This hardware reference is a companion document to the
ADSP-2136x/ADSP-2137x SHARC Processor Programming Refer-
ence. The programming reference provides information relating to
the processor core, such as processing elements, internal memory,
and program sequencing. It also provides programming specific
information, such as complete descriptions of the ADSP-21xxx
instruction set and the compute operations, including their assem-
bly language syntax and opcode fields.
What’s New in This Manual
Revision 1.0 of the ADSP-21368 SHARC Processor Hardware Reference is
the first general release of this manual. The following changes should be
noted.
• In the preliminary version this manual was titled ADSP-2136x
SHARC Processor Hardware reference for the ADSP-21367/8/9 Pro-
cessors. The title change to ADSP-21368 SHARC Processor
Hardware Reference was done to reflect the fact that the
ADSP-21368 processor contains the super set of features of the
ADSP-21367 and ADSP-21369 models as well as the new
ADSP-21371 and ADSP-21375 models.
• This version of the manual contains information about the
ADSP-21371 and ADSP-21375 SHARC processors. These new
models contain the same core as the ADSP-21367/8/9 processors
