Linker Options
This option auto-aligns circular buffers. modulo reverse-carry buffers defined object file input sections relocated independently order optimize placement memory. Code data surrounding buffer packed fill space formerly occupied buffer corresponding alignment gaps. Example: dsplnk myprog.cln This example links file myprog.cln optimally aligns buffers encountered input. -B<objfil> This option specifies that object file created Linker output. <objfil> legal operating system filename, including optional pathname. filename specified, option present, Linker will basename (filename without extension) first filename encountered input file list append .cld basename. option present (see below), explicit filename must given. This because Linker followed default action, possibly could overwrite existing input files. option should specified only once. file named option already exists, will overwritten. Example: dsplnk -Bfilter.cld main.cln fft.cln fio.cln this example, files main.cln, fft.cln, fio.cln linked together produce absolute executable file filter.cld. -EA<errfil> -EW<errfil> These options allow standard error output file reassigned hosts that support error output redirection from command line. <errfil> must present argument, legal operating system filename, including optional pathname. option causes standard error stream written <errfil>; <errfil> exists, output stream appended file. option also writes standard error stream <errfil>; <errfil> exists will overwritten.

Example: dsplnk -Fopts.cmd This example invokes Linker takes command line options input filenames from command file opts.cmd. This option sends source file line number information object file. generated line number information used debuggers provide source-level debugging. Example: dsplnk -Gmyprog.cln This example links file myprog.cln sends source file line number information resulting object file myprog.cld. Linker ordinarily produces absolute executable file output. When option given, Linker combines input files into single relocatable object file suitable reprocessing Linker. absolute addresses assigned errors issued unresolved external references. Note that option must used when performing incremental linking order give explicit name output file. filename were allowed default, could overwrite existing input file. Example: dsplnk -Bfilter.cln main.cln fft.cln fio.cln this example, files main.cln, fft.cln, fio.cln combined produce relocatable object file filter.cln.

-L<library> Linker ordinarily processes list input files, which each contain single relocatable code module. option encountered, Linker treats following argument library file searches file outstanding unresolved references. module found library that resolves outstanding external reference, module read from library included object file output. Linker continues search library until external references resolved more references satisfied within current library. Linker searches library only once, when encountered command line. Therefore, position option command line significant. Example: dsplnk filter main -Lio This example illustrates linking with library. files main.cln fir.cln combined with needed modules library io.lib create file filter.cld. -M<mapfil> This option indicates that file created. <mapfil> legal operating system filename, including optional pathname. filename specified, Linker will basename (filename without extension) first filename encountered input file list append .map basename. option specified, then Linker will generate file. option should specified only once. file named option already exists, will overwritten. Example: dsplnk filter.cln gauss.cln this example, files filter.cln gauss.cln linked together produce file. Because filename given with option, output file will named using basename first input file, this case filter. file will called filter.map. Linker considers case significant symbol names. When option given Linker ignores case symbol names; symbols mapped lower case. Example: dsplnk filter.cln fft.cln fio.cln

this example, files filter.cln, fft.cln, fio.cln linked produce absolute executable file filetr.cld. symbol references mapped lower case. -O<mem>[<ctr>][<map>]:<origin> default, Linker generates instructions data output file beginning absolute location zero memory spaces. This option allows programmer redefine start address memory space associated location counter. <mem> single-character memory space identifiers letter upper lower case. optional <ctr> letter indicating High location counters. counter specified, default counter used. <map> also optional signifies desired physical mapping relocatable code given memory space. Internal memory, External memory, ROM, Port Port <map> supplied, then explicit mapping presumed. <origin> hexadecimal number signifying relocation address given memory space. option specified many times needed command line. This option effect incremental linking being done (see option). Example: dsplnk -Ope:200 myprog -Lmylib This example initializes default memory counter maps program space external memory. -P<pathname> When Linker encounters input files, current directory directory given library specification) first searched file. found option specified, Linker prefixes filename (and optional pathname) file specification with <pathname> searches newly formed directory pathname file.The pathname must legal operating system pathname. option repeated many times desired. Example: dsplnk -P\project\ testprog This example uses pathname conventions, would cause Linker prefix library files found current directory with \project\ pathname. -R<ctlfil> This option indicates that memory control file read determine placement sections memory other Linker control functions. <ctlfil>

INTRODUCTION
phrase "sound field processing" seems embody sense extra space added original sound. With advent practical multichannel sound, processing certain sound fields artificially became attainable edifies listening environment when certain theaters other settings replicated software. order create delay reverberation elements that typify certain acoustical spaces, filtering delay components must instituted. Therefore, DSPs ideally might handle even toughest simulation. soundfield processing example offered here design based around studies performed independently Manfred Schroeder James Moorer1. Each provide important insight into effective algorithms that create artificial reverberation. This appendix will explain specifically reverberation blocks inherent particular example; however, this example provides only many defined Schroeder Moorer. This implementation uses filter coefficients collected Schroeder that imitate Boston Concert Hall. four channel output generated: left front, right front, left rear, right rear; with summed output feeding center channel which also lowpass filtered used subwoofer channel. complete block diagram system shown Figure B-8. software implement this design provided DSP56009 diskette viewing/editing SFPEVM09.ASM downloading onto SFPEVM09.CLD.The SFPEVM09.ASM operated with either DSP56004, DSP56007, DSP56009. basic reverberation elements utilized file, SFPEVM09.ASM, include early reflection filter each four main channels reverberation unit comprised parallel comb filters single all-pass filter. This code written implemented DSP56009EVM.
EARLY REFLECTIONS
Schroeder suggested method simulating early wall reflections room geometry combining direct summation original signal with standard unit reverberator recreate late echos. theory proposes that first gains delays simulate room's geometry patterned after (non-recursive) filter structure; unit reverberator/IIR (recursive) filter imitates decay reverberation once pulses become inseparable.
