I'm working with a program at may PC at the Rogaland University Center in 
Stavanger, subbandcoding. The question is: Can the coprosessor work alone, a 
sort of parallell processing, or will the main processor stop and wait until 
the co-processor is finished ? 

I have to know this because I'm going to optimalize the program so it will 
go much faster then the JPEG standard !!!

If i program in assembly direct in the C-program source, will it go much 
faster ? If I program the coprocessor direct (f_xxx ), will that go much 
faster than else ???

Please Answer Me
