If you are limiting yourself to only 16 instructions, which ones should you chose, and how do you manage without the ones that fall by the wayside? In my previous column on our project to build a ...

The registers inside the CPU, the machine code instruction set, and the ways in which the instructions interact with the registers and status flags are all intertwined. As you may recall, one of my ...

In my previous blog, I reintroduced the concept of the Heath Robinson Rube Goldberg (HRRG) 4-bit computer, which has been on my “To Do” list for more years than I care to remember. As we discussed, ...

Deep learning is an inefficient energy hog. It requires massive amounts of data and abundant computational resources, which explodes its electricity consumption. In the last few years, the overall ...

It might be fair to suspect that most people who are considered digital natives have very little to no clue about what is actually going on inside their smartphones, tablets, and computers. To be fair ...

[Michael Gardi] wrote in to let us know about his project: CPS-1: Imagining An Early 70s 4-bit Microcomputer. The CPS-1 was the first Canadian microprocessor-based computer. It was built by ...

A dozen teenagers in military fatigues sit quietly fiddling with small devices in antistatic bags, waiting, like the other kids around them, for further instruction. A teacher murmurs a few sentences ...

Eight bits make up a byte, so four bits are called a nibble. Computer engineers have a funny sense of humor. Ms Tech | Wellcome Collection Deep learning is an inefficient energy hog. It requires ...
