Freescale Semiconductor Audio DSP Performs Big in Small Package; DSP56374 Enables Customized High-Quality Audio on the Road and in the Home
AUSTIN, Texas—(BUSINESS WIRE)—Oct. 4, 2004—
Freescale Semiconductor (NYSE:FSL) has combined digital
signal processor (DSP) performance and a low price point for audio
applications that require small board space. The DSP56374 furthers the
company's commitment to the digital audio market by offering a device
that marries speed, memory and value for automotive and consumer
entertainment.
In the car, the DSP56374 offers sound equalization and audio
delays to provide "smart" audio that tailors sound based on where
vehicle occupants are sitting or by specific car model. This same
device extends high-quality sound to "home theatre in a box," DVD and
shelf systems, as well as next-generation television platforms. The
DSP56374 occupies a small footprint, critical for these audio
applications, in which space is at a premium.
The DSP56374 provides significant performance-for-price value. It
is also code-compatible with Freescale's 56000 and 56300 DSP families,
which greatly reduces new product design time by enabling code reuse.
"Once again, good things come in small packages. The DSP56374
delivers more speed, memory, comprehensive peripherals and signal
processing capability than you would expect at this price point," said
Bill Pfaff, vice president and general manager of Freescale's Digital
Audio, Radio and Telematics business. "It also extends our leadership
in the digital audio market and specifically the DSP56300 family."
Freescale's DSP technology has been a leader in the industry since
the first 24-bit DSP was introduced in 1987. Since then, top names in
the industry have standardized on Freescale technology to develop
applications that deliver high-quality sound to listeners in their
homes and vehicles and in commercial settings around the world.
The DSP56374 is a consumer-qualified device, with plans for full
AEC automotive qualification in 2005. The DSP56374 can perform various
audio equalizing algorithms, compression, speaker compensation, tone
control, fade and balance functions, as well as audio sound-field
processing algorithms via built-in software in the ROM developed by
Freescale using the widely adopted plug-and-play software
architecture. Matrix decoders such as Dolby(R) Pro-Logic IIx and
DTS(R) Neo:6 are available on certain ROM versions of the parts.
Customers are also able to develop their own software by downloading
software to the on-board RAM.
