DSP 3210 drivers & tools
This package contains drivers and several tools to use and operate the
DSP 3210 on AA3000/AA3000+ motherboards.
Samples and Demos **********************************
dsp3210devtest: A tool for comprehensively testing the DSP drivers
(dsp3210.device and dsp3210.resource) and the hardware as regards
CPU vs DSP memory access. It executes DSP programs that hammer host
memory in all directions and of all kinds (ChipRAM and FastRAM). If
this shows errors (other than IO errors), there is a hardware problem
at hand, most likely GAL timing issues. To make sure, the timing of
the GALs is correct, let this run for at least 1000 passes. It
should exit with zero errors.
This tool has two important limitations:
1) The FastRAM tests are performed with FastRAM of the highest
priority. If you have an accelerator board with local RAM, it will
usually use that - timing errors with motherboard or Zorro RAM might
therefore not be detected.
2) What this tool is incapable to uncover are potential issues with
the onboard SCSI controller in connection with the DSP.
Please see docs/STATUS.doc for more information.
examples/dsp3210mandel: A Mandelbrot application using the DSP via
dsp3210.device and dsp3210.library. This is an adaption of Wrangler's
"mandel_dsp", with all hardware hacks removed and replaced by driver
functions. Comes in three versions that differ in how the DSP tells
the CPU it's finished. Meant as demos for the different methods the
drivers support and offer.
Based on dsp3210run (used as DSP-handling skeleton), Mandel by Erik
Trulsson, ARTABROT by George T Warner.
examples/dsp3210run: Runs a given DSP program. Is a sample and skeleton
for new applications at the same time. It fully utilizes the drivers in
this package. A suitable demo DSP program is DSP/testprogram.
examples/dsp3210libtest and examples/dsp3210clibtest:
Show usage of dsp3210.library, by loading and relocating the DSP
programs in examples/DSP.
makeobjectfile: This utility creates an object file out of any binary,
and the main purpose here is to create object files out of DSP binaries,
ready to link to your own application with blink, slink or and other
Amiga standard linker.
dsp3210.library *************************************
This library helps applications to use the DSP by handling binaries created
by the d32 tools (eg d32as and d32cc).
It currently supports
- calculating the required memory for the relocated binary
- relocating a DSP binary to a target memory address
- loading and relocating a DSP binary in one single step (DSPLoadMod())
- resolving local and global symbols accross several DSP binaries
- additional application-provided global symbols
- searching for global symbols
- converting a binary with little-endian file structures to big-endian
Please see the code samples for more information, first and foremost
dsp3210run.
Source and developer files included.
DSP 3210 Resource & Device ***************************
Low level drivers for the DSP.
1) dsp3210.resource
The dsp3210.resource ("resource") is the base layer.
dsp3210.resource is an executable which is run from CLI at startup, for
example from user-startup. It creates the dsp3210.resource.
2) dsp3210.device
This is placed in devs: and is a middle layer between the dsp3210.resource
and the user application.
Please see the included documentation and examples for more information
on how to use this.
