Abstract: In a data processing system (10, Figure 1), a set of compiled microcode is parsed 21, into multiple microcode segments, wherein each of these microcode segments is of equal length. Each of the microcode segments is then individually compressed 22 using a data-compression routine. Next, all of these compressed microcode segments are concatenated and linked 23 to yield a set of compressed executable microcode. Finally, the starting address for each of the compressed microcode segments is stored 24 in an indexer. By so doing, the required memory for storing the compressed executable microcode is reduced.
