[TGTTGIT] recently took the plunge and decided to build his own computer using logic chips. He just completed a 4-bit ALU which can compute 18 functions. It took a long time to get the wiring right, ...

Abstract: This paper introduces an innovative, optimized design for a 4-bit ALU architecture, tackling the longstanding carry-out issue in existing architectures. Notably, our proposed design ...

Increment and decrement. They sound like simple functions. But even the simplest functions can get quite complex in a microprocessor design. Ken Shirriff has written up a great blog post about his ...
