Arithmetic-logic-Unit

• Implementation of ALU unit in microprocessor and other digital circuits using VHDL.
• Designs requirements are
  • 8-bit adder/subtractor based on ripple carry adder.
  • 16-bit carry look-ahead adder with minimum gate delay that adds A0-15 to B0-15 then produces S0-15 and C16 using structural modelling.
  • 8-bit array(regular) multiplication.
  • 8-bit sequential multiplication.
  • Radix-2 Booth’s multiplier for multiplying 8-bit operands.
  • Non-restoring division circuit.
  • 8-bit ALU with inputs (A , B) and Z as output which is capable of carrying out 8 operations(ADD,SUB,MULT,DIV,OR,AND,Not,XOR).
  • Ripple counter with d and t flip flops.
• You can find circuits designs in Circuit-Designs directory.
