@Adam Fabio created this analog gauge to show your computer’s CPU utilization:Analog CPU GaugeThe goal of this project was to build an analog gauge to display computer CPU utilization. I’ve always been fond of classic analog gauges. Most CPU Gauges are...
I am fascinated by the idea of building a computer all by myself from elementary parts such as transistors, diodes etc. It seems to be a very complex task, but after seeng other people doing it and accomplishing it, now, perhaps I could also do such...
Have you ever made a processor? I did. Took me just 12 microchips and a clock generator. The processor can execute several commands, and programs can be written for it. The program code and input data are entered using micro switches, and the state of...
Natively, i. e. without external devices or coprocessors, the CPU is able to work with two data formats: 8-bit bytes, 16-bit (or two-byte) words. Data bitness can be extended by using specific arithmetic instructions, that take carry flag into account....
What is CPU?The Central Processing Unit (CPU), the main chip of your computer, phone, television, etc., is in charge of sending instructions to the motherboard's various electronic components. The CPU, also known as the "brain" of the computer, is the...
Memory is an array of cells, each of which holds an 8-bit byte, so terms “byte” and “cell” can be used interchangeably. Each byte can be accessed by its unique 16-bit index, which is called “memory address”,...
6809 ON STEROIDS Almost 40 years ago a home computer came onto the scene that appeared to be just another color game computer that the kids could hook up to the TV. The Radio Shack TRS-80 Color Computer affectionately known as the CoCo was...
That was the most expensive CPU, motherboard, memory setup the lion kingdom ever got. Getting a speed boost over what was $400 in 2010 took a lot more money than it did, but hopefully will last another 8 years. The #1 trap for young players: The...
When it comes to homebrew computer designs, nothing beats the classic microprocessors from 1970s and 1980s. SDC is an idea of a computer bringing together old and new technologies. The SDC consists of some real, classic CPU and a modern microcontrollers...
Recently, obtained a copy of Retro Gamer Annual which gives full history and specifications to several older 8-bit consoles.Though working on building two machines, constructing a "test game" for the system (maybe an indie version of Super Mario...)...
Addressing is a way for CPU to locate operands used in instruction. Addressing can be explicit or implicit. If an operand is encoded in instruction as a certain bit fields, then it’s an explicit addressing. The CPU has 5 explicit addressing modes: register...
I figured it will take 37 different parts to build one memory cell (complete with three-state output), and one 16 bit register will require up to 600 parts to solder, and I see it will be a hell of work and time to solder it together and make it work...
From the Hackaday blog:Ice, Ice, Radio Uses FPGABuilding a software defined radio (SDR) involves many trades offs. But one of the most fundamental is should you use an FPGA or a CPU to do the processing. Of course, if you are piping data to a PC, the...
(Being a list of projects I'd like to work on some day)C62 - expanding my existing C61 design to add useful amounts of program memory and an interrupt system.C121 - a 12-bit RISC machine with a fully featured ISA.C181 - an 18-bit RISC machine, hopefully...
Some time ago based on arm + uClinux development of a network monitoring system, seeing the project to be done immediately, and finally relieved, so finishing some notes and ideas and we would like to develop some of this model for some discussion, I...
