Flexible Architecture
The ESP-88 employs a flexible, modular architecture.
The flexible architecture provides two levels of DSP
performance – up to 32 general-purpose I/O and up to
64 digital audio channels – or up to 32 analog audio
channels.
The base model ESP-88, includes a DSP card, two 4x4
Mic/Line cards and one GPIO card. In this configura-
tion, four audio and one GPIO slot are available for
expansion.
Optional Cards
Three types of optional cards are available: DSP
expansion; GPIO; and Audio.
DSP expansion card
Daughter card for main DSP card. Increases
performance by 300%. One card can be added to
an ESP-88.
GPIO card
Fits in one of the two GPIO slots. Eight control
inputs and eight control outputs. One GPIO card
can be added to an ESP-88.
