Therefore, you will also need a register entity, a 2x1 mux entity, a subtractor entity, and a comparator entity. > I am planning to implement 1 ALU unit, 1 Branch unit, 1 SET unit, and 1 >LDST unit. The implementation is simple in Verilog –just add a if-else statement to specify that when RST = 0, reset on the nextclock rising edge. Verilog Code For Single Cycle Processor. Please let me know if your able to do so. xdc constraints files. Here, the pipeline segments (Seg #1 through Seg #3) are arranged vertically, so the data can flow from the input at the top left downward to the output of the pipeline (after Segment 3).
