Re: FrontBench: using Frontier as a benchmark
That’s rather faster than the original TF536 with @agranlund’s last firmware release. You were saying that your version didn’t throttle down to 8MHz when accessing the ST hardware. Could this be retrofitted to work on the original card?

Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.

Re: FrontBench: using Frontier as a benchmark
Basically no. I revised the hardware and firmware for the ST edition.stephen_usher wrote: ↑Sun Feb 13, 2022 11:40 pm That’s rather faster than the original TF536 with @agranlund’s last firmware release. Could this be retrofitted to work on the original card?
It runs at 50MHz all the time even when accessing the ST bus.stephen_usher wrote: ↑Sun Feb 13, 2022 11:40 pm You were saying that your version didn’t throttle down to 8MHz when accessing the ST hardware.

Just because a lot of people agree on something, doesn't make it a fact. ~exxos ~

Re: FrontBench: using Frontier as a benchmark
So, the techniques used by your changed firmware couldn’t be applied to agranlund’s code to speed the original design up then?

Re: FrontBench: using Frontier as a benchmark
I had problems with the original 536 on the H4 which is why I designed a new one with fixes I knew were needed for the ST. I re-wrote pretty much the whole firmware. Which wasn't easy as I'm a n00b at verilog.stephen_usher wrote: ↑Mon Feb 14, 2022 4:50 am So, the techniques used by your changed firmware couldn’t be applied to agranlund’s code to speed the original design up then?

Re: FrontBench: using Frontier as a benchmark
Fair enough. I do remember seeing your pain of learning Verilog during your development process.
The TF536 with the current firmware is pretty hobbled unless the task is purely processor bound and using Fast-RAM exclusively.

Thanks Stephen. What VBL rate is that at, please?

Re: FrontBench: using Frontier as a benchmark
This is odd. I've never seen any difference between TOS and EmuTOS. Frontier barely touches the OS.
Is EmuTOS in ROM?
(and I assume you mean 536?)

The only one that the TT can do, 60Hz (VGA-ish).

Ah, I didn't know it couldn't drive an old-school monitor. That's a pity. You'd be up around 3.5k if it could do RGB PAL!

Re: FrontBench: using Frontier as a benchmark
536 yep oops.
I think its "lower ram variables" ? I will try and test the original MAPROM later, but it never worked for me. I don't get the speed up either, but thats the results I got.
But I have also noticed something peculiar Speed comparisons as well where EMUTOS when at double speed in GB6 tests than TOS206. but I really have not had time to look into it all. But with my limited knowledge of how the OS works am not really " qualified" for investigating all that stuff.
