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.

An Arithmetic and Logic Unit (ALU) is a digital circuit that performs arithmetic and logic operations. In this work, the demand is to design an 8-bit ALU and perform analysis at gate and layout ...

Hovey's 8-bit ALU (arithmetic logic unit) is constructed completely out of transistor-transistor logic (TTL), as are the registers. The microinstructions (the op code, the ISA) that actually ...

We mean building something closer to a fully-programmable 8-bit computer from the ground up, like this one from [Federico] based on 74LS logic chips ... a capable ALU, four seven-segment LEDs ...

When we are introduced to the internals of a microprocessor, it is most likely that we will be shown something like one of the first generation of 8-bit CPUs ... and logic unit (ALU), and an ...
