Detailed Description
Datatypes supported by MOC.There are the normal datatypes defined by C (char, short, int, ...) and special vector-datatypes used by the Cell Broadband Engine. For more information see "C/C++ Language Extensions for Cell Broadband Engine Architecture - Version 2.5" chapter 1.1.

Typedef Documentation
| typedef uint8_t MOC_Datatype |
Typedef defining MOC_Datatype.
One byte is used to encode the Data-Type. The first four msb hold the size in byte / 2 ( if ((datatype & 0xF0)>>4) == 0 then size = 1 else size = ((datatype & 0xF0)>>4)*2 ) and the four lsb hold an id. The combination of id and size is used to uniquely identify a datatype (or rather a group of datatypes belonging together).
