Documentation
This Data Sheet is a summary description of the ZR38650’s
functional operation and command and response operation as
well as electrical, timing and physical specifications. The
complete source of information on its physical function and pro-
grammed operation including instruction set is the “ZR38650
Users Hardware Manual”. Also available are the “ZR38000
Family Simulator User’s Manual” and the “ZR38000 Family
Assembler/Linker User’s Manual.”
The following Application Notes are currently available that
contain additional design related information:
“Designing with the ZR38600 Audio Processor”
“Bass Redirection for the ZR38600 Audio Processor”
“Audio Source Type Detection for the ZR38600 Audio
Processor”.
New Application Notes are added on a regular basis and are
available from sales representatives.
Demonstration Board
The ZR38600 Demonstration Board is a stand-alone Dolby AC-
3 and MPEG audio decoder. The demonstration board is
equipped with three high-quality, stereo 20-bit DACs and one
stereo 20-bit ADC for microphone or line input. The input bit-
stream is fed to the board in S/PDIF format. Both optical and
coaxial interfaces are supported. Decoding and operation func-
tions are selected via push buttons and a large LCD display is
provided for status information. The demonstration board is
equipped with a PC interface for controlling operation with the
standard function commands and responses and for loading of
custom programs. An ICE interface is also available on the
board.
Software Development Kit
Two software development tools provide all that is necessary to
write, assemble, link, simulate, and debug programs in native
ZR38001 code for the ZR38650. They run on a Pentium PC
under Microsoft Windows 95. The ZR38000 Family Assem-
bler/Linker translates the assembly language code, including
macros, to object code which can be linked with data files and
other object code to generate a complete executable program
file. The ZR38000 Family Simulator accurately executes the
program file while permitting full displays of registers and
memory along with single-step operation and breakpoints for
debugging. Both are of modern design being highly interactive
and with macro and symbolic naming support throughout.
The ZR38650 is software compatible with Zoran’s previous gen-
eration ZR38000 family devices.
