ABSTRACT:
A method for compressing a set of compiled microcode to be utilized within a data processing system is disclosed. In accordance with the method and system of the present invention, all branch instructions within a set of compiled microcode are first identified. Then, the set of compiled microcode is parsed into a number of microcode segments such that each microcode segment begins at an instruction following each identified branch instruction or at a target address of each identified branch instruction. Subsequently, each of these microcode segments is individually translated to its compressed form by utilizing a data-compression routine. Finally, all the compressed microcode segments are concatenated together and linked by inserting branch instructions with modified target address, to yield a set of compressed executable microcode. By doing so, the required memory for storing the compressed executable microcode is reduced.
