CPUAs my first CPU design to leave my notebook, I wanted to keep things simple, so I'm using EEPROMs as simple programmable logic devices. Two 64KB devices make up the ALU, and another three decode instructions into 23 control lines. The design is faster...
The CPU:The Pentium III CPU I'm using is similar to the one used in the original XBox, but runs at a higher core clock and has twice as much cache, but at a slower 100MHz bus. The Dingo Console will have eventually have an overclock function called After...
MP-4 is simplest CPU that you can build and run your programs, including conditional branches and a few arithmetic logical operations. As you can see in block diagram, MP-4 is an harvard architecture microcontroller.In this very first version there is...
PARTS It will consist of the following parts: processor in the spirit of the #1 Square Inch TTL CPU a simple ALU (described here)some address registers (described here)at least 256 KByte RAM flash-ROM for booting VGA videoPS/2...
After exploring a few random online shops one day, run across a very interesting development board EFB-REV1.it is a Free RTOS dual-core 32-bit CPU, 520 KB SRAM,4 MB Flash Memory, CPU operating at 240 MHz. EFB-REV1 has inbuild Serial Interface (RS232...
MKHBC-8-R2 - Multipurpose 8-bit Homebrew Microcomputer. Design and Specifications. 1. Architecture of the system. The system is intended as a hobbyist computing/microcontroller expandable platform. The CPU of choice is MOS 6502 compatible microprocessor....
TOM-1 is a TTL-based processor with a small instruction set. The idea came from reading about projects like Gigatron and Ben Eater's 8-bit video series, as well as Verilog CPU implementations like nybbleForth. The design goal is to minimize chip count...

NOTE: COMIX-35 IS NOT MY PROJECT!The COMIX-35 is an open-source clone of the 1980s COMX-35 8-bit home computer. It uses the RCA 1802 microprocessor which is strange and slow but holds the distinction of being the first CMOS microprocessor. The "35" is...
I have made lots of MCU based circuit and gadget, but felt some missing piece of knowledge between logic circuit (TTL) and software programmable circuit, so CPU.This time I found a very nice Japanese book, denoting "how to make CPU by TTL"Its ISBN is...
NOAHCube The cube is designed to be an automation platform. In this case a center piece that can be placed on your desk. It will be the control hub for your home automation but also a development platform for testing automation ideas. The NOAHCube...
I was doing research for a new hobby project. I wanted to build a 68000 system on a bread board with I/O and possible video. As I dug deeper I started shifting towards maybe starting with an 8 bit CPU (6809) and then do the 68000 after. ...
Computer design goals: Architecture: RISC-like – inspired by MIPS, but is quite different. This is Load/Store architecture, meaning that ALU operations are only applied on data in registers, and for using data from memory it should be first loaded to...
See also this YouTube video describing the way the system works: This is my attempt at making a fast 6502-based homebrew computer. The current prototype is stable at 32.768MHz, which I'm happy with as it's in the same ballpark as 6502.org forum...
