As a support for exercises for the annual lecture course on "Technische Informatik" in the second year computer science curriculum at the University of Karlsruhe a java-visualization to demonstrate the simple execution steps for multiplication and division of binary numbers has been implemented. Input numbers are assumed to have a word length of 8 bits using a fixed point format for either sign-magnitude or two's complement representation of negative numbers. To improve understanding the details also decimal input or output representation has been made available. The start of the demonstration is almost self-explaining: Select the page with any web browser and input the operands!
