Hi ,
    I feel taking a look at SoftWire Dynamic Assembler Project ( ) will give u a better idea of how to
translate the mnemonic sequence into code. The Source code is readable
( as it is written in C++ as opposed to C ). I have used the source
code there to study about instruction encoding for pentium processor.
( And has written a
dynamic compiler for a high level basic like language thanks to that )
