As the name suggest, this category of computing devices does not have any instruction set. At a first glance, this may seem impossible and you may think over how a minimum of two distinct symbols are needed to represent an information (in connection to binary numbers).

Zero instruction set computer (ZISC) is a computer architecture based on two fundamental ideas:

  • Pattern matching
  • Absence of micro instructions
