ADSP-2192 DSP Booting
An ADSP-2192-12 DSP can be boot-loaded through its PCI or USB
interface. For PCI loading, the loadable executable (
.EXE
) must reside in
the PC host’s memory space before it is loaded into the DSP.
The ADSP-2192-12 loader repackages
.DXE
files and associated
.OVL
and
.SM
files, produced by the linker, into an
.H
file for use with a run-time
loader (RTBL). The RTBL is a drive implemented by the user; the RTBL
is responsible for transporting the loadable executable into the DSP. Visu-
alDSP++ includes a reference RTBL that can be used to boot-load an
ADSP-2192-12 EZ-KIT Lite evaluation system on Windows 98 and
Windows 2000 platforms.
You can run the loader from a command-line or directly from within the
Vi+ IDDE. When working from the Vi+, specify the
loader options via the
Load page of the Project Options dialog box.
!
Option setting on the Load page correspond to switches displayed
on the command line.
To ensure correct operation of the loader, familiarize yourself with:
• “ADSP-2192 DSP Reset Types” on page 4-2
• “ADSP-2192 DSP RTBL” on page 4-4
• “ADSP-2192 DSP RBTL and Overlays” on page 4-8
ADSP-2192 DSP Reset Types
The ADSP-2192 DSP supports booting via the PCI interface or the USB
interface. The internal ROM includes a small boot kernel program, which
determines how the DSP boots.
