Using a static analysis (IDA) could give you a good view of what the program does, but sometimes you want to know what a program does in real time and how it reacts to different parameters, this is where anergistics becomes a powerful tool. It simulates the SPU including its communication, and storage.

=== Usage ===
 
anergistic can be launched in two different modes, one that '''only emulates''' (runs) the program through the SPU and the the other that lets you '''debug''' the process through gdb
 
==== only emulate ====
 
{{keyboard|content=<syntaxhighlight lang="bash">./anergistic spu_elf_name.elf</syntaxhighlight>}}
 
this mode runs an elf with all the parameters and actions defined on main.c, channel.c a
 
==== debug ====
 
terminal 1
{{keyboard|content=<syntaxhighlight lang="bash">./anergistic -g1234 spu_elf_name.elf</syntaxhighlight>}}
 
simulate debug server in the local host on port 1234
 
terminal 2
{{keyboard|content=<syntaxhighlight lang="bash">
spu-gdb spu_elf_name.elf
(gdb)target remote :1234
</syntaxhighlight>}}
 
connect to the local host on port 1234
 
(gdb)help will give you information of the command available
 
==== Documentation ====
 
*http://publib.boulder.ibm.com/infocenter/ieduasst/stgv1r0/topic/com.ibm.iea.cbe/cbe/1.0/LinuxOnCell/L2T1H1_31_LinuxonCellToolchainGDB.pdf
*SPU specific commands
**http://sourceware.org/gdb/onlinedocs/gdb/SPU.html
 
this mode performs the same as above but lets you debug the process through gdb
 
=== Customizations ===
 
See example below.
 
'''Running in aim_spu_module anergistic'''
 
=== Problems ===
 
==== Connection problem ====
 
when in debugger mode
<pre>
Waiting for gdb to connect...
Client connected.
recv failed: Success
</pre>
 
==== Solution ====
 
Use spu-gdb.
 
=== Tools ===

Use this to convert IDA disassembly into a format suitable for GNU AS. Literals in IDA are unsigned while AS expects signed literals. Conversion of literals is a work in progress.
 
== Loading Isolated Modules in GameOS ==
 
This code kinda represents how GameOS applications load and execute isolated SPU SELFs. For example: psp emulator.
 
<source lang="C">
  sys_spu_initialize(1,1);
  syscall(230, sys_spu_t *id,img &iso_spuSCEself,void *arg,0,0,0); //sys_isolated_spu_create
  sys_ppu_thread_create(sys_ppu_thread_t *thread_id,void* iso_spu_handler,sys_spu_t *id, 0x64, 0x1000, 2,"iso_spu_handler");
  syscall(233, sys_spu_t *id,2,0,sys_interrupt_tag_t intrtag);  //sys_iso_spu_create_interrupt_tag
  sys_interrupt_thread_establish(sys_interrupt_thread_handle_t *ih,sys_interrupt_tag_t intrtag,sys_ppu_thread_t t_id,
  sys_spu_t id,0);
  syscall(234, sys_spu_t *id,2,7); //sys_iso_spu_set_int_mask
  syscall(232, sys_spu_t *id);    //sys_iso_spu_start
  ...
 
  iso_spu_handler(...) {
  syscall(237, sys_spu_t id,2,void *out1);  // sys_iso_spu_get_int_stat
  syscall(240, void *out2, out1);          // sys_iso_spu_mmio_read / sys_isolated_spu_read_puint_mb ?
  syscall(236, sys_spu_t id,2, out1)        // sys_iso_spu_set_int_stat
  sys_interrupt_thread_eoi()
  }
