Part two of my series on designing a simple CPU is now available:

Today's exercise is mapping the instructions to the 256 available opcodes.

#Hardware #ProcessorDesign

The last couple of weeks, I've been playing with the idea of designing a CPU, at the gate level. I've finally bitten the bullet and started writing up some of what I've been doing. So, there's a blog post on my long-dormant website at https://carfax.org.uk/posts/trivial-processor-part-1/ that starts out with trying to pick out an instruction set.

#Hardware #ProcessorDesign

We're seeing some great progress on the hardware (FPGA) implementation of the Ember CPU! The Verilog simulation of the CPU on a Cyclone V FPGA in QuestaSim can now process LDI (Load Immediate) and MOV instructions. Next step, the ALU!

Switching topics to I/O and game controller support, this week we look briefly at the PIA for Project Ember

Boards look great! Starting the slow bring up with just the CPU, RAM, and ROM...and, of course, clock circuit and logic analyzer...

Next, we'll explore the details of the GPU and the initial design of the first simple text mode display!

Moving on to the system design, this is an overview of the remaining parts we need to design in order to create a working system capable of playing 80s and 90s-era homebrew video games.
