Targets in the C50 domain. The default-C50 target is the default value. When you click OK, the dialog box appears with the parameters of the target. You can edit these, or accept the defaults. The next time you run the schematic, the selected target will be used.
STRING) Default =rsh commands are used to place files on that computer and to invoke the compiler. You should verify that your .rhosts file is properly configured so that rsh will work.
STRING) Default = $HOME/PTOLEMY_SYSTEMS/C50
This is the directory to which all generated files will be written to.
STRING) Default =INT) Default = YES
If this flag is set to YES, then the generated code will be displayed on the screen.
STRING) Default = 768-1279
Address range for C50 Dual Access RAM blocks. C50 Instructions that operate on data run faster if the data is stored in one of the DARAM blocks. Disjoint segments of memory can be specified by separating the contiguous ranges with spaces, e.g. "768-800 1200-1279."
STRING) Default = 2432-6848
Data address range in the C50 Single Access RAM block. This can also specify a valid address range in external memory.
INT) Default = -1
Setting this parameter to N makes the target attempt to generate a subroutine instead of in-line code for a star if the number of repetitions of that star is greater than N (use N=0 to generate subroutines even for stars with just 1 repetition). Set subroutines? to -1 (or any other negative integer) to disable the feature.
default-C50 target.
asm generated by the other targets, this target will produce a second file (fileDSK.asm) which is the same as the original file but with all lines truncated to 80 characters. This is done because the TI DSK assembler will give false error messages if lines in the input file exceed 80 characters. The options are identical to those of default-C50 target with four exceptions:
asmc50 fileDSK.asm where fileDSK.asm is the name of the file containing the generated code. This should run the DSK assembler and produce a file fileDSK.dsk. Note that asmc50 can be a shell script that invokes the user's DSK assembler. Scripts to use the TI DSK assembler and loader in Linux are presented at the end of this section.
loadc50 fileDSK.dsk which should load fileDSK.dsk to the DSK board. Note that loadc50 can be a shell script that invokes the user's DSK loader.
STRING) Default = 768-1270
Valid addresses on the Dual Access RAM block 1. The last 9 words in this (addresses 1271 - 1279) are reserved by the target to store configuration information for the Analog Interface Chip.
STRING) Default = 2432-6847
Valid addresses on the Single Access RAM memory. Locations 6848 - 11263 are reserved to store the user's program and locations 2048-2431 are reserved by the TI DSK debugger kernel.
dosemu (a DOS emulator). Note that before invoking the assembler and loader Ptolemy executes a cd to the directory target parameter. Since you need to unmount the DOS partition to run dosemu you can not have directory set to the DOS partition. One solution is to set directory to your home directory and set file to include the path to the directory where you want the file written. For example, if your home directory is /ptuser, the dos partition dosemu will use is /dos/c and you want the output files written to /dos/c/dsk/src the you could set directory to /users/ptdesign and file to /dos/c/dsk/filename where filename is the name of the output file. These scripts are also included in $PTOLEMY/src/domains/c50.
