We discovered this medieval castle on a Philips integrated circuit labeled V7191 that was made around 1990. This is the same chip that sports a mother and baby owl nesting on a tree branch and tucked away inside the interior circuitry of the chip. Martin Hummel, an ASIC design engineer for AB-Semicon in the United Kingdom, informs us that this chip is a Video Multistandard Decoder.
Birger Schwarz points out that this castle strongly resembles the Hamburger Stadtwappen, a castle that is part of the official arms of the city of Hamburg, Germany. Birger also points out that Philips has a chip fabrication site in Hamburg, which probably means the castle icon is a signature for that plant.
