From Ben Eater. Parity checking is a basic technique for detecting errors in data transmission. This video explains how it works and walks through building hardware to compute and check parity. The hardware is based on my previous video: https://youtu.be/eq5YpKHXJDM Code from this video: https://github.com/beneater/error-detection-videos Hardware used in this video (affiliate links): 4x Breadboards: http://amzn.to/2uXgIVO…

From Ben Eater. In this video we program the microcode of the 8-bit breadboard computer so that it supports two conditional jump instructions: JC (jump carry) and JZ (jump zero). We also test out these new instructions and write several programs using them.

From Ben Eater. The 8-bit breadboard computer is certainly limited. But is it capable enough to even be a computer? In this video we explore how Turing Machines and the Lambda Calculus defined the whole class of “computable problems.” And we talk about the relatively minor change needed to make the 8-bit breadboard computer Turing…

From Ben Eater. Everyone seems to want net neutrality, yet it remains a contentious issue. Is pure evil the only reason anyone would oppose it, or is it a bit more nuanced?

From Ben Eater. In this video, we’ll add several new machine language instructions to our CPU: STA (store A), LDI (load immediate), and JMP (jump). Then we’ll write a program that uses those instructions and walk through the execution.

From Ben Eater. See https://eater.net/bbcpu8-control-logic for more. In this video we use two EEPROMs to translate the instruction cycle ring counter and the contents of the instruction register to the correct control signals for each microinstruction. At the end of the video, we run the first full program! Support me on Patreon: https://www.patreon.com/beneater https://www.eater.net https://twitter.com/ben_eater…

From Ben Eater. In this video, we talk about the difference between instructions and microinstructions. Then we build a ring counter to keep track of where we are in the instruction cycle. Finally, we hook up a quick-and-dirty implementation of the fetch cycle to demonstrate instruction fetching. See https://eater.net/bbcpu8-control-logic for more. Support me on Patreon:…

From Ben Eater. In this video, we walk through writing a program—using a machine language we get to make up! Then we walk through exactly what the control logic will need to do in order to execute the program. See https://eater.net/bbcpu8-control-logic for more.

From Ben Eater. In this video, we’ll first build a simple 8-bit register to store the contents of the computer’s output. Then we put everything we’ve built so far together. Everything is tied together through the common bus and common clock signal.
