Arithmetic Logic Units are combinations of digital logic gates that performs arithmetic and logical operations on binary numbers. For this project, an 8-bit ALU was made entirely of NAND gates only. A ...

Building a CPU out of logic gates is a great way to learn about the inner workings of microprocessors, and we’ve seen several impressive projects in this area. [c0pperdragon] set himself the task of ...

Not content with your new, 1.4-billion-transistor Ivy Bridge processor? Maybe it runs too hot, or lacks the polygon-pushing powers that you require? Well, I've got just the thing for you: How about ...

Did you ever start a project that you felt gained a life of its own? This project by [Paulo Constantino] is an entire CPU named dreamcatcher on breadboards, and is a beautiful jungle of digital. On ...

The term "Bit Slicing" was once dominant in history books as a technique for constructing a processor from processor modules of smaller bit width where each of these components processes one field or ...

Some of the most interesting projects in computing are the "Just for fun," builds that individuals dream up. A year and a half ago, we met the Megaprocessor, a room-scale CPU implementation with each ...

An earlier logic chip used as a building block for CPUs. Bit slice processors used arithmetic logic units (ALUs) that typically came in 4-bit increments, although 1- and 2-bit devices were also made.

RISC is a design philosophy to reduce the complexity of instruction set that in turn reduces the amount of space, cycle time, cost and other parameters taken into account during the implementation of ...

Austin, Texas — As more of its customers seek performance headroom, Freescale Semiconductor Inc. plans to offer compatible versions of its high-end 8-bit and 32-bit processors, including software ...
