You can change processor type only within the current family. If you have selected IBM PC family, you can not select Zilog 80 family and vice versa.

Processor modules can accept additional options that can be passed on the commandline with the -p switch. Currently only the ARM module supports it. For example, -parm:ARMv7-A will turn on options specific for the ARMv7-A architecture, such as NEON instruction set.

For information about additional processor modules, please visit our web page at https://www.hex-rays.com/products/ida/processors.shtml

Please note that when you change the processor type, IDA may change the target assembler, so check it out.

You may get a message saying that IDA does not know the specified processor if IDA fails to load the corresponding processor module.

        Windows IDA uses .dll file extension
        Linux IDA uses .so file extension
        Mac IDA uses .dylib file extension
NOTE: modules compiled with support for 64-bit address space, will feature a '64' suffix before the extension. E.g., 'pc64.dll'

NOTE: Changing the processor type leads to reanalysis of the whole program. Sometimes this is useful.

NOTE: when you load a new processor module, all analysis options are reset to the values specified in the configuration file.

IDA determines the default processor using the input file extension and the contents of the input file. The table which describes the input file extensions and the corresponding processor types is located in IDA.CFG file and looks like this:

 DEFAULT_PROCESSOR = {
 /* Extension   Processor */
  "com" :       "8086"                  // IDA will try the specified
  "exe" :       "80386r"                // extensions if no extension is
  "dll" :       "80386r"                // given.
  "drv" :       "80386r"
  "o"   :       "68000"
  "prc" :       "68000"                 // PalmPilot programs
  "axf" :       "arm"
  "h68" :       "68000"                 // MC68000 for *.H68 files
  "i51" :       "8051"                  // i8051   for *.I51 files
  "sav" :       "pdp11"                 // PDP-11  for *.SAV files
  "rom" :       "z80"                   // Z80     for *.ROM files
  "cla" :       "java"                  // Java classes
  "class":      "java"                  // Java classes
  "s19":        "6811"
  "*":          "80386p"                // Default processor
}
If you want to change the default processor type, you need to change this table. You may add/delete rows in this table.
