5.4 DSP Farm
The OCTASIC DSP-DIMM module contains 4 OCTASIC-OCT2224M Digital Singal Processors
(DSP). These DSP modules are not hot swappable, but they can be exchanged or assembled in
the field. These DSPs are connected to the infrastructure of one GbE link per DSP.
5.4.1 Digital Signal Processing
The OCT2224M is part of the OCT2200 series of devices, which is a family of DSP, based on the
Opus2 architecture, developed by Octasic. The OCT2224M is for voice and video applications
for telephony infrastructure applications.
