I ran a pretty extensive bench test on some hardware i'm trying on a Cortex M7. it's not fast enough for what I need. I've been avoiding going to more powerful smartphone tech like ARM Cortex A7s due to needing an OS to support it. Fortunately I found an A7 i can run bare metal without an OS so I don't need the end users to stomach Linux boot times
STM32MP157D-DK1 eval board[^] <-- The MCU on this eval board is the magic.
GitHub - 4ms/stm32mp1-baremetal: Baremetal framework and example projects for the STM32MP15x Cortex-A7 based MPU[^]
With this gorgeous offering on github. I owe them a keg of beer for this.
Let's talk about my old platform vs my new one
Old: Single core 480 MHz, realtime, 1MB of SRAM. 2MB of Flash
New: Triple core (2 800MHz A cores, and a 209MHz realtime M core), 768KB of SRAM, up to 1GB of DDR3 (we'll probably use 128MB), flash is external, and can be any size we need, or even an sd reader.
I can't wait for the kit to get here so I can try this. I'm beside myself. This opens up a lot of doors.
This is the sauce i needed, right here (well, the first part of the sauce anyway the primary ingredient)

We live in interesting times.
Sometimes I wish I was still closer to the start of my career. It might've taken an entirely different path.

Interesting device.
Only 9 left in stock and 52 week lead time, hope you only need the one.

That's just the dev board. It's fine. I only need one. And there are others. They're just more expensive.

Very nice as I'm just getting back into coding and AArch64 is the platform. Thanks for this. What assembler is this?

I mean, I'm using the GCC ARM Cross compiler. So whatever assembler that uses.

"Fortunately I found an A7 i can run bare metal without an OS"
How are you going to be able to use all 3 cores? I'm a bit ignorant here, but I have seen some code from hardware guys that makes me shudder. They typically write their own loops and have a semi general understanding of task scheduling, but <honest admission=""> I tend to overthink things at times.

I have low level ways to activate the cores without a scheduler.

I am a long term fan of H2G2, and I always thought that the theme tune was created by the BBC Radiophonic Workshop. I just found out that the theme was actually written by the Eagles[^]. Someone smacked my gob, I'm that gobsmacked.

I didn't know that either!

This was my favourite theme tune for any programme from the BBC. Now that I know this, I can listen to it at any time. I am so happy.

I know. I wouldn't have thought that they were the usual suspects for a group like the Eagles.

Way back in University, my roommates DJed on the student radio station.
They borrowed the H2G2 tapes and we had an H2G2 party to beat all parties with the episodes playing.
We even created a version of the classic Penta-Galactic Gargle Blaster.
From what I remember, a good time was had by all.
I did wake up feeling like I had a brain the size of a planet.
