A method of executing program instructions may include receiving, in a
processor, an instruction that causes the processor to read data from or
write data to a portion of memory that is shared by one or more
processes, at least one process of which manipulates data in a format
that is different than a format of data in the shared portion of memory.
The method may further include executing alternate instructions in place
of the received instruction. The alternate instructions may effect
transformation of data associated with the shared portion of memory from
a first data format to a second data format.
