Someone evidently forgot to tell [Notbookies], for he has made a complete 8-bit ALU using only 4011B quad NAND gates on a set of breadboards, and in doing so has created a minor masterpiece with ...

It’s 8-bit output can be used as a random sequencer for DIY CMOS synths. This pattern generator is suited to to be used in combination with a 4051 8-channel analog multiplexer.

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.
