Using Fidex IDE, write an assembly code including an interrupt. The interrupt signal should be generated inside the Picoblaze by your program using an IO port. Make the interrupt vector address as xFFF from the configuration. Remember that interrupt enable flag should be set when an interrupt signal comes.
Connect an IO port to the interrupt input and implement your design in Vivado. An example top module and a simulation file is provided outport is connected to interrupt input Show the instruction addresses and stack pointer before and after the interrupt call in Vivado.
Write nested interrupts and implement your design in Vivado. Show that Program Counter PC returns the initial instruction address first callee after returns.
Write nested interrupts and implement your design in Vivado. Observe the consequences and explain the behavior of Picoblaze. Does Program Counter PC return the initial instruction address?
