Sumitomo Realizes Over 100-Gbps Performance in Its LDPC System
Leveraging Stratix IV GX FPGAs
Altera
Corporation (NASDAQ:ALTR) today announced Sumitomo Electric
Industries, Ltd. is leveraging 40-nm Stratix® IV GX FPGAs in
an advanced low-density parity-check (LDPC) system. Altera's
high-performance, high-bandwidth Stratix IV GX FPGAs enabled Sumitomo to
develop a high-speed measurement system that verifies the forward error
correction (FEC) code for high-speed digital signal processing (DSP).
Sumitomo's high-throughput LDPC system features a novel encoding and
decoding algorithm capable of improving the signal quality in
applications that require highly efficient data transmission, such as
image processing, next-generation optical memory, high-definition (HD)
digital video broadcasting, mobile broadband communications and optical
networking.
"Altera's Stratix IV GX FPGA provides us with a cost-effective,
single-chip solution that delivers best-in-class performance and data
rate speeds, allowing us to realize over 100-Gbps performance in our
LDPC system," said Mr. Takashi Maehata, assistant general manager,
transmission system department, information and communication
laboratories, Sumitomo Electric Industries. "Obtaining this level of
performance would not have been possible without Stratix IV GX FPGAs and
their integrated 8.5-Gbps transceivers. As a result of using Altera's
Stratix IV GX FPGAs, our LDPC system achieves a throughput of 132-Gbps
encoding and 24.48-Gbps decoding."
Altera® Stratix IV GX FPGAs and Quartus® II
design software provide Sumitomo with a seamless development environment
from algorithm to automatic HDL generation. The Stratix IV GX FPGA-based
LDPC system interfaces with a multi-Gigabit analog/digital converter
(ADC) and features a Nios® II embedded processor. The
embedded processor operates a TCP/IP protocol stack and facilitates the
LDPC encoder and decoder. The system's circuits were developed using the
Quartus II software and the DSP Builder and SOPC Builder tools.
Luanne Schirrmeister, senior director of component product marketing at
Altera, stated, "Today's leading-edge, data-intensive systems are
increasing the demand for high-bandwidth devices that are capable of
rapidly processing large amounts of data. Our 40-nm Stratix IV FPGAs
continue to push the technology envelope in terms of performance and
data-rate speeds, allowing companies like Sumitomo to develop advanced
systems that previously were not possible."
About Stratix IV FPGA Family
Altera's 40-nm Stratix IV FPGAs deliver the industry's highest density,
highest performance and lowest power, while providing proven transceiver
and memory interface technology. The high-end FPGAs feature three
variants, a non-transceiver enhanced (E) version and two transceiver (GX
and GT) versions. The GX and GT variants feature integrated transceivers
that provide an unprecedented level of system bandwidth (up to 8.5 Gbps
and 11.3 Gbps respectively) with superior signal integrity. Stratix IV E
FPGAs are high in density and rich with embedded memory and DSP
resources. For more information on the market-leading features offered
