== Cell SPE Task Library ==
quoted intro:<br />
&nbsp;&nbsp;"
''This project contains a thread-safe digital signal processing and computational microtask execution library for the IBM Cell Broadband Engine. It works in Linux and the IBM Cell SDK 2.1 on the Playstation3 and Cell Blade. The project consists not really of a library but of source code and header files that you can include in your Cell program. The license is GNU LGPL.''


''The SPE program is started once on 1..N SPEs, where it will stay running and waiting for tasks that can be sent to it from your PPU program. The running SPE program(s) can be sent different such computing tasks. Tasks can be single or a chained queue of tasks, for example of different types. The SPE program uses faster mailbox communication, and latencies from task start to end on the PPU side are quite low. There is an additional framework for PPU code that makes accessing the computing SPEs and their tasks threadsafe.''

''The set of computational tasks (commands) can be easily extended with your own funcs. The code allows more control over processing, DMAs and buffering than the IBM ALF framework.''
 
''Another point for this project is to collect a bag of computational tricks and fast DSP funcs, in the form of cut&paste source code snippets that you can can copy into your own SPE programs. These code pieces include very fast sine and cosine calculation, complex multiply accumlate, and others.''

'''addendum:''' contact me, adrianc on efnet or adriancps3@gmail.com,
This would work well with IDA Python...
if you wish to donate and help purchase a reference tool for the community.

this has many benefits such as new keys, debugging for all devs, syscon exploits and many more.
 
your support will not be forgotten.
