DSP/BIOS User Guide

Paul Raine
Intellectual 580 points

Hi,

We have inherited a project that uses DSP/BIOS on a TMS320C55 device.

I'm looking for a relevant user guide for DSP/BIOS.

The header files in the code are labeled:

* Copyright 2012 by Texas Instruments Incorporated.

* @(#) DSP/BIOS_Kernel 5,2,5,44 09-06-2012 (cuda-u44)

But I could only find a user guide for version 5.42 of DSP on the TI website.

This document did not have any information on SEM_pendBinary/SEM_postBinary, which is well used in my project.

So I suspect I don't have the latest.

Paul

    SPRU404Q is "TMS320C55x DSP/BIOS 5.x API Reference Guide". Section 2.23 describes SEM, and include SEM_pendBinary (p361) and SEM_postBinary (p363). It is included with DSP/BIOS 5.42 as distributed with CCS 5.5 (and I guess with the standalone DSP/BIOS download, or you can just download directly from TI). Issue Q (the last letter of the document name) is dated Aug 2012, so it doesn't seem far off what you have.
