OpenPIC standard or MPIC standard document

Question

Where can I get any document specifying the OpenPIC and MPIC standard ?

Answer 1

There was never any complete documentation for OpenPIC released. The closest thing was documentation for the for the AMD 19725c OpenPIC controller. It used to be located at http://www.amd.com/html/products/pcd/openpic/19725c.pdf, but it seems that the link is broken and searching AMDs site turns up nothing. Your best bet is probably to look at the OpenPIC source code in the Linux kernel.

As for MPIC, you you can look at the documentation for the Intel 80314 I/O Processor.
