Thanks
to Freescale Semiconductor and its MSC8156 digital signal processor
(DSP) solution, Huawei was able to take the performance of its
TD-SCDMA wireless networks to new heights, allowing for the delivery
of scalable, low-cost, energy-efficient base stations.
Freescake's
MSC8156 DSP combines six fully-programmable enhanced 1 GHz SC3850 DSP
cores to provide a high level of performance and integration. Its
MAPLE-B accelerator is integrated on-chip and supports hardware
acceleration for Turbo and Viterbi channel decoding as well as the
DFT/iDFT and FFT/iFFT algorithms. It supports multiple networking
protocols through its internal RISC-based QUICC engine subsystem,
ensuring data is reliably transported through packet networks and
significantly offloading processing from the DSP cores.
In
addition to having a large embedded internal memory, the MSC8156
supports a variety of advanced high-speed interface types. It has two
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. Its pin compatibility with all MSC825x
and MSC815x DSP devices grant the MSC8156 a high degree of
scalability.
“Huawei
is committed to offering customer-centric solutions and products,”
said Chen Xi, chief technology officer of Huawei’s Wireless Network
Business Unit, ” which leverage the performance and programmability
of Freescale’s MSC8156 DSP.”
According
to Mr. Xi, Freescale's highly efficient DSP cores and accelerators
significantly enhanced overall base station efficiency. Huawei gained
the ability to boost system flexibility and provide the industry’s
highest number of TD-SCDMA carrier waves in a base station.”
