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 ...

Editor’s Note: In this series of articles based on his book – Design Recipes for FPGAs – Peter Wilson provides a basic quick overview of VHDL (VHSIC hardware description language) followed by ...

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 ...
