Claim One:
1. An image data compression method for computer processor pipeline trace data, comprising: using a computer, dividing a computer processor pipeline statistic image to be displayed into a plurality of blocks with predetermined block width and block height; creating a block list for indexed blocks containing meaningful pixels in said divided blocks such that indexed blocks associated with each other, wherein said meaningful pixels are pixels corresponding to the computer processor pipeline raw trace data; compressing original pixel information on the meaningful pixels in said indexed blocks and storing it in said block list; reading pipeline trace events one by one from said computer processor pipeline raw trace data; determining pixel position and color of said meaningful pixel corresponding to the pipeline trace event directed to each pipeline trace event read; judging the indexed block to which said meaningful pixel belongs based on the determined pixel position of said meaningful pixel; generating said block list based on red-black tree index information of the judged indexed block; and generating block information on said indexed block based on the pixel position and color of said meaningful pixel determined in said pixel information determining step and a sequence number of said indexed block judged in said indexed block judging step.
