40-fps 16-bpp platform game on a Cortex M0+ board
Details from 40-fps 16-bpp platform game on a Cortex M0+ board
Introduction I wanted to see how far I could push the Cortex M0+ of the Arduino Zero. I think it is a balanced microcontroller: not too limited like an AVR, not too fancy, like a Cortex M4 (which has enough computing power even to run Doom). I wanted...

TMS0800 FPGA implementation in VHDL
Details from TMS0800 FPGA implementation in VHDL
There are plenty of great implementations of different and historically important CPUs available on various FPGA-based platforms, but to my knowledge very few trying to implement calculator CPUs. Old calculators where one of the first examples of "microcontrollers"...

Pineapple ONE
Details from Pineapple ONE
Almost every electronics device uses some kind of a microcontroller nowadays. The thing is, that these chips can be very complicated, and even though you can buy them very inexpensively (like Arduino for example), I've still wanted to take a deeper...

Custom parallel processors in Verilog/FPGA
Details from Custom parallel processors in Verilog/FPGA
Nakano, K., et.al.(refs below) describe two versions of a small stack machine suitable for implementation on an FPGA and they give the Verilog source code on their web site. The design was ported to the DE2 board and extended to have a richer set of...

NSX-64
Details from NSX-64
Nintendo 64 controller is read by NicoHood's Nintendo library and the buttons are converted to MSX equivalents according to the table below. Analog stick is mapped to MSX controllers using a paddle emulation function that responds to an interrupt that...

This is a medium-high-level discussion about general computer program organisation. For lower-level CPU design tricks, dos and don'ts, please check it out: #PDP - Processor Design Principles :-) The way we are used to program computers is a long evolution,...

CP/M on a minimal Z80 Computer
Details from CP/M on a minimal Z80 Computer
The Z80 CPU is clocked by a 4 MHz TTL oscillator module. Next to the CPU, there is a 128 Kilobyte static RAM chip, of which the Z80 uses 64 Kilobytes, the maximum it can address. The RAM is battery buffered, so it can remanently store the programs...

Retro 68000 CPU in an FPGA
Details from Retro 68000 CPU in an FPGA
I've wanted to build a 68000 system for a long time. I built some commercial systems back in the 1980's based on the 68000 and really like the CPU. There's a few 68000 builds on YouTube. The best documented 68000 build is Jeff Tranter's build...

Bad Apple!! color VFD ver.
Details from Bad Apple!! color VFD ver.
The VFD module is a 20x8 matrix of pairs of blue and red subpixels. I treat the display as being 16 pixels high and divide the blue and red subpixels between even and odd lines of video, which gives a bit more detail than you'd normally get from an...

V-Tech Genius Leader / PreComputer Hacking
Details from V-Tech Genius Leader / PreComputer Hacking
The goal of this project is to create a set of hardware and software tools to "hack" the 1000/2000/4000 and 6000 series of VTech 8-bit learning computers ("PreComputer"). Current status: The hardware is well understood: Z80 CPU, HD44780 LCD controller,...
