General Description
The Zoran ZR38601 is the latest digital audio processing member of the
ZR38000 high-performance, programmable digital signal processor product
line. It is especially configured with peripherals, I/O capability, and software
for digital audio. Today, quality digital audio starts with a primary decoding
function, adds appropriate data stream protocols, and interfaces with I/O con-
figurations to match the application. The ZR38601 has these primary decode
and protocol software functions yet has processing cycles left for additional
product-distinguishing features. The ZR38601 also has the necessary flexibili-
ty in system I/O and hardware configuration.
The ZR38601 is pin and instruction-set compatible with the earlier ZR38600,
but with a higher 50-MIPS processing rate and larger internal program and
data RAMs and ROM. These features provide new 96-kHz sample rate
S/PDIF decoding, and increased processing cycles and memories for addi-
tional functions. New hardware features are a programmable timer, a Z2C
serial host interface, and more support for the 24-bit I/O data formats.
Functions
Dolby Digital and MPEG with variations are the primary decoding functions in
use today. The ZR38601 has these and their associated test function with the
required set-up, operation, and system functions to make them usable in an
end-user product. In addition, an ever increasing number of SiliconSoftware
functions can add special enhancing and differentiating features to products.
Primary Decoding and Test Functions
Dolby Digital
Dolby DigitalThe figure shows the simultaneous S/PDIF input
and 5.1-channel Digital-to-Analog Converter (DAC) outputs of this primary
digital audio function, the six-channel Dolby Digital decoder.
Or with four channels of Pro Logic output in either of two DAC forms: four
channels directly or to an analog Pro Logic decoder
PCM + Pro Logic
With two-channel PCM inputs, the choice of functions is
four-channel Pro Logic decoding or two-channel stereo mixing, including
upmixing from only one input channel to two.
MPEG
The MPEG-1 decoder accepts either MPEG-1 or MPEG-2 input
streams and produces either Pro Logic DAC outputs or two-channel stereo in
DAC form.
Pink Noise
A six-channel pink pseudo-random noise generator function is
included for user testing of speaker balance in their listening space. Individual
speakers can be enabled in any combination.
SiliconSoftware Functions
SiliconSoftware is a group of additional functions for the ZR38601 provided
by Zoran or third-party suppliers that can add special features now or provide
new functions in the future.
