Loader for ADSP-2126x/2136x/2137x SHARC Processors The multiprocessor tag, processor ID, and the offset are encapsulated in a multiprocessor header. The multiprocessor header includes three 32-bit words: the multiprocessor tag; the ID (0–7) of the associated processor .dxe file in the lowest byte of a word; and the offset to the next multiprocessor tag. The loader -id#exe=filename switch is used to assign a processor ID number to an executable file. The loader -id#ref=N switch is used to share the same executable file by setting multiple bits in the ID field. Figure 5-4 shows the multiprocessor header structure. 0xB PROCESSOR IDS OFFSET TO NEXT MULITPROCESSOR HEADER Figure 5-4. Multiprocessor Header ADSP-2126x/2136x/2137x Processors Compression Support The loader utility for ADSP-2126x/2136x/2137x processors offers a loader file (boot stream) compression mechanism known as zLib. The zLib compression is supported by a third party dynamic link library, zLib1.dll. Additional information about the library can be obtained from the http://www.zlib.net Web site. The zLib1 dynamic link library is included in VisualDSP++. The library functions perform the boot stream compression and decompression procedures when the appropriate options are selected for the loader utility. The boot kernel with built-in decompression mechanism must perform the decompression on the compressed boot stream in a booting process. The default boot kernel with decompression functions are included in VisualDSP++. VisualDSP++ 4.5 Loader and Utilities Manual 5-35
