More preferences TWiki has system wide preferences settings defined in TWikiPreferences. You can customize preferences settings to your needs: To overload a system setting, (1) do a "raw view" on TWikiPreferences, (2) copy a Set VARIABLE = value bullet, (3) do a "raw edit" of your user profile page, (4) add the bullet to the bullet list above, and (5) customize the value as needed. Make sure the settings render as real bullets (in "raw edit", a bullet requires 3 or 6 spaces before the asterisk).
