One enterprising individual has built his own 8-bit CPU from scratch, on solderless breadboards -- and learned to program it, too.

Die area is 150 x 170 µm using the Skywater 130nm node. Limited to 8 digital input and 8 digital output signals. A RISC 8-bit custom CPU. 7 instructions, 10 registers. Register x0 is always 0, ...

While it might seem odd to create a new 8-bit CPU when you can get bigger CPUs for pennies, you have to consider that 8-bit machines are more than enough for many jobs, and if you can squeeze one ...

It might look like a random pile of wires to some, but it is far from random: [Paulo Constantino] built this 8-bit CPU himself from scratch. He built his remarkable creation using wires and 74HC sh… ...

I have completed the design of an 8-bit primitive microprocessor, a project I have been working on for a long time, inspired by the book Introduction to Logic Circuits & Logic Design with VHDL by ...

It was programmed to run an exponential averaging program. A paper on the same circuit was also published at ISSCC in February 2014 and the circuit is a development of an 8-bit organic microprocessor ...

With Moore's law approaching its physical limits, low-temperature computing technology is ushering in unprecedented development opportunities. Rapid single-flux-quantum (RSFQ) circuit technology is ...

The CPU also includes two 8-bit address registers, a 16-bit stack pointer, and a 15-bit program counter, which the CPU can access as upper and lower 8-bit registers. Advertisement. The COP8 executes ...
