NORWOOD, Mass.--BUSINESS WIRE--Analog
Devices, Inc. today announced that Silentium
Ltd., developers of spatial &
broadband active noise control ANC technologies, has selected Analog
Devices’ Blackfin processors to power their ANC products. Utilizing
low cost, powerful Blackfin processors for their core ANC technology,
the S-Cube™ Controller, Silentium is able to deliver more than 10dB A
broadband noise reduction covering the entire audible range and, in
addition, deliver from 100Hz up to 2KHz point to zone spatial noise
reduction.
“Analog Devices’ low cost, high performance processors are central to
our success in delivering exceptional ANC functionality”
Active noise cancellation minimizes the unwelcome “noise” often
generated by electronic equipment. ANC is used in a full range of
applications and industries, including server and networking equipment,
air treatment and air conditioning machinery, automotive and aircraft
cabins, white goods, and more. Silentium’s Blackfin-based S-Cube
Controller technology enables product developers to easily incorporate
active noise control into existing products or provides board-level ANC
components to incorporate into custom hardware designs. The company also
offers off-the-shelf noise control products including sound-proofed rack
mounted cabinets and enclosures, docking stations for workstations and
servers, and duct work for air conditioning systems.
“Analog Devices’ low cost, high performance processors are central to
our success in delivering exceptional ANC functionality,” said Yoel
Naor, director of products, Silentium. Blackfin’s extensive peripheral
connectivity allowed us to take a whole-system design approach, giving
us both a powerful platform and the design flexibility necessary to
develop low-cost, highly effective low to medium frequency solutions for
both our end users and OEM customers.”
Silentium’s S-Cube solution, unlike previously designed ANC systems,
extends the low frequency range of signals up to 1800Hz with multiple
sound tone capability, eliminating the need for error microphones. The
high performance Blackfin BF533 600 MHz processor executes Silentium’s
proprietary algorithms to perform system identification, phase and
spatial matching, and to adaptively follow the changes in noise
spectrum, achieving extraordinary results of about 10dB A noise
reduction on top of passive noise reduction obtained by using only
traditional acoustic materials.
The fully programmable Blackfin BF533 16/32-bit core is capable of
operating at up to 756 MHz/1512 MMACS and has up to 148kB of on-chip
SRAM memory. Effective for intensive data processing applications like
ANC, the BF533 has two dual-channel, full-duplex, synchronous serial
ports and 12 DMA channels supporting one- and two dimensional data
transfers. The power efficient Blackfin processor’s self
contained dynamic power management capability, with power consumption
starting as low as .8 V to 1.45 V, allows the operating frequency and
voltage to be independently manipulated to dynamically meet the
performance requirements of algorithm execution, enabling exceptional
power optimization. Silentium’s design takes advantage of the Blackfin
BF533’s expansive, standard integrated peripheral set, including, UART,
SPORT, and SPI peripherals.
Leveraging Analog Devices’ extensive signal processing expertise, the
ANC solution incorporated additional ADI components, including the AD73311L
Codec, a single channel, 3V front end processor for general purpose
speech and telephony and the ADM6711
microprocessor reset generator circuit to provide a reset signal on
power-up, power-down when supply voltage falls below a preset threshold.
“High performance signal processing capability coupled with extensive,
integrated peripheral options enable customers like Silentium to bring
high precision, feature-rich products to market,” said Colin Duggan,
product line director, General Purpose Digital Signal Processor
Division, Analog Devices. “Blackfin’s high performance at a low price
point made it the ideal processor for Silentium’s products, which are
designed for price-sensitive end users and OEM customers.”
