MSC8103
Digital Signal Processors
The Network DSP
The MSC8103, Freescale’s second
StarCore architecture-based DSP, is an
integrated network-ready processor that
enables systems designers to build new
capabilities into a broader range of products
with higher performance than ever before.
With its unique combination of a SC140
DSP core, programmable Communications
Processor Module (CPM) and PowerPC
bus interface, the MSC8103 offers
advanced signal processing performance,
flexible network connectivity and seamless
system integration.
The MSC8103 is designed for demanding
network infrastructure applications requiring
very high performance, large amounts of
on-chip memory and networking capabilities
such as 2.5G and 3G wireless infrastructure
systems, packet telephony solutions
voice-over-Internet Protocol (VoIP), and
packet aggregation. It can also provide a
network interface for a DSP farm of
MSC8102 devices.
Next-generation networking infrastructure
systems are based on a configurable open
architecture platform that supports real-time
voice, fax and data on a packet-switched
network. Through its integrated CPM, the
MSC8103 has the unique ability to connect
to the network, manage the Layer 2 and
Layer 3 protocols, and extract data directly
from the network.
Low-Cost Networking Performance
The MSC8103 is aggressively priced and
offers an optimal solution for applications
that do not require the EFCOP found on the
MSC8101. The MSC8103 provides up to
1200 MMACS of signal processing performance
in a low-power, 17mm x 17mm package.
The MSC8103 CPM is a programmable
32-bit RISC protocol machine that allows
connectivity to standard network backbones:
ATM, Fast Ethernet and fast TDM highways.
This 200 MHz CPM engine is derived from
Freescale’s popular MPC8260
PowerQUICC II microprocessor.
An integrated, 100 MHz, 64-bit PowerPC
bus interface allows easy connection to
multimaster PowerPC-based systems and
direct connectivity to PowerPC bus peripherals.
The MSC8103 contains 512 KB of static
RAM and a powerful 16-channel DMA
controller to facilitate data transfers between
the SC140 core, internal memory, CPM and
PowerPC bus interface. In addition, the
programmable MSC8103 memory controller
integrates support for a variety of external
memory devices and peripherals.
The MSC8103 also is designed to provide
cost-effective solution networking
infrastructure applications that enable
Freescale’s customers to bring these
products to market quickly, providing more
time-in-market and minimizing development
costs. Taking full advantage of the scalable
StarCore architecture, the MSC8103 is
pin-compatible with the MSC8101 and
utilizes proven development tools for
the MSC8101.
