[JOS-Kernel] Some Ideas About JJOS

[Hilary Cheng]

Hi,     I got Some ideas About JJOS. It may not be good. : )   1. I have studied JNI before. As a interface between Java and Native Lang.,     They use their own set of primitative type of lang. i.e., they delcare jint instead     of int. jbyte instead of char/byte. It is a good idea for us to design JJOS. Since we     can commuincate Java with Native Lang. using these standard objects.   2. For the Unsigned Operation, It is quite complicated Problem. I suggest a alternative     approach. e.g. As we want to want to add two unsigned byte. we delcare two byte-size     varaible as usual. Use alternate function to performation operation.         byte a = 0xf0, b = 0x02;     byte c = jos.system.unsigned.add(a, b);     int value = jos.system.unsigned.ToInt(c);       We can convert the add or ToInt to a native function during interpertion.     We can using this approach to resolve it.       It may not a good idea. Let's have discussion on it. :)   Regards,   Hilary
