Audio capabilities of AT&T 3210- and PowerPC-based Macintosh products

This document covers the audio capabilities of the following products:

040 AV Macs: Apple Macintosh Centris 660AV; Quadra 660AV & 840AV

Power Macs:

AV Power Macs: Apple Power Macintosh 6100/60AV, 7100/66AV, 8100/80AV

Plain Power Macs: Apple Power Macintosh 6100/60,7100/66, 8100/80

[*]SI tools: Spectral Innovations’ DSP3210/ARTA Developer Toolkit

[*]SI board: Spectral Innovations’ AT&T3210-based, ARTA-compliant NuBus card

[*]ARTA Macs: 040 AV Macs & any Apple Macintosh with the SI board

MpegDec - discussion with developer, here, in 2002. Mentions Quadra AV DSPs, 56001s, and Photoshop cards.

>Apple uses the AT&T DSP3210 in the new Macintoshs. The DSP runs in>the Apple Realtime Architecture (ARTA) under a so called DSP OS.

>Is this identical to VCOS ?

VCOS and ARTA are extremely similar DSP OS's for the DSP3210/DSP3207,

but not identical. Both are real-time, multitasking, multiprocessing

DSP operating systems. Both have similar roots and ARTA is probably

best described as a "superset" of VCOS. The OS's are similar enough

to require minimal effort to port DSP modules from one domain to

the other. Thus, you have a solution if you are looking to do

cross-platform DSP development. ARTA runs on DSP-equipped

Macintoshes and VCOS predominantly runs on Windows systems but is

also supported on some others.

[*]PhotoBooster & PhotoEngine Q&A

The PhotoEngine is a NuBus card with 4 DSPs. The PhotoBooster (pictures) is an 040 PDS card with 2 DSPs.You need two files to use a PhotoEngine or PhotoBooster. The first file is a System Extension entitled "•Radius DSP". The second file is a Photoshop Plug-in, entitled "PhotoEngine Plug-in" or "PhotoBooster Plug-in"

[*]ThunderStorm, Thunder II, and all DSP-based Image Processing Accelerators Q&A

This document pertains to all Spectrum Power w/DSP, ThunderStorm, Thunder II, Thunder II•GX, PhotoSpeed, and upgraded Thunder/24 cards.
(IPA = Image Processing Acceleration) This software is the 'DSP code' that accelerates Photoshop resamples and filters on all SuperMac & E-Machines graphics cards with twin DSP16A chips, as well as the ThunderStorm Photoshop accelerators. The IPA software consists of a control panel and two plug-ins.

Q: What is the difference between the "ThunderStorm for Adobe Photoshop" NuBus card, the Thunder II Upgrade, the Spectrum Power DSP Upgrade, and the DSP daughtercard on the Thunder II family of cards?

A: Physical form is the only difference. The advantage of having the image-processing accelerator as a daughtercard is that this solution does not require an additional NuBus slot. The Spectrum Power DSP Upgrade is for the Spectrum Power•1152, as well as some E-Machines Ultura and Futura II cards.
