Description
The MediaMatrix
¨
MM-DSP Series DPU
(Digital Processing Unit) boards are the
heart of the MediaMatrix Mainframe DSP
engine. Each DPU contains four Motorola
¨
56002 DSP chips and is capable of
greater than 100 MIPS (Million Instructions
Per Second). The MM-DSP Series utilizes
PeaveyÕs exclusive V-Stac
ª
coding which
doubles the processing efficiency and
resulting capabilities of each DSP chip.
Each board also handles 32 input and 32
output audio channels, and performs 24-
bit processing. The MM-DSP Series uses
double-precision filtering for superior
accuracy of audio filtering frequency
centers and filter skirts.
There are three models in the MM-DSP
Series. The first is the MM-DSP DPU for
processing standard audio sources via up
to four 8800 Series BoBÕs (8-channel-in by
8-channel-out A-to-D/D-to-A Break-out
Boxes). The second is the MM-DSP-AES
for processing 32-channels-in by 32-
channels-out of AES/EBU standard digital
audio (16 channels each of stereo AES3
signals). This is done via the MediaMatrix
16XT AES/EBU transformer-isolating
interface box. The third is the MM-DSP-
CN for processing audio ported to or from
an Ethernet network. This is done via up
to four CAB
ª
8iÕs (eight-inputs each) and
an unlimited number of CAB
ª
8oÕs (eight-
outputs each). The CAB units are audio
bridges that port audio on and off a
standard 10/100BaseT Ethernet network
utilizing CobraNet
¨
protocol.
The MM-DSP model has a software-
selectable sample-rate that matches it to
the sample-rate of the MM-8800 Series
BoB to which it is interfaced. Depending
on the BoB used, either 32, 44.1, or
48 kHz can be chosen. The MM-DSP-AES
also has a software-selectable sample-
rate. It supports 32, 44.1, and 48 kHz
sampled AES/EBU standard digital audio.
The DSP-CN operates only at a 48 kHz
sampling rate.
