The project is a 4-bit ALU in VHDL with a total of 16 operations which includes various arithmetic, logical and data calculations performed by coding the ALU in VHDL code. The project is a 4-bit ALU ...

In this paper VHDL implementation of 8-bit Arithmetic Logic Unit (ALU) is presented. The design was implemented using VHDL Xilinx Synthesis tool ISE 13.1 and targeted for Spartan device. ALU was ...

In today’s Integrated Circuits (ICs), Built-In Self-Test (BIST) is becoming increasingly important as designs become more complicated. BIST is a design technique that allows a circuit to test itself ...

As can be seen from the VHDL, we have defined a specific 16 bit bus inthis example, and while this is generally fine for processor design with afixed architecture, sometimes it is useful to have a ...
