Agenda on Bits & pieces - Sven Wehrend

USB, SPI, I²C, Sata - all these interfaces is common that they are serial interfaces.

What I have learned about religions and spirituality over the last years and decades boils down to one simple statement: Religion is about right and wrong and old, outdated dogmas, while spirituality simply says "It is how it is".

How does a CPU work 2 - Table of contents From Combinatorial to Sequential Logic - Introduction Introduction to Sequential Logic We get from purely conmbinatorial logic circuits wihout any form of memeory to sequential logic circuits with some type of mem…

Sequential Logic Complementary to Combinatorial logic, sequential logic contains some type of memory, making the behaviour state-dependent.

Ein analoger modularer Synthesizer war schon immer mein Traum, letzte Woche habe ich mir diesen Traum erfüllt und den Pocket Operator Modular 400 von der schwedischen Firma Teenage Engineering bestellt.

Today I want to introduce a solution for a usability-problem I had in Odoo recently.

As the blog grow bigger and after the move to hugo, I noticed a gap in the workflow,since a blog and its content itself are different entities, I wanted to handle them as such, that led me to a cleanup of the original source code for blog, where I moved t…

This course about digital logic is splitted into two big chunks: Combinatorial circuits (without memory elements) Sequential circuits (with memory elements) While combinatorial circuits consists of boolean gates interconnected without feedback function, s…

Since one week my blog is build on the static-site-generator Hugo.

Digital design meets computer architecture RISC vs CISC and The RISC-V architecture Existing processor types can be classified by their instruction type set: Reduced instruction set computer (RISC), Complex instruction set computer (CISC) and hybrid forms.

Memory Organization In this blog post the author will introduce the different types of semiconductor memory.

Clocks, Flipflops and registers In this blog post the author will introduce multiple elements needed at a later stage.

The ALU, the swiss knife of every cpu Today the author wants to introduce an important part of every cpu: The arithmetic logic unit (ALU), we already know about some functions presented in the blog posts before.

Extending the binary system While in the previous blog post about addition, the binary numbers had only one interpretation, we extend the system here to include negative (integer) numbers.

The Binary System All computer we act with on a daily base do not know about the decimal system we are using, based on the ten digits at our hands.

== XOR As there are a lot of important applications for the exclusive-or (XOR) operation it is dedicated an own blog post.

After this chapter you will know all the basics around electricity and simple circuits utilizing ohmic load… Prequel Introduction to electronics While I was about to write the implementation part of the boolean algebra post, the basic logic gates, the wri…

Boolean Algebra and Basic Logic Gates We are starting (the journey) with three very basic logic functions (or operations), which despite their simplicity already are valid instructions of a regular CPU: NOT, AND and OR Logical functions - also called oper…

== How does a CPU work – Table of Contents Introduction and Overview Introduction and Overview Each topic in this course is divided into two parts: one focusing on the mathematical side of digital logic— ideally independent of implementation details— and…

While drafting a blog post, part of a series of posts intended to be published in the future, I discovered a lack of my tooling in Nikola.

A simple static blog meant for writing about topics like electronics & computation and - maybe - philosophy.

I picked up Nikola some months ago as I was searching for a simple static-site-generator to setup a blog with minimal effort.
