MM-DSP
SERIES
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
C I F
.
®
to four CAB
an unlimited number of CAB
outputs each). The CAB units are audio
bridges that port audio on and off a
standard 10/100BaseT Ethernet network
¨
utilizing CobraNet
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.
