MSC8156/MSC8156E
Broadband Wireless Access DSP
Overview
The MSC8156/MSC8156E is a six-core DSP
based on Freescale’s new SC3850 StarCore
technology and designed to advance the
capabilities of wireless broadband equipment.
It delivers industry-leading performance and
power savings, leveraging 45 nm process
technology in a highly integrated SoC to
provide performance equivalent to 6 GHz of a
single core device. The MSC8156/MSC8156E
will help equipment manufacturers and
carriers create solutions and services that
enable near-term, mainstream adoption of
next-generation wireless standards such as
3G-LTE, WiMAX, HSPA+ and TDD-LTE. The
device is designed to lower system costs by
integrating functionality into a single
Advanced 45 nm, six-core DSP for 3G-LTE, TDD-LTE,
WiMAX, 3GPP-HSPA and TD-SCDMA
device that previously required multiple
discrete parts.
The MSC8156/MSC8156E DSP delivers a
high level of performance and integration,
combining six fully programmable new
and enhanced SC3850 DSP cores, each
running at up to 1 GHz with an architecture
highly optimized for wireless infrastructure
applications. Developed by Freescale and
integrated on chip, the MAPLE-B baseband
accelerator supports hardware acceleration
for Turbo and Viterbi channel decoding and for
DFT/iDFT and FFT/iFFT algorithms. An internal
RISC-based QUICC Engine subsystem
supports multiple networking protocols
to guarantee reliable data transport over
packet networks while significantly offloading
processing from the DSP cores. The optional
security engine core (SEC) in the MSC8156E
accelerates data plane encryption/decryption
and code protection with minimal DSP core
intervention.
The MSC8156/MSC8156E embeds large
internal memory and supports a variety
of advanced, high-speed interface types,
including two Serial RapidIO
®
interfaces,
two Gigabit Ethernet interfaces for network
communications, a PCI Express
®
controller,
two DDR controllers for high-speed, industry
standard memory interface and four multi-
channel TDM interfaces.
