Brutus is the brainchild of the Austrian programmer and mathematician Dr Christian ("Chrilly") Donninger, pictured on the left after his victory over Fritz.

Donninger's program was constructed for Field Programmable Gate Array (FPGA) systems. These are essentially programmable chips which have the advantage is that anything programmed this way will run very much faster than on a general purpose chip like the Pentium or Athlon.

An additional benefit is that due to the parallel sturcture of the code you can add chess knowledge in any quantity without slowing down the search. In regular PC programs each new quantum of knowledge is bought at the price of search speed.
