PrefaceRead This FirstAbout This ManualDSP/BIOS gives developers of mainstream applications on TexasInstruments TMS320 DSP devices the ability to develop embedded real-timesoftware. DSP/BIOS provides a small firmware real-time library and easy-touse tools for real-time tracing and analysis.You should read and become familiar with the TMS320 DSP/BIOS APIReference Guide for your platform. The API reference guide is a companionvolume to this user’s guide.Before you read this manual, you should follow the "Using DSP/BIOS"lessons in the online Code Composer Studio Tutorial. This manual discussesvarious aspects of DSP/BIOS in depth and assumes that you have at least abasic understanding of other aspects of DSP/BIOS as found in the helpsystems.Notational ConventionsThis document uses the following conventions: Program listings, program examples, and interactive displays are shownin a special typeface. Examples use a bold version of thespecial typeface for emphasis; interactive displays use a bold versionof the special typeface to distinguish commands that you enter from itemsthat the system displays (such as prompts, command output, errormessages, etc.).Here is a sample program listing:Void copy(HST Obj *input, HST Obj *output){PIP Obj*in, *out;Uns*src, *dst;Unssize;}iii
Related Documentation From Texas Instruments Square brackets ( [ and ] ) identify an optional parameter. If you use anoptional parameter, you specify the information within the brackets.Unless the square brackets are in a bold typeface, do not enter thebrackets themselves. Throughout this manual, 54 can represent the two-digit numericappropriate to your specific DSP platform. If your DSP platform is C62xbased, substitute 62 each time you see the designation 54. For example,DSP/BIOS assembly language API header files for the C6000 platformwill have a suffix of .h62. For the C2800 platform, the suffix will be .h28.For a C64x, C55x, or C28x DSP platform, substitute 64, 55, or 28 foreach occurrence of 54. Also, each reference to Code Composer StudioC5000 can be substituted with Code Composer Studio C6000 dependingon your DSP platform. Information specific to a particular device is designated with one of thefollowing icons:Related Documentation From Texas InstrumentsThe following books describe TMS320 devices and related support tools.
