I have once again massively compressed my decoder. this is so fucking epic.

does anyone have info on going through TSA without real id? i have to do it in 2 days. TSA officially recognizes this procedure and says so on their site. i've spoken to people who have done this after may this year, and got through. just wondering if there are tips on what to bring and what to say

i realized that the ROM would grow rapidly as control lines and instructions were added, so i instead opted to have separate ROMs for domain-specific lines, like ALU logic. it resulted in massive EPS and space savings

im starting to wonder if im insane. i have the ret operation set the returning sp to the outer bp, so not popping is okay? i just don't have a way to do pointer arithmetic inline. it has to be done with so many instructions lol. in normal-people assembly i'm pretty sure it's like "mov [ebp-4], 3"
![screenshot of an untested function that is fed 7 arguments, and attempts to return the value contained in argument 6 using pointer arithmetic relative to the base pointer. i have no inline arithmetic for the base pointer, so this is probably the simplest way for now. i wonder if i'm going insane or if this actually has to be done this way. it's hard for me to conceptualize the difference between constant/static and runtime when it comes to assembly, cause it's just so different from system-level languages. i sat there staring at the screen for many minutes before i realized i had to add the m[reg] capability for load. and i can't do arithmetic on that either since it's "runtime". it's hard to explain because i haven't wrapped my head around it.](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:umf7io4mm4l2afqbdialeqze/bafkreie4pewcqtvcv5itheunno62bdbkuvdxssdgeydrwedffytja4d2pa@jpeg)

i'm working on a calling convention. i think it's really cool that customasm lets me statically determine the return address (which MUST be pushed first) by checking the size of the instructions for pushing the arguments. the alternative would be using a dedicated register, which sucks.

i actually have no idea how ptr[] and mem[] is used in normal-people assembly. but i made the syntax more explicit to make it easier to learn and remember my own ISA as i look at it

Here's my adder as an SVG (left), and a whole CPU someone else made (right). I made the graph with graphviz and VCBTool. It's pretty cool.

the syntax is getting more interesting. i'm using pattern-matched "types" with subruledef for the shit like ptr[x] and mem[x]. i have no idea if this is what it's supposed to look like for nasm/gas/etc. this is fun though. on the bottom are "global variables" i guess you could say, but stack better.

decided to use online blueprints, as reinventing the wheel is not my intention here. i want to push boundaries. (i did make the adder on the bottom-left). what you see here though is far from pushing anything at all. but i am learning.

here was the unfinished 8-bit "cpu" i designed in the past. It only supported two instructions. load into register, and movl. but it runs the program just fine (unless the timing is too fast)

i made some counters using (stateful) latch inks. my old 2-stride design was pretty ugly (2nd image)
