7 SPLITTER FOR SHARC AND
TIGERSHARC PROCESSORS
This chapter explains how the splitter utility (elfspl21k.exe) is used to
convert executable (.dxe) files into non-bootable files for ADSP-21xxx
SHARC and the ADSP-TSxxx TigerSHARC processors. Non-bootable
PROM image files execute from external memory of a processor. For TigerSHARC
processors, the splitter utility creates a 32-bit image file. For
SHARC processors, the utility creates a 48-/40-bit image file or an image
file to match a physical memory size.
In most instances, developers working with SHARC and TigerSHARC
processor use the loader utility instead of the splitter. One of the exceptions
is a SHARC system that can execute instructions from external
memory. The non-bootable PROM image files are often used with
ADSP-21065L processor systems, which have limited internal memory.
Refer to “Introduction” on page 1-1 for the splitter utility overview; the
introductory material applies to both processor families.
Splitter operations are detailed in the following sections.
“Splitter Command Line” on page 7-2
Provides reference information about the splitter utility’s command-line
syntax and switches.
“VisualDSP++ Interface (Split Page)” on page 7-9
Provides reference information about the splitter utility’s graphical
user interface.
