CPU 4 Background. Weird CPU My first CPU (https://hackaday.io/project/12879-weird-cpu) was an 8 bit TTA (Transport Triggered Architecture). It has a front panel and sits happily on my shelf chasing LEDs in circles (such is the life of a simple CPU):...

Schön Core
Details from Schön Core
This series of CPU's is based on the Scott Architecture ( from the book 'But How Do It Know' by J. C. Scott ) and modified by me.There are 4 types of CPU's I've designed so far;Schön Core Lite which is an 8 bit computer that is quite light on resources...

Super Simple CPU - Logisim
Details from Super Simple CPU - Logisim
Just like other projects of this type, I think this is a great simple starting point to understand a CPU. It is one step simpler than the CHUMP design for example. Though not really practical for any real use, but shows the basic parts. If this were...

Microcode-less TTL CPU
Details from Microcode-less TTL CPU
Architecture Wikipedia article: Transport Triggered Architecture Since the CPU doesn't utilize microcode (I don't have an EPROM burner so one of the goals was to create the CPU without EPROM chips), it can do only one simple thing: move data during...

Generic 8-bit Processors Prototype (G8PP)
Details from Generic 8-bit Processors Prototype (G8PP)
Many 8-bit processors and some 16-bit processors from 1970's and 1980's are packaged as 40 or 48-pin DIP which is easy to prototype, processors such as Z80, 6800, 6809, 8080, 8085, 1802, 6502 and some 16-bit processors with 8-bit bus such as 68008...

FPGA computer
Details from FPGA computer
New Planned Specs New architecture that leans more toward RISC, but has many similarities to x86 architecture. 64-bit 4 general purpose registers 2 pointer registers should be ABSURDLY FAST (for an FPGA) Still in the works.... Old Specs for early N016...

The ZStation: an 8 bit game console
Details from The ZStation: an 8 bit game console
System Architecture: This device will operate mainly on the Z80, with an ATMEGA1284 microcontroller as a coprocessor to handle graphics, audio, and IO. Both chips are connected through an IO bus where the CPU uploads data to the MCU to do it's thing....

The simplest 4-bit RISC CPU
Details from The simplest 4-bit RISC CPU
* This project is sponsored by PCBway, full feature custom PCB prototype service. https://www.pcbway.com/There are many prior examples of 4-bit CPU projects. For example, a 4-bit CPU (TD4 once again) by Fedor Gruzdev https://hackaday.io/project/161708-4-bit-cpu-td4-once-again...

Zinnia (MCPU5)
Details from Zinnia (MCPU5)
An 8 bit RISC CPU for TinyTapeout. Tinytapeout combines 500 designs on a single IC to be taped out with the Open MPW-7. This offers the opportunity to actually get a design made on a real IC, but also comes with some constraints: Maximum allowed area...

PROCESSOR SPECIFICATIONS 32 bit design8 registers, including 4 general purpose registersup to 4 GB of RAM without bankingWritten in VHDL for easy FPGA implementationVBCC C compiler seems to work! I designed it to be simple, effective, and useful. ...

Holy Nonads! A Nine-Bit CPU!
Details from Holy Nonads! A Nine-Bit CPU!
This project is implemented on a (somewhat dated) Xilinx Artix-7 FPGA board, the BASYS 3 development board. The specs for this CPU of mine are decidedly retro - 100MHz clock ( 12.5MHZ instruction execution frequency), 9 bit address and data bus. ...

ALU in DCTL technology
Details from ALU in DCTL technology
Now it is much too hot in the attic to work on my RISC Relay CPU, thinking starts about a next project. So I designed an ALU (wikipedia: ALU) in DCTL, that might be used in a next project. The ALU was simulated in the Falstad simulator, that...

CBS6000 Computer
Details from CBS6000 Computer
The CBS6000 is a 6502-based computer I built back in 2014. Back then I took great interest in retro computing especially Commodore 64 computers. Some of these computers did not work, so they would be repaired or scrapped for parts. I had a spare 6510...

OPC-5 - a CPU for FPGA, in one page
Details from OPC-5 - a CPU for FPGA, in one page
What kind of CPU can you describe in one page of code? Will it be usable? (You bet! In fact we've found it to be a pleasure to program.)Having previously built a short series of one-page 8 bit CPUs for CPLD, we wanted more space, and decided to target...
