Applications can boot the internal memory of the ADSP-21065L at sys-
tem powerup from an 8-bit EPROM, a host processor, or external
memory. The BMS (Boot Memory Select) and BSEL (EPROM Boot) pins
select the boot source. Either 8-, 16-, or a 32-bit host processor can boot
the ADSP-21065L.

The ADSP-21065L is supported with a complete set of software and hard-
ware development tools, including the EZ-ICE
®
VisualDSP
and SHARC
The same EZ-ICE hardware that you use for the ADSP-21060/62, also
fully emulates the ADSP-21065L, with the exception of displaying and
modifying the two new SPORTs registers. The emulator will not display
these two registers, but your code can still use them.
Both the SHARC Development Tools family and the VisualDSP inte-
grated project management and debugging environment support the
ADSP21065L. The VisualDSP project management environment enables
you to develop and debug an application from within a single integrated
program.
The SHARC Development Tools include an easy to use Assembler with
instructions based on an algebraic syntax; a linker; a loader; a cycle-accu-
rate, instruction-level simulator; a C compiler; and a C run-time library
that includes DSP and mathematical functions.
Debugging both C and Assembly programs with the VisualDSP debugger,
you can:
• View mixed C and Assembly code
• Insert break points
