ADSP-2126x. Instructions, control registers, or other facilities, required
to support the new feature set of the ADSP-2116x core include:
• Code compatibility to the ADSP-21160 SIMD core
• Supersets of the ADSP-2106x programming model
• Reserved facilities in the ADSP-2106x programming model
• Symbol name changes from the ADSP-2106x programming models
These name changes can be managed through reassembly by using the
development tools to apply the ADSP-2126x symbol definitions header
file and linker description file. While these changes have no direct impact
on existing core applications, system and I/O processor initialization code
and control code do require modifications.
Although the porting of source code written for the ADSP-2106x family
to the ADSP-2126x has been simplified, code changes will be required to
take full advantage of the new ADSP-2126x features. For more informa-
tion, see ADSP-21160 SHARC DSP Instruction Set Reference.
