What Datapath Elements Do We need?

• Two registers to hold LOW, HIGH value

  • Use LPM_DFF or write VHDL model (reg6.vhd)

• Need a 6-bit counter to cycle address lines of RAM

  • LPM_COUNTER
  • Counter needs to be loaded with LOW value when we start to zero the RAM

• Need a Comparator to compare Counter value and HIGH value to see if we are finished

• Need the RAM (use LPM_RAM_DQ)

• Muxes (LPM_MUX or VHDL)
