That would be very cool to see

Are there any hardware multiplier blocks in the Altera device you use? (I'm not familiar with Altera)
In such case you could accelerate the softcores mult instructions, and thereby speed up the mp3 decoding significantly.

The hardware multiplier unit is key to being able to play high bit-rate (or even low bit-rate) MP3s in real-time due to the vast number of multiplications done as part of the MP3 decode algorithm.

When profiling the software on the software simulator, a 1 second MP3 clip @ 128kbps performed 290,304 multiply add operations (MADD64) and 46,080 multiply shift operations (MULSHIFT32).

It seems that mp3 playback is a really important feature to the Amiga community; thereby it might be worth the effort.

Same here, a dual core laptop is not enough I had to switch to my Haswell main rig to be able to watch this video without stuttering. What kind of video compression is this ?

it is 720HD i wanted it to be a really good resolution and best sound quality,i gonna do another video up prob today/tomorrow to show the workbench a little more and some of the speed increases. I'll drop the next one down a bit

mabbe start and then pause to try to buffer it to see if that helps

Kipper's video played fine on my Phenom 9500 (older quad core cpu)

Oh no, please, don't lower the quality. Maybe make it a downloadable MKV. Perhaps this browser thing is messing things up.

internet download manager will allow you to download videos off the internet, works for pretty well all streaming too

no problems here on an AMD Athlon 4850e!

btw this is really amazing!

[Zippy Zapp]

Wow, now I wish I had an A600. Hope they finish the 500 version soon! I know I can buy an ACA version but if I understand correctly this one can be upgraded via firmware to faster speeds?

Video played fine on my 2008 Macbook Pro (Core 2 Duo).

Hey where did you find our cat!?! We lost him a few years back and I swear that is him or his twin! LOL

Funny that about the cat, my daughter found her shivering under the car and snuck her in the house, fed her leftover pizza etc for about 3 months before i found out. Now she is a professional moocher... (The cat too!!

As for the A500, i think it is soon going to be renamed as the A5000

LOL. Well I don't think our cat walked to Canada from California.

It has always been a great system and with all the add-ons coming out these days it is tough to beat! That would be fitting.

Wooah, that's brilliant!

You´re Awesome, i told you this a few times already ;
But, i have to do it again ..... so here we gooooo ...

Man, you´re awesome !

There is multiple factors that need to be solved (most of them critical from audio quality perspective)

First Amiga have no 48/44.1k sample rates and as such sample rate conversion is required, second Paula is 8 bit and to produce high quality audio oversampling (at least 2 - 4 times) is required, at third noise shaping need to be used to create 16 bit or better quality.
All those 3 things are absolute must (and it will be good to solve them at hardware level).
Perhaps even pseudo DMA to offload CPU from software load (audio data need to be sent with very strict time constrains).

@Kipper2k
No FLASH no fun.

A600 + Vampire playing MP3 only with 30% CPU Usage

[amigoun]

The core is emulating 68020 or 68000?
I think 020+ is required for MP3 playback.

[Foul]

Pure 68000 and some fragments of 020/040/060 if i understand correctly

as BigGun say :

[09/02/2015 18:26] <BigGun1> So 3 month ago Phoenix was to 80% an 68000 and to 20% an 68060
[09/02/2015 18:26] <BigGun1> today Phoenix is to 99.9% an 68060
