#DWMC16 #Revision #InstructionSet #DIWhy

Another day, another revision of the Instruction Set. Or rather a revision of the OpCode Encoding to add more Addressing modes...

#DWMC16 #InstructionSet #Revision

And here I thought that I had some good ideas with the V0.4 Instruction set. But nooooo...

My mind insisted that I add Addressing Modes to the Instruction set with V0.5.

And I just made V0.4 yesterday...

Stupid Brain...

#DWMC16 #InstructionSet #Revision

With me writing the Control Logic of The Emulator coming close, I decided to do another revision of the instruction set.

#DWMC16 #Revision

Well, I had a change of mind, but not of heart. I'm going to use 74 series TTl logic for the DWMC-16 from now on forward.

#DWMC16

Urgh... The urge to write an assembler is raising...

And the need to write a low level emulator... In Python...

#DWMC16 #DIYMinicomputer #BlockDiagram

It ainted dead yet.

I finished my first version of the DWMC-16s Block Diagram, mostly to count and design all the control signals that I will need to access the various functions of the computer.

#DWMC16 #DIWhy #Design

Well, with the Basic Register Module under my belt, I realised I need more than just that Module...

So I've written down my thoughts on the other Register modules I need.

#DWMC16 #DIWhy #DIYMinicomputer

Just completed a post for the DWMC-16 design, where I take a think on Opcodes for the instruction set. Largely because I was wondering about writing a simple assembler in Python.

We interrupt this broadcast for a few thoughts on interrupts of the DWMC-16.

Got another blog post on my DWMC-16 project, this time another set of revisions and some new ideas.

#DWMC16 #Minicomputer #DIWhy #PleaseSendHelp

I have just finished writing my initial design for the instruction set for my DWMC-16 minicomputer.

There are a lot branching operations... Some of them are rather specialised...

http://warringersworlds.net/2023/08/14/dwmc-16-initial-instruction-set/

Just put down some of my additional contemplations about the ALU, again, and the Flags that I may need for my DWMC-16 minicomputer project.

#DWMC16 #Minicomputer #DIWhy

Got me these two books on computer development on a basic level from 1977 and 2021 to help me with the work on the DWMC-16.

Yes, I could have gotten either as a PDF, but actual dead tree books have a different quality... Especially the old ones.

#DWMC16 #DIWhy #minicomputer #16bit

I might have taken some considerations about memory design, but talking to a few people, I came to the conclusion that there is already some feature creep in my DWMC-16 design. So I decided that I will remove some of those.

#DIWhy #DWMC16

As the first followup on my initial post of the DWMC-16 project, I have done an initial design for an ALU that looks somewhat promising for use.

#DIWhy #16bit #DIYMinicomputer #DWMC16

Well... I have bitten the bullet and written down a blog post about my initial idea for the DWMC-16 project that I am currently thinking about...
