This is an system-on-chip implementation for a very small processor (8 bits). It was design for educational purposes. Using this tool, you could explain the instruction cycle, how works a data path or even how to design a new instruction.

  • Von Neumann Architecture, instructions and data in the same memory.
  • 8 general purpose registers.
  • One special register por program counter.
  • Word size and bus 8 bits. Instructions 16 bits.
  • Microprogramed design.

Only version with interrupt:

  • Support for 3 in-out ports, two ports for input, and one port for output.
  • One interrupt for detect changes in one input port.

For more information, read the documentation (for now is only in spansh, I will try traslate it).
