In computer architecture, 1-bit integers or other data units are those that are 1 bit (1/8 octet) wide. Also, 1-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers of that size.

Dec 20, 2023 · Japan’s Switch Science released the 1-bit CPU assembly kit last week, boasting that it is “one of the world's top-class low-performance computers.” Despite the mixed messages in its claim to...

Y ou only need one bit to build a functional CPU. It doesn’t make for a particularly useful CPU; you can flip a bit and that’s pretty much it. But it is the simplest CPU you can build and an excellent starting point for figuring out how a CPU works.

Feb 6, 2021 · The Motorola MC14500B 1 is a 1-bit processor introduced in 1976. While a 1-bit processor might seem almost useless, 2 it was marketed as an Industrial Control Unit for applications that made simple decisions based on Boolean logic, for example, air conditioning, motor control, or traffic lights.

The 1-bit ALU circuit diagram consists of several key components, including logic gates, multiplexers, and flip-flops. These components work together to enable the ALU to perform its operations, such as addition, subtraction, AND, OR, and XOR.

The goal of this project is to build a Computer that is compatible with the WDR-1-Bit-Computer, including some peripherals. Software compatibility is the high goal there.

Dec 1, 2016 · Grappling with the design of a 16-bit CPU with a straightforward data path is hard enough. Throw in modern superscalar execution, pipelining, multiple levels of microcode, speculative...

Jun 11, 2021 · While a 1-bit processor might seem almost useless, it was marketed as an Industrial Control Unit for applications that made simple decisions based on Boolean logic, for example, air conditioning, motor control, or traffic lights. Ken Shirriff discusses reverse engineering this classic chip.

Apr 11, 2020 · Updated! Alternative variant by the english version of the Elektor magazine. Original pages of the computer, but also contain many additional modules and extensions as well as demo code.

UE-0.1 is a one-bit single-board computer built with 24 vacuum tubes! The UE-0.1 is a scaled-down version of the UE-1. The full-sized UE-1 fits on a wall and contains 192 vacuum tubes that implement a fully functional arithmetic logic unit (ALU.) Lovett based its design on a 1-bit Motorola MC14500 industrial processor.
