B.9.3

CPLD Upgrade

The CPLD offers a functionality to reprogram its configuration data under host software
control. The procedure is not FAIL-SAFE status. This means if a reprogramming procedure fails,
the whole card becomes unusable and needs to be reprogrammed via H/W (download cable).

B.10 DSP Array

The PCIE-8120 DSP Array can be populated with up to 12 instances of Octasic's DSP OCT2224M
System-On-Chip device, which is specialized for media gateway applications. For more
information on the Octasic DSP OCT2224M, refer to the OCT2200M Hardware Specification listed
in

.

The following sections describe specific aspects of the PCIE-8120 design:

B.10.1 DSP Overview

The Octasic OCT2224M DSP is part of the OCT2200 series of devices which is a family of Digital
Signal Processors (DSP) based on the Opus 2 architecture developed by Octasic. It is targeting
voice and video applications for telephony infrastructure applications.

The OCT2224M is composed of five major subsystems:

The Opus2 DSP subsystem

The DDR Memory Subsystem

The High-speed I/O Subsystem (Ethernet MAC Engines)

The Resources Subsystem (GPIO)

The Maintenance Subsystem (Boot Controller)

The main features of the OCT2224M are:

24 Opus2 cores with 144k bytes of L1 memory per core

C programmable DSP

484-Pin BGA 1.0mm pitch

4W typical power consumption

Secure custom booting capability
