Vi+ Loader Manual 4-7
for 16-Bit Processors
ADSP-2192-12 DSP Loader
To create an
.EXE
file from Vi+
1. From the Load page of the Project Options dialog box, specify the
input (
.DXE
) files under Core 0 and Core 1 .
2. From the Post Build page, configure one or more command lines
to execute the RTBL.
3. Run the project. This generates the
.H
file and creates the
.EXE
file.
The
.EXE
file, which is executed on the end-user system, traverses the data
structures (
.H
) created by the loader and subsequently compiled by the
RTBL. The content of these data structures are downloaded to the
ADSP-2192-12 DSP through a user-provided Windows driver.
!
A program running in virtual memory space (as do all Windows
applications) cannot access the PCI-mapped memory of the
ADSP-2192 DSP directly. A driver is mandatory.
Reference RTBL
Creating the RTBL and driver can be a complex task, especially the first
time. To facilitate the process, Vi+ includes a reference RTBL in
the form of a Microsoft + 6.0 project named
reference_rtbl.dsp
. This project is located in the
ldr
subdirectory of
your Vi+ installation directory. Refer to the files in the project
for information on the operation of the RTBL and the provided driver
interface.
The RTBL downloads the code via the PCI bus to the ADSP-2192-12
EZ-KIT Lite evaluation system through the EZ-KIT Lite’s PCI driver.
This reference can serve as an example for traversing and using the data
structures emitted by the loader. Then download those structures to the
target through a driver.
!
The reference RTBL provided with the EZ-KIT Lite evaluation
system does not support USB booting.
