4-bit computing - Wikipedia
4-bit computing is the use of computer architectures in which integers and other data units are 4 bits wide. 4-bit central processing unit (CPU) and arithmetic logic unit (ALU) architectures are those that are based on registers or data buses of that size.

2019年1月10日 · What we are going to do is design a simple 4-bit computer at the primitive logic gate and flip-flop level and then implement it in the technology of our
A 4-bit Computer - Frank DeCaire
2024年2月4日 · I recently (like a few months ago) stumbled onto an article about the Nibbler. It’s a 4-bit computer built out of discrete logic. There is no microprocessor, so this is lower level than slapping together a minimal system with a Z-80. Here’s the original article if you want to see what I’m attempting: Nibbler 4-bit CPU.
Building a 4-Bit Computer: The Instruction Set - EEWeb
2019年8月5日 · As you may recall, one of my background hobby projects is to build a 4-bit HRRG Computer. In the fullness of time, this will be realized as a collection of wall-mounted, glass-fronted wooden cabinets, each containing part of the computer.

[2410.15526] SDP4Bit: Toward 4-bit Communication Quantization …
2024年10月20日 · Driven by this limitation, we propose SDP4Bit (Toward 4Bit Communication Quantization in Sharded Data Parallelism for LLM Training), which effectively reduces the communication of weights and gradients to nearly 4 bits via two novel techniques: quantization on weight differences, and two-level gradient smooth quantization.
